The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Floating Solar Array Is Designed to Take the Rough Stuff - Rich opportunities for solar co-location with offshore wind. By combining floating solar with offshore wind farms and thereby leveraging the same energy infrastructure and export cables, the resulting energy production capacity per used area could be drastically improved. Prototype has been developed…should be in the water by June 2024.

Lessons In Rewilding the Scottish Highlands – Working with nature…increasing biodiversity…reducing monoculture.

Five Shocking Animal Hybrids That Truly Exist in Nature, From Narlugas to Grolar Bears to Coywolves – I’ve heard about a few of these…the pictures were interesting.

Pregnancy advances your ‘biological’ age — but giving birth turns it back - Brewing a baby leads to changes in the distribution of certain chemical markers on a pregnant person’s DNA — changes similar to those that are a hallmark of getting older. But new research shows that, several months after a person gives birth, the chemical patterns revert to an earlier state.

Did You Know Sandhill Cranes Dye Their Feathers? – The birds rub iron rich mud onto their feathers…staining them. And some trivia about sandhill cranes at the Platte River (Nebraska) in the early spring:

• The birds find a lot of waste corn in farm fields, as well as small invertebrates in marshes near the river. A crane can add 20 percent to its weight during two or three weeks in the area.

• At night, the cranes move to the Platte River for safe roosting in the shallow water.

• Sandhill cranes are the most numerous of the world’s crane species.

• In the Central Flyway, more than 500,000 cranes – more than 80 percent of their population.

The heat index -- how hot it really feels -- is rising faster than temperature - Researchers looked at Texas's summer 2023 heat wave and found that the 3 degree F rise in global temperatures has increased the state's heat index as much as 11 degrees F on the hottest days! Arizona's most populous county, covering most of Phoenix, reported that heat-associated deaths last year were 50% higher than in 2022, rising from 425 in 2022 to 645 in 2023. Two-thirds of Maricopa County's heat-related deaths in 2023 were of people 50 years or older, and 71% occurred on days when the National Weather Service had issued an excessive heat warning. With climate change, the relative humidity remains about constant as the temperature increases, which reduces the effectiveness of sweating to cool the body.

158 Cherry Blossom Trees Will Be Cut Down in D.C. in Effort to Withstand Sea-Level Rise – Part of the project to reconstruct a seawall around the Tidal Basin.

Landscape Architecture Strategies Reduce Impacts of Dangerous Extreme Heat – And these apply to what we do in our yard too!

• Increase tree percentage in parks and green spaces

• Provide shade on sites

• Use plant materials and water instead of hardscape

• Switch to green ground cover, including grasses and shrubs

Plastics Contain Thousands More Chemicals Than Thought, and Most Are Unregulated – Scary! The report also highlights 15 chemical priority groups of concern. These include phthalates, which are used to make plastics more durable and have been found to affect the reproductive systems of animals, as well as per- and polyfluoroalkyl substances (PFAS), which break down very slowly over time and have been linked to health issues including reproductive and developmental problems and increased cancer risk.

Only seven nations meet WHO air pollution standards – The US is not one of the seven: Australia, Estonia, Finland, Grenada, Iceland, Mauritius and New Zealand. Bangladesh, Pakistan, India, Tajikistan and Burkina Faso were the top five most polluted countries in 2023 with PM2.5 levels nine to 15 times higher than the WHO's standard. Columbus, Ohio, was the most polluted major city in the United States, while Las Vegas was the cleanest and Beloit, Wisconsin polluted U.S. city overall.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

As the Mississippi Swerves, Can We Let Nature Regain Control? - After the lower Mississippi began pouring through and enlarging Neptune Pass in 2019, sediment began flowing into a sand-and-silt-starved Delta Bay. Now the Army Corps of Engineers — breaking with tradition — is considering letting at least part of the river have its way…..a change from always ‘filling the breach’ strategy of years past that has had positive economic impacts but caused environmental problems. According to the U.S. Geological Survey, since 1932, more than 2,000 square miles of land in the Mississippi Delta have disappeared under water.

Babcock Ranch: Florida's first hurricane-proof town - When Hurricane Ian made landfall on the southwest Florida coast, it brought 150 mph winds, 17 inches of rain within 24 hours, and storm surges of up to 18 ft. It was the costliest hurricane in Florida's history, causing more than $112 billion  in damage – and at least 150 deaths. Babcock Ranch is an 18,000-acre development that was sitting in the eye of the storm on the southwest of the state just north of Fort Myers. Built to withstand powerful storms, the town came out relatively unscathed. Is this type of development going to be the only kind economically viable for states like Florida in the future?

Year-round school: Difference-maker or waste of time? – No conclusion in this article….evidently there is renewed interest in the idea in the Southeast. But – the concept is not what most people probably assume. The implementation does not involve more days in school for students and often makes childcare more difficult!

What Are Heat Pump Air Conditioners? - Modern heat pumps are superefficient and can deliver heat down to -15 degrees Fahrenheit…but I had to look to find that they can deliver cool air up to 115 degrees which should have been in the article since it was about air conditioning!

Controversial dwarfism drugs spur growth — but do they improve health? – Hard choices.

Microplastics infiltrate all systems of body, cause behavioral changes – Especially in older mice…behaviors akin to dementia in humans. The changes became more profound in older animals. The microplastics in the study were delivered orally via drinking water…and not in high doses.  It’s scary to think about how microplastics might be impacting humans too.

Can California Cropland Be Repurposed for Community Solar? – Evidently the current farming practices are not sustainable, and some farmland needs to be retired. The idea is that the already disturbed land could be repurposed for new community solar projects. I wondered where the food we now are getting from California will be grown in the future…how robust is the US food production system?

TB research shows a good diet can cut infections by nearly 50% - Improved nutrition in family members of patients in India with lung TB reduced all forms of TB by nearly 40%, and infectious TB by nearly 50%. And…for the patients: An early weight gain in the first two months was associated with 60% lower risk of TB mortality. The other benefits were higher treatment success and better weight gain. During the six-month follow-up period, a remarkable treatment success rate of 94% was achieved.

Top 10 Things You Didn’t Know About Wind Power – How many of these 10 did you know already? I knew 4 of the 10…and knew a little about several others. It’s good to see the progress being made. Kudos to Iowa and South Dakota where over 50% of their electricity generation is from wind energy.

Soils forming on the branches of trees are an overlooked forest habitat – This was a study of a tropical forest in Costa Rica, but it reminded me of a tree along a field trip hiking route in Maryland that I always pointed out to students. It was an old maple that had an indention in its trunk that contained soil about 6 feet above the base of the tree. The tree had grown some roots into that soil and there was moss there. Spider webs filled in. Once we found a shed snakeskin hanging from the area!

Two Baby Condors at Pinnacles National Park Are Healthy, ‘Adorable Fluffballs’ – Avian flu killed at least 20 California Condors in Arizona and Utah last spring…so the health of these birds is great news. So far, their lead levels (often a problem if their parents bring them carrion with bullet fragments) are low. They will make their first flights in October or November.

Biden Designates Baaj Nwaavjo I'tah Kukveni - Ancestral Footprints of the Grand Canyon National Monument – Protecting the land around Grand Canyon National Park.

Nearly Two-Thirds of All Species Live in the Ground, Scientists Estimate - Soils are richer in life than coral reefs or rainforest canopies, providing a home to nearly two-thirds of all species. The study is the first to tally the total number of soil dwellers, large and small, finding that more than twice as many species live in the ground as was previously thought: 59 percent of all species depend on soil for their survival, including 90 percent of fungi, 86 percent of plants, and 40 percent of bacteria.

Incredible Winners of Light Microscopy Awards Show Artistry of Scientific Imaging – The beauty of microscopic life….

Research Sheds Light on Steamboat Geyser’s Eruptions, Past and Present – They discovered that the strength of shaking decreased as snow depth increased. The ability of snow to absorb sound makes a difference!

Stunning Fields of Sunflowers Are Blanketing North Dakota – The states farmers grew 625,000 acres of sunflowers this year…and they bloom throughout August. Maybe one year we’ll make the trek to see them; I haven’t been to North Dakota before.

Exceptional Winners of the 2023 Nature inFocus Photography Awards – Beautiful…and educational. My favorite image is the ant with aphids (“A Sappy Alliance”).

What Pots Say—and Don’t Say—About People – “What can such a well-traveled artifact tell us about the people who left it in the ground? Its culture of origin may be less important than how it fit into life where it was found.”

Microplastics found in human heart tissues, both before and after surgical procedures - Everywhere scientists look for microplastics, they've found them -- food, water, air and some parts of the human body….even in the heart. But it still is not known how/if the microplastics impact the cardiovascular system.

Microalgae vs. Mercury - In the search for ways to fight methylmercury in global waterways, scientists at Oak Ridge National Laboratory discovered that some forms of phytoplankton are good at degrading the potent neurotoxin.

Neolithic Necklace from Jordan Reassembled – Jewelry that was beautiful long ago…and still is. Beads of stone and shell primarily.

UNESCO Recommends Adding Venice to List of World Heritage in Danger – UNESCO is indicating that Venice’s proposed solutions are “currently insufficient and not detailed enough and should be subject to further discussions and exchanges.” I’m a little surprised that Venice hasn’t been on the list for years.

'Time-traveling' pathogens in melting permafrost pose likely risk to environment – Quantifying the risks using simulations. The results so far estimate that 1% of the invaders (ancient pathogens) are unpredictable…some could cause 33% of the host species to die out while others could increase diversity by up to 12%. Outbreak events caused by ancient pathogens represent a substantial hazard to human health in the future.

In Peru, discovery of ancient ruins outpaces authorities' ability to care for them – Lima is home to more than 400 known pyramids, temples and burial sites, many of which predate the Incas and are known in Spanish as "huacas"…and archaeologists continue to find/dig new sites! 27 sites are open to visitors…the rest are deteriorating (or actively being destroyed by looters or squatters).

Inflammation discovery could slow aging, prevent age-related diseases – Researchers at the University of Virginia School of Medicine have discovered that improper calcium signaling in the mitochondria of certain immune cells (macrophages) drives harmful inflammation. Creating drugs that increase calcium uptake by mitochondrial macrophages could prevent harmful inflammation and slow age associate neurogenerative diseases.

Piecing Together the Puzzle of Oman’s Ancient Towers – 4,000 years old! And there are over 100 known towers found today in Oman and the United Arab Emirates. The purpose and function of the towers remain largely a mystery although water might be involved. They appear to be built close to places where there is/was access to surface water.

Lake Tahoe’s Clear Water Is Brimming with Tiny Plastics – Its water contains the third-highest amount of microplastics among 38 freshwater reservoirs and lakes around the globe! Lake Tahoe is also full of garbage ranging from sunglasses to car tires; 25,000 pounds of debris was removed from the lake between 2021 and 2022.

Dementia becomes an emergency 1.4 million times a year – And these patients are 2x more likely to be seeking emergency care after an accident or a behavioral/mental health crisis. Once a person with dementia is in the emergency department, it can be a very disorienting experience. "Even routine blood draws from unfamiliar staff can be a very scary experience for a patient with advanced dementia."

Decades of public messages about recycling in the US have crowded out more sustainable ways to manage waste – To often we overlook waste reduction and reuse in favor of recycling.

Steel Industry Pivoting to Electric Furnaces - Iron and steel production accounts for 7% of carbon emissions worldwide – using coal in blast furnaces. But – progress is being made. 43% of planned steelmaking capacity globally will rely on electric-arc furnaces, up from 33% last year! Even so – the rate of transition needs to be increased to stay on track for only 1.5 degrees C warming.

Climate change threatens spring wildflowers by speeding up the time when trees leaf out above them – Evidently the trees and wildflowers in eastern North America are the ones getting the most out of sync.

The mystery of Alice in Wonderland syndrome (AIWS) – AIWS (or Todd’s syndrome) affects the way people perceive the world around them and can distort the way they experience their own bodies and the space it occupies. There are 40 types of visual distortions that characteristic of the syndrome. It was formally described as a distinct syndrome in 1955. Up to 30% of adolescents reported mild or transient experiences. Cough medicines and illicit hallucinogenic substances are also known to trigger it.  Sometimes medical conditions like strokes or brain tumors can cause the syndrome as can infections.

Chinook salmon fishing season canceled off coasts of Oregon, California – Dwindling numbers of Chinook salmon in the states’ largest rivers following years of drought.

In Florida, an invasive snail is helping save an endangered bird – We heard about this during a birding trip to central Florida pre-pandemic. It probably is one of the few examples when an invasive species has produced a positive outcome.

Garbage to Guts: The Slow-Churn of Plastic Waste – Lots of microplastics in the world…and they are in our food chain. Ongoing exposure decreases beneficial gut bacteria and increases pathogenic species. A lot more research needs to be done since, right now, we don’t know very much about impacts of microplastics – not just to the overall environment but to our own bodies.

 With Heat from Heat Pumps, US Energy Requirements Could Plummet By 60% - Thinking about heat….and the ‘rejected energy’ (mostly heat) in our current energy consumption. The idea is to use heat pumps to dramatically reduce ‘rejected energy’ in future energy consumption.

Entire populations of Antarctic seabirds fail to breed due to extreme, climate-change-related snowstorms – Evidently the December 2021 - January 2022 breeding season for south polar skua, Antarctic petrel, and snow petrel was so disrupted that there were almost no young produced.

Why don’t humans have fur – Interesting…but we really don’t know. The genetic research associated with the question could have practical application for people that need to stimulate hair growth (like after chemotherapy or balding).

2021 Was A Very Good Year for Nesting Wading Birds In The Everglades – Hurray! Some good happening in the Everglades. There are so many stories about the impact of invasive species (like Burmese pythons) that this is welcome news.

Meet the sargassum belt, a 5,000-mile-long snake of seaweed circling Florida - In the open sea, sargassum can soak up carbon dioxide and serve as a critical habitat for fish, crabs, shrimp, turtles, and birds…all positive. But when sargassum gets close to shore it can smother coral reefs, alter the water’s pH…and then onshore it begins to rot within 24 hours releasing irritants like hydrogen sulfide which smells like rotten eggs or manure and can cause respiratory problems. And it often contains significant amounts of arsenic so not a great addition to a compost pile. The mass of sargassum has been increasing since 2011 --- probably in response to elevated nutrients (runoff from fertilizer, burning biomass, increasing wastewater from cities, etc.) we have released into the ocean. Sargassum has come ashore in Yucatan and Key West recently.

Macro Photos Highlight the Diverse Beauty of Butterfly Pupae – The pupae are Asian species….so no Monarch chrysalis (which is my favorite).

Good hydration linked to healthy aging – The findings don’t prove a causal effect…but hydration is linked to serum sodium…and chronic high serum sodium (i.e. when a person is dehydrated frequently) increases risk of developing chronic diseases like heart failure, stroke, atrial fibrillation and peripheral artery disease, etc.

The Infrastructure Sector Is Bleeding Workers – The workforce is aging…more are nearing retirement…and younger people are not coming into the jobs fast enough.

This new year – decarbonize your life – The beginning of a series about a family of 4…taking steps to dramatically reduce emissions and sequester carbon.

Gradient Arrangements of Food Highlights Biodiversity Not Often Seen in Supermarkets – Wow – what a range of colors and shapes in common fruits and veggies like: tomatoes, corn, potatoes, pears, peppers, squash, cucumber, kale, and beans.

Heat and cold as health hazards – Controlled experiments on how the body reacts to hot and cold…and the health consequences.

Water Worries: Threatened and Endangered Cultural Sites – Climate change has caused increasing severe rainstorms in the Southwest impacting the adobe walls  in Tumacácori National Historical Park in Arizona and Pecos National Historical Park in New Mexico. Storms, flooding and sea level rise are impacting other parks including Statue of Liberty National Monument, Colonial National Historical Park and the Jamestown Settlement, and Castillo de San Marcos National Monument. The tidal basin in Washington DC is crumbling as flooding increases as the Potomac River rises.

Researchers identify bird species depicted in ancient, finely detailed Egyptian painting – Click on the images to get a larger view of the birds. Key to the second image: a–f rock pigeons (Columba livia); g red-backed shrike (Lanius collurio); h white wagtail (Motacilla alba); i pied kingfisher (Ceryle rudis); j–l unidentified.

How microplastics are infiltrating the food you eat – Right now microplastics are viewed as a contaminant but research is revealing they may have harmful impacts….and should be studied and regulated as a pollutant. Will systems that use sludge as fertilizer need to change dramatically? It appears likely.

2022 Year in Review: Top Stories from Around the National Park System – Flooding at Yellowstone, Mauna Loa eruption, drought at Glen Canyon, maintenance challenges, invasive species …crowds…a lot of big stories.

After a shaky start, airborne wind energy is slowing taking off – Another way electricity might be generated in the future…but still a lot of work to be done.

Crews working to cull 600-900 bison from Yellowstone’s herds – I guess this happens every year at this time…even though in the rationale to cap the Yellowstone herd at 5,000 animals involved the mistaken idea that the bison were spreading brucellosis to cattle herds (research has shown that it is elk that spread the disease).

What damaged that tree? Probably not what you think – I guessed correctly….but only because I had seen something similar on a tree during a naturalist led hike…and they had identified the animal that make the marks!

The mystery of Mexico’s vanishing stream oaks – A great piece of trivia: Mexico has more species of oak tree than any other country! The article is about trying to save one of those species.

Three in four people worldwide support a ban on single-use plastic – Wide support…but no clear path on how we can do it. As a consumer – I try to avoid single use plastics, but some products don’t come in any other kind of packaging!

Seeing ‘green’ can ease confusion, anger in navigating hospitals – It’s not just hospitals that could use more natural views and ‘green.’

Top 25 birds of the week: waterbirds and seabirds – Terns, scoters, herons, gulls, cormorants, ducks, spoonbills, kingfishers, sandpipers, plovers, grebes…enjoy the photographs!

Warming temperatures are turning Antarctica green – Another indicator of how fast the Earth is changing….and that even Antarctica is not immune.

Drought depletes a reservoir in Spain, revealing a ghost village – The dam was installed in 1992 so this is not an old reservoir. The US is having similar drought related problems with Lake Mead behind Hoover Dam installed in 1935.

After 25 years at sea, shipwrecked Lego pieces are still washing ashore on beaches in England – Plastic is very durable…the pictures of the small Lego pieces still look pristine. Some of the pieces sank…some floated…they are all moving around and, very slowly, breaking down either in the ocean or on the beaches of Cornwall.

Photography In the National Parks: My 10 Favorite Shots From 2021 – I only went to one national park in 2021: New River Gorge (in West Virginia). There are so many beautiful National Parks to see…and they’re worth seeing again and again.

Big Gulp: Blue Catfish Eat Wood Duck – We’ve seen fishermen catch blue catfish at the base of Conowingo Dam (we’re there for the bald eagles). They are huge…sorry to learn that they eat ducks.

Top 25 birds of the week: Raptors! – How many of these live in your area of the world?

Air Pollution Makes It Harder for Bees to Sniff Out Flowers – Not just a problem for bees…also moths, hoverflies and butterflies are having a harder time. This results in a 14-31% reduction in pollination among plants exposed to polluted air.

Ocean microplastic pollution may be greater than estimated – Not a good trend…and this form of pollution that is new enough that the full impact is still being discovered.

With Fewer Animals to Move Their Seeds, Plants Are Stuck in Threatened Habitats – Another way the world is becoming less resilient at a time when climate change is pushing all life to use all the resilience available.

Large Permian Basin Methane Leaks Are Causing As Much Climate Pollution as 500,000 Cars – It’s frustrating that the oil industry has not been a better steward of resources they are extracting for energy. The methane leaks are a waste of the effort put into extraction….and bad for the planet too.

Dinosaur food and Hiroshima bomb survivors: maidenhair trees are ‘living fossils’ and your new favorite plant – Learn more about the ginkgo tree! There is one along my walking route in my neighborhood and others I find in local gardens and parks near where I live. They are so different from other trees…worth noticing.

North Sea Fossil Fuel Companies Plan to Invest More in Wind than Oil Drilling – Hurray! Maybe other companies around the world begin to do this too….a strategic move for Shell, Total and BP.

Antimicrobial resistance now a leading cause of death worldwide, study finds – This challenge will increase over time…if we don’t take action to slow the development of resistance and develop new antimicrobial techniques (maybe we need more strategies than simply trying to develop new antibiotics).

The great experiment to put a price on nature – Whether it’s toting up ecosystem services or simply realizing that Mother Earth is our one and only…we should all realize that we need to start taking care of ‘nature’ a lot better than we have in the past.

Microplastics May Be Impacting the Climate, Study Finds – A starting point for combining climate science and microplastic science into a model….still a lot if refinement/additions. We already know that the microplastics in our atmosphere are increasing so whatever impact they have it will likely be increasing during the time the model is being refined.

Ancient Stone Ram Heads Unearthed on Egypt’s ‘Avenue of the Sphinxes’ – New finds…and part of an advertisement for some restored places reopening in early November. Are tourists ready to travel again to places like Egypt?

Spending time in nature promotes early childhood development – A study from metro Vancouver of 27,372 children from birth to age 5… that pushes us to get serious about making sure spaces for children include a lot green space…that includes day care and preschools and K within the age range for this study. And while we are doing that – let’s think about how important green space is to everyone else too.

Meet the muskrat: push-up champion of cattail marshes – This article made me wonder if muskrats eat phragmites – and a plant that is taking over marshes. I found an article that says they do…at least in some situations.

Changing ocean currents are driving extreme winter weather – Looking at the impact of the slowing Atlantic Meridional Overturning Circulation (AMOC) and extreme cold weather (like in Texas last February) using a high-resolution global climate model. They’ve only done the simplest model (turning off the AMOC) so far…but plan to refine it to address the more complex reality.

Finding Fall Colors At Bandelier National Monument – I hope everyone found someplace to enjoy fall colors these past few weeks. My main opportunities were in my own backyard and as I was driving down the highway between Maryland and Texas!

Cheers! Wine’s red grape pulp offers nutritional bounty – Not compost or fodder...getting more than wine from vineyards!

Hit the sleep ‘sweet spot’ to keep brain sharp – Evidently 5.5-7.5 hours of self-reported sleep is about right.

Kilauea Resumes Eruptions At Hawai'i Volcanoes National Park – Exciting times on the big island…

In UK, Interest in EVs Spikes Amid Fuel Shortages – There have been stories about Ford and GM strategy recently too….lots of indicators that many people will be buying EVs sooner rather than later if enough are produced.

NASA lander records the largest ‘Marsquakes’ ever detected – The lander has been on the surface since 2018!

Dental care: The best, worst and unproven tools to care for your teeth – Hmm….I wonder how much this research will change what dentists advise?

Baby Poo Has Ten Times More Microplastics Than Adult Feces – A scary result…and no ideas on how to reduce exposure (and we don’t know exactly what harms it might cause)….just more research needed. Very frustrating.

Coastal Northeastern US is a global warming hotspot; 2 degrees Celsius of summer warming has already occurred – From Maine to Delaware…the area is warming faster because of climate change linked alterations in the ocean and atmospheric conditions of the North Atlantic.

2021 Nature Conservancy Photo Contest Winners Highlight Global Wildlife and Nature – Beautiful…and thought provoking. My favorite was the artsy one at the end…a high key image.

Paradigm shift in treatment of type 2 diabetes to focus on weight loss – There are probably other chronic ‘diseases’ that have become more prevalent over the past few decades that could be improved with weight loss….but it is hard to lose weight…and keep it off. It requires permanent lifestyle changes.

A Leisurely Trip to Kansas – Another post that includes pictures of a rough green snake. I’ve been on the lookout for them since my son-in-law sent a photo he took with his phone!

Top 25 birds of the week: Conservation – This is the second. These posts encourage me to get outdoors in areas near my home to photograph birds!

How giraffes deal with sky-high blood pressure – Multiple differences between giraffes and humans when it comes to blood pressure!

Permafrost Thaw in Siberia Creates a Ticking ‘Methane Bomb’ of Greenhouse Gases – The article is about what happened in summer 2020…made me wonder about what is happening this summer in Siberia. This along with the fires that seem to be worse each season are signs that climate change is happening faster than anticipated…that the models might be optimistic rather than realistic.

Plastic, the Trojan Horse – A study that found plastic accumulation in foods may be underestimated. Not good.

Smoke Across North America – Lots of fires this summer. My husband told me that the local astronomy club has cancelled several nights they’d planned for observing because no stars were visible through the haze here in Maryland.

How the sun affects our skin – An infographic about vitamin D, sunburn and skin cancer.

This catfish doesn’t just move on land, it reffles – Plecos – from the aquarium trade – are now invasive in warmer waters in the US. They do have an interesting way of moving on land (videos of their reffle)…..this means if found/caught they shouldn’t be left on the bank to die (since they will easily move back to the nearest water). The article didn’t say what to do with them (presumable kill them).

Drought, Heat Taking a Toll on National Parks in Southwest – I’ve enjoyed so many of the parks mentioned in this article – Saguaro, Grand Canyon, White Sands, Petrified Forest. It has always been dry there…but now it is getting drier and hotter.

Water treatment: Removing hormones with sunlight -- ScienceDaily – Research to find and remove micropollutants. Micropollutants have become more concerning over the past few years as research has shown the potential for health impacts.

Which processed foods are better than natural? - BBC Future – Processed foods are not all unhealthy. Some are better than fresh (for example, canned tomatoes, pasteurized milk). But watch out for ultra-processed foods – ones derived from foods and additives; they can alter gut bacteria, cause inflammation….and many people have a tendence to overeat ultra-processed food.

Top 25 birds of the week: endemic birds – Birds found only in a small area of the world…and no where else. My favorite is the Bee Hummingbird – smallest hummingbird in the world and only found in the Cuban archipelago.

Dietary cocoa improves health of obese mice; likely has implications for humans -- ScienceDaily – Hmmm…maybe my 2 squares of dark chocolate for 1st breakfast is not a bad thing at all…even though I am not obese.

Chipmunk Quest – We have had chipmunks around our house periodically. They are fun to watch. They seem to taunt our cat through the window!

Why Bald Eagle Populations Soared in the Last Decade | Smart News | Smithsonian Magazine – A good news story of species recovery.

Europe’s Drive to Slash Plastic Waste Moves into High Gear – Hope similar efforts are made in the US. As an individual, it is hard to avoid single-use plastic although I have made an effort to avoid plastic shopping bags and buy products in paper/metal rather than plastic when that is an alternative.

Move Over, Cicadas: 5 Other Great North American Wildlife Hatchings (and Emergences) – The Brood X cicada emergence is beginning to wane in our area….it was interesting to think about other emergence type events. Maybe one of the events mentioned in this article will motivate a road trip in the next year or so.

Tropical species are moving northward in U.S. as winters warm: Insects, reptiles, fish and plants migrating north as winter freezes in South become less frequent -- ScienceDaily – Shifts already observable…others projected.

Discarded Covid-19 Masks and Plastic Gloves Are Killing Wildlife | Smart News | Smithsonian Magazine – Ugh! I’m always upset if I see PPE litter; disposable of them properly so they don’t escape into the environment. I will be following the suggestions of ‘snipping the straps on disposable masks’ before I put mine in the trash. I haven’t been using gloves…just soap/water and hand sanitizer.

A mild way to upcycle plastics used in bottles into fuel and other high-value products -- ScienceDaily and How Paving with Plastic Could Make a Dent in the Global Waste Problem - Yale E360 – Two articles about uses for the plastic waste that is overwhelming the planet right now. There still needs to be significant testing on plastic for paving: will it withstanding heavy traffic…will it shed microplastic particles, etc.

Pompeii's Museum Reopens With Dazzling Display of Archaeological Treasures | Smart News | Smithsonian Magazine – I enjoyed the article…and the website for the new museum.

A large number of gray whales are starving and dying in the eastern North Pacific -- ScienceDaily – Ongoing research but one explanation being explored in a decline in prey (i.e. amphipods) availability in their Arctic feeding grounds – maybe caused by warming there due to climate change.

They have roamed wild in southern Florida for a decade…and now are spotted around the southeastern US. It loves to eat eggs and thus is a threat to native species like quail, turkeys, alligators, and tortoises. The race is on to try to stop the invasion of this reptile.

Hawai’i Island Festival of Birds

Wow – 5 days of the virtual Hawai’i Island Festival of Birds. Like the other virtual festivals we’ve seen….I want to go to the Hawai’i festival some year…the sooner the better! When we travelled to the big island in 2015, it was before we’d been to any birding festivals and I took only a few (poor) pictures of birds.

When we go back – I’ll be more prepared after having the experience of this virtual festival. My cameras (and photographic skills) are better than in 2015 too.

The sessions were pre-recorded and not as lengthy some of the other festivals. This was the only festival where native names and language (Hawaiian) were an integral part of the festival.

I listened to all the sessions…even the ones that were readings of books for children about Hawaiian birds….and I learned something from them all.

Day 1 was the longest because I also watch the two virtual field trip sessions:

• An interview with the authors/photographer for the Field Guide to the Birds of Hawai’i…how it was put together and introducing a topic woven throughout the conference - the extinctions of native birds and actions to help the surviving species

• Natural history and status of Hawaii’s seabirds….the impact of sea level rise on Midway Atoll where 91% of seabirds nest in Hawaii…and translocation projects to higher islands (islands within islands to keep mammalian predators out of nesting areas). Pacific Rim Conservation

•  A Virtual Tour of Hakalau Forest National Wildlife Refuge…only place in Hawaii where native forest birds are stable and increasing…We’d get a guide or go with a tour group from the festival when we go. Birds are hard to see in the forest!

• A Virtual Tour of Kaulana Manu Nature Trail … newly opened…off the saddle road on the big island. There is good signage and it’s something we could do on our own. There was a decontamination station for cleaning boots; there is a fungus that causes Rapid Ohi’a Death…a tree that many native birds depend on.

• The status of eBird, Merlin, and Community Science in Hawaii….I need to remember to load Merlin’s Hawaii pack before we go!

• Choosing the best binocular for You!...some binoculars have a short enough minimum focus distance that they can be used for butterfly watching; I quickly decided that, for me, I’d rather use my camera’s zoom to get close images of butterflies rather than watching them through binoculars. But – I did hear about Insect Shield Scarves…which might be something to have for warm weather birding!

Day 2:

• Marvelous Moli…The albatross…The speaker wrote a book – Holy Moli….If we want to see them on nests we’ll have to go to Kauai. Maybe the festival will have a field trip for that.

• Kolea…Pacific Golden Plover…learned a lot about how tagging has evolved over the years and how sophisticated tagging has shown how long and exact their migration is. The book by the speaker found here.

• Hula and storytelling….listening and watching…like a meditation

• Albatross of Kauai, the story of Kaloakulua…a particular Laysan Albratross from 2013/2014 season

Day 3:

• Papahanaumokuakea Marine National Monument…a big place…not sure how we would ever be able to visit

• Garbage guts…a children’s book about plastic garbage in the sea and a Laysan albatross

• Tracking the endangered ‘Akiapola’au…with transmitters and receivers in the Pu’u maka’ala Natural Area Reserve. I remembered that my daughter and I walked around part of that reserve in 2015. I didn’t photograph any birds, but I did take one of my favorite pictures of the whole trip just as we left the fenced area heading back to the car – a camellia among tree fern fronds

Day 4:

• Albatross…doing nest counts….they live very long lives (there is a female that was tagged in 1956 on Midway Atoll that is still producing healthy chicks there!)…World Albatross Day was June 19, 2020

• A Perfect Day for an Albatross (book)… the author talked about producing the book and demonstrated her block print technique before the book was read by 2 educators at Kauai

• Manu, the Boy who Loved Birds (book)…author talking with the publisher and the expert that helped with the book…and then a reading of the book…thinking about recent extinctions and what we can do to help surviving species in Hawaii

Day 5

• Hawaii Wildlife Center…bird assistance/hospital and conservation programs…I learned that warm water is required if birds need to be washed because their normal temperature is higher than ours and if they are injured/oily/emaciated, they will go into shock if washed with room temperature water!

• Manu-o-Ku (white tern) nesting in Honolulu…what happens when the chick falls out of the nest? Most of the time, volunteers are called and it’s put back in the nest or in the tree close to the nest…and the parents welcome it back!

• No Ka Manu Hea Keia Nuku? (To which bird does this beak belong) (book) – In Hawaiian and about Hawaiian birds! It was a great finale to the Festival.

And after all the joy of the videos, I won a drawing for a festival swag pack that will be coming in the mail! The virtual festival was a great addition to our mid-October during this pandemic year!

How cutting your food waste can help the climate - BBC Future – Over the past few years, I have started composting and reduced my food waste by eating food – never forgetting what I have in the refrigerator. Keeping a mental inventory of fresh fruits and veggies…freezing anything that I might not use before it goes bad….has been key. I enjoy frozen bananas in smoothies more than the unfrozen! This time at home (social distancing) gives me an opportunity for another round of reducing food waste….although it’s harder now since I’ve done all the easy actions.

Reducing Single Use Plastic

As we near the end of 2019, I am taking stock of the changes I made over the past year to reduce my household consumption of single use plastic.

We’ve done the easy things at this point:

Switching to reusable shopping, grocery, and produce bags

Choosing products in paper/cardboard, glass, or metal containers rather than plastic containers

Turning some single use plastics into multiple use plastic

Carrying a spork to avoid plastic eating utensils

Bringing our own reusable water bottle and/or travel mug

Replacing broken plastic containers with glass or metal ones (an example happened recently – I bought some glass left-over containers with silicone covers that can be used in the microwave, oven, refrigerator and freezer…and go in the dishwasher for cleaning….some older plastic containers had cracked…so it was an opportunity to change)

When I look at our trash and recycle there are still some opportunities:

• We could stop drinking soft drinks (a health choice for ourselves and the planet).

• We could eat fewer foods packaged in plastic (bunched greens rather than ones in bins or bags, loose apples and potatoes rather than in a plastic bag, unpackaged fresh foods rather than frozen foods, etc.). Sometimes those are a healthier choice as well.

• We could use fewer kinds of toiletries and shift to larger containers (maybe refilling small ones if needed for travel)

But some things are very hard without companies making packaging changes:

• Liquid laundry and dishwasher detergent

• Cleaning fluids like large jugs of white vinegar, surface cleaners, toilet bowl cleaners

• Meat packaging

• Plastic envelopes

• Plastic bubble or balloon wrap

• The list goes on and on

Reducing single use plastic around our house is an continuing goal…and it’s not an easy one.
