Josey Ranch – September 2023

My visit to Josey Ranch (Carrollton TX) was shortly after sunrise. The two resident swans were still asleep on the larger pond….but there was a reflection of morning light on the water…which made the photograph worth it.

My visit to Josey Ranch (Carrollton TX) was shortly after sunrise. The two resident swans were still asleep on the larger pond….but there was a reflection of morning light on the water…which made the photograph worth it.

A Great Egret was fishing in the shallows. The water is low…so the shallows are a larger area of the pond now.

The surprise of the morning was 2 juvenile Little Blue Herons. I had seen one at Josey Ranch in August but seeing 2 caused me to wonder if they had hatched nearby. They both were looking for breakfast in the shallows. These birds will probably be migrating to south Texas (or further south) soon. Or maybe these birds were only at Josey Ranch as a rest stop during their migration.

Both the Great Egret and one of the Little Blue Herons were hunting next to each other at one point! The image shows the relative size of the two birds.

Hagerman National Wildlife Refuge – September 2023 (2)

I saw more than birds at Hagerman in September. There were large numbers of dragonflies in the air. I managed to see one sitting on a bit of dried grass near the road; photographed it through my open car window (like I do almost everything along the road through the refuge). There seemed to be so many dragonflies; it’s a good sign that there is a healthy population at Hagerman; they’ll lay eggs in the ponds where the larvae will overwinter – food for fish.

I did get out to photograph a large piece of driftwood that was on an island in the deepest pond. I liked the curves and the mystery of how it ended up positioned the way it was. Were their branches buried in the silt that kept it from falling over?

Back at the butterfly garden, I photographed three types of butterflies. I had seen all of them on previous visits.

The Monarchs were more numerous this time and I realized that they were probably migrating south to Mexico for the winter.  Supposedly the ones that make the long journey are larger than the ones that live their whole life during the summer months – never making a migration. Will there still be Monarch’s coming through when I return at the end of October? Maybe. The first frost in the Hagerman area is usually not before mid-November.

There was a bumblebee enjoying the flowers. I tried to photograph it from different angles.

Hagerman National Wildlife Refuge – September 2023 (1)

It was a very hot day when I made the road trip from Missouri to Texas in September. It was over 90 degrees when I made the exit to go to Hagerman – thinking that maybe the government would shut down before I headed home, and I wasn’t sure if the refuge would be accessible then.

There were a few migrants at the refuge that I hadn’t seen since last spring: White-faced Ibis,

Neotropic Cormorants (evidently this bird is expanding its range), and

I didn’t see any of the migratory ducks…maybe they will be there next month,

There were the usual egrets and herons. A snowy egret strutted in the shallows.

Several of the great blue herons looked like juveniles.

Some of the egrets (great and snowy) and a great blue heron were enjoying feeding in grassy areas that had been flooded.

I saw a snag with at least 8 white birds in it.

I zoomed in to take as many pictures as I could of individual birds. There were snowy egrets,

Cattle egrets, and

A juvenile little blue heron!

A great blue heron and great egret were on a snag in the water – the heron had just gotten a fish….the egret looks on.

Hagerman was ready for more birds that were probably coming soon in increasing numbers…and some will stay for the winter. Hopefully I will see more of them when I go in October.

Tomorrow’s post will focus on the non-bird sightings at Hagerman in September.

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.

Cyprus’s copper deposits created one of the most important trade hubs in the Bronze Age – Cyprus was part of the first period of international trade in the Mediterranean. It was the largest copper producer around the area. Imports found via excavation included item from close countries like Greece and Egypt; items from distant places like Sardinia, the Baltic Sea region, Afghanistan, and India have also been found. Aside from copper, pottery produced in Cyprus at that time was exported and had been found in excavations around the Mediterranean and beyond.

Green Winter: Europe Learns to Live Without Russian Energy – “In a year when planetary emissions edged upward, Europe is now on track to comfortably outpace its pledge to generate 40 percent of its total energy from renewable sources by 2030.” Impressive.

Australia’s extinct giant eagle was big enough to snack koalas from trees – Likely one of Australia’s top predators during the Pleistocene.

Why East Antarctica is a 'sleeping giant' of sea level rise – The eastern part of Antarctica was thought to be resistant to global warming. In 2012, the East Antarctic ice sheet gained mass overall. But recently, it appears that some ice shelves are melting and might be at risk to collapse. The ice shelves in front of glaciers act as a safety band that keep the glaciers for speeding up and reaching the ocean. Scary comment from the article – “Most of the uncertainty about how much and how fast future sea levels will rise comes from how the East Antarctic Ice Sheet is going to behave.”

Arctic climate modelling too conservative – And about the other pole…researchers at the University of Gothenburg argue that the rate of warming will be faster than projected….and climate models need to reflect the processes occurring there.

In Eastern U.S., Climate Change Has Extended Forest Growing Season by a Month - Scientists tracked American elm, black walnut, white oak, and four other species in northwest Ohio, comparing their data to records collected by an Ohio farmer (Thomas Mikesell) from 1883-1912.

Can clothes ever be fully recycled? – Evidently a lot of progress has been made in the past few years – translating processes from small to large scale production. But recycling is not the only thing that needs to change about the fashion industry. ‘Fast fashion’ is cannot the future!

A simple thing you can do to benefit backyard birds and bees – Wait until it is 50 degrees to do spring cleaning around your yard. Those leaves and dead stalks harbor insects….and birds need insects, particularly when they are raising their young! I have a big tuft of ornamental grass which I am waiting to cut. Last summer it was full of insects and I except some eggs/larvae are there now.

See Thousands of Sandhill Cranes Gather in Nebraska – Maybe next year we’ll plan to go to Nebraska to see the crane migration!

The beautiful flowers that bees can’t use – Nectar deficient hybrids (like double petal petunias) or non-native plants often don’t provide food for pollinators…even though people find bigger, brighter flowers appealing. The article also provides a link to a free book: Pollinator-Friendly Parks which might be useful for homeowners who want to support pollinators.

Anti-dust tech paves way for self-cleaning surfaces – Wouldn’t this be nice…my computer screens seem to attract dust!

'The Great Displacement' looks at communities forever altered by climate change – A book review that documents people surviving a hurricane in the Florida Keys or a big fire in California (and other climate change related disasters) and making decisions in the aftermath. A quote from the author, Jack Bittle: "In the United States alone, at least twenty million people may move as a result of climate change, more than twice as many as moved during the entire span of the Great Migration."

No breathing easy for city dwellers: particulates – Southeast Asia has seen the largest annual average increases in concentration and mortality rates between 2000 and 2019 from this type of air pollution.

How climate change is leading to bigger hailstones – The records for the largest hailstones have been broken in the last 3 years in Texas, Colorado and Alabama….reaching sizes of up to 6.2 inches in diameter. Large hail causes a lot of damage…if the incidence of large hail increases the damage/costs will trend higher too; the post includes a picture of a car damaged by large hail…daunting to anyone that doesn’t have their car parked in a garage.

Missouri Man Indicted For Fire That Destroyed Ozark National Scenic Riverways Visitor Station – I am paying more attention to news about natural areas in Missouri…now that I am preparing to move to the state.

How to fight microplastic pollution with magnets – Many people filter their drinking water…but the conversation about filtering microplastics is newer. Hopefully filters that are effective and affordable will become the norm. It will take a long time to reduce the microplastic load already in the Earth’s water. We are just not recognizing the damage they are causing.

Americans Moving to Disaster-Prone Areas, Despite Climate Change – I’ve started to think about this more recently so appreciated seeing this post. Taking climate change into account – why would anyone buy property in areas that will be increasingly flood prone or incredibly hot/dry? A house nestled in a forest may look appealing but there are an increasing number of people that have already experienced the hazards of that beauty.

1,800-Year-Old Flower Bouquets Found in Tunnel Beneath Teotihuacán Pyramid – I visited Teotihuacan in the spring of 1966 when my parents took me to Mexico City. It was one of the highlights of the trip. The new discoveries are interesting….and I am thinking about whether I would like to see it again. Maybe in spring of 2026? The article references a site with some great pictures of Teotihuacan – worth a look.

Top Solar States Per Capita 2012 vs. 2020 — CleanTechnica Report and US Energy Dept. Aims For Affordable Solar Power – Two posts about solar power. The first article shows the growth since 2012. In states where there wasn’t much growth, I wondered if the utilities in the state or the state government posed barriers to solar power. It seems like the whole country  should be in the mode of getting out of the way or encouraging renewal energy. The second article was about community solar programs from DOE with a mission to ‘bring affordable solar power to every household in the US by 2025’ – a worthy goal but is there enough money in the pipe to do it? This is not a technical problem as much as ‘are we ready to just do it.’

Lullabies in any language relax babies -- ScienceDaily and Baby Bottles Can Shed Millions of Microplastic Particles: Study | The Scientist Magazine® - I’ve been thinking recently about how much things have changed since my daughter was a baby over 30 years ago. I had a lullaby tape (in English) that I played for her in the evenings (although when she got old enough to choose – she wanted soundtracks from Disney movies as often as the lullabies). Now – we’d have digital music playing (rathe than cassette tapes) and maybe there would be lullabies in different languages too. The second article is about some worrisome research and I hope that pediatricians are keeping up and advising parents on best approaches.

Cape May Fall Festival

Friday through Sunday were three intense days of webinars from New Jersey Audubon’s Cape May Bird Observatory (CMBO): the virtual Cape May Fall Festival We enjoyed their virtual festival last spring as well (posts for day 1, day 2); the organization tweaked a few things for this fall one that made it even better; I noticed the roving reporters out in the field and a little bit longer breaks. The days still started at 7 or 8 AM and ended at 5 or 6 (with one evening session after a 2-hour break). I learned to use the breaks to get up and move!

There is a lot of bird monitoring activity (Avalon Seawatch, Cape May Hawkwatch, and Morning Flight Songbirds) in the fall and the CMBO makes it easy to see the results with the buttons for Real-time Counts via Trektellen on their website(near the bottom of the page).

The weather was perfect for a big morning flight of songbirds on Saturday – 27,000 birds in 6 hours! See the Saturday results here – and check out other days going forward. There were huge numbers of warblers. The little bit larger songbirds that we saw (through the great work of the person filming the roving reporters) were Northern Flickers and Blue Jays (3,538 and 1,496 were counted for the morning). The songbirds migrate at night and are funneled down from points north to the Cape May Peninsula where most of them drop down for food and rest before continuing on – most of them working their way back to the north and west around Delaware Bay to then continue their southward migration.

The Hawkwatch also saw a lot of birds on Saturday (results here). These birds migrate during the day. There were 194 Cooper’s Hawks that came through.

The Avalon Seawatch had a bigger day on Sunday with over 1,000 (each) black scoters and double crested cormorants.

There were places featured in the talks and roving reports that we had seen in Spring 2019 (like South Cape May Meadows, Cape May Bird Observation Deck, Higbee Beach Wildlife Management Area, CMBO’s Northwood Center) and then the Edwin B. Forsythe National Wildlife Refuge which was new to us. So many places we would like to be!

There is a also a CMBO Monarch Monitoring Project that tags butterflies! Even though the large winter numbers of Monarchs in Mexico were found in 1975, it was not until 1998 when 7 of Cape May tagged butterflies were found there that the debate of where the east coast Monarchs migrated was finally settled. The results of the monitoring at Cape May are reported in a table on the website.

Virtual sessions are great for classroom type presentations too. At birding festivals, I tend to always opt for the field sessions, so this year of virtual festivals has been great for the classroom-based skill building. I particularly enjoyed learning more about raptor id (in flight), winter seabirds of New Jersey, ravens, other bird observatories (international), international birding tours, and the bird id game done by 3 NJ Audubon’s Young Birder Club members (wow….they have impressive id skills and are good at sharing their knowledge). The Cornell Lab of Ornithology provided the one evening session; I learned about Birds of the World (a new subscription based resource) and more about resources I already know about/use:

One of the sessions brought up the topic of some birds eating Monarch butterflies and seemingly not suffering any effects. My husband and I remembered that we saw that on at a previous birding festival…and I looked back through my blog posts to find out where and when and what kind of bird. It was Couch’s Kingbird on Nov. 11, 2017 and I posted about it on Nov. 27th. It was at a woodlot on South Padre Island, Texas during the Rio Grande Valley Birding Festival. I have two of my pictures from that event below. It’s always great to savor the memories of previous sessions an realize how much we seen/learned over the past few years of birding festivals.

Another prompt to think about personal history that was brought up in one of the sessions: What was your ‘spark’ bird (i.e. the one that got you interested in birds)? I tried to think back to birds that I remember from early in my life. Northern Cardinal is one – definitely. They were around in Wichita Falls, Texas….and stand out in any landscape because of their color. I remember some coloring pages from 1st or 2nd grade of various bird species and learning about Baltimore Orioles…but not seeing one until I was over 60 years old! Why didn’t the curriculum feature birds that we were more likely to see where we lived? I also remember being thrilled to see a Roseate Spoonbill the first time I went to Florida for a space shuttle launch in the 1980s; I’m not sure when I first learned about the bird but it was one that I knew when I first saw it in the field.

Overall – the Cape May Fall Festival was 3 days well spent. My husband also ordered the t-shirt for me since it is red ---- a good color for me. We ware looking forward to future festivals that we can enjoy in the field…but learned a lot and enjoyed this one. Kudos to the CMBO for doing this!

Circular voids. I am starting a series of Zentangle tiles that have circular voids in otherwise dense tangles. I got the idea from some Mordecai Ardon paintings (slideshow on Internet Archive here) like Fatal Eclipse shown at the right. My first two tiles are below.

Compost bin. Between rain showers – I put on the boots I have for river field trips and got all my containers of kitchen scraps and spent flower stalks (mostly day lilies) out to the compost bin. It took 4 trips! There have been more things recently that produced more kitchen scraps than usual: fresh corn on the cob, cantaloupe, cabbage cores, and tough onion/leek tops. I’ve learned to save cucumber skins for use in smoothies so those get eaten these days and veggies like beets and carrots just get a thorough scrubbing rather than being peeled. I put all the new scraps on one side of the bin and then turned the other side over on top of it. I should deteriorate very rapidly.

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.

Listening to Silence: Why We Must Protect the World’s Quiet Places - Yale E360 – I realized after 9/11 that most of the modern world sounds at my house are from transportation: planes/helicopters and cars/trucks with occasional yard equipment. While we had a stay-at-home order with this pandemic, it became noticeable as well. There are still times when those noises are subdued or gone. I notice the bird songs in the early morning…when the other sounds don’t intrude. As we skew more toward electric ground transportation….the noise level will notch downward. I enjoy the natural sounds a lot more than our man-made ones.

Declining eyesight improved by looking at deep red light -- ScienceDaily – I wonder if this is something doctors will start prescribing!

Why your organs might reach 100 even if you don't - BBC Future – A summary of some current research areas re aging. There are a lot of different approaches with the primary goal of most being to extend healthy lifespan.  Even if different organs age at different rates…they are interrelated to the body they comprise.

Maryland offshore wind farm could become stop-over for migrating sturgeon, striped bass -- ScienceDaily – I live in Maryland….so this story grabbed my attention. Will the offshore windfarm become a rest stop for fish? And they will offer a convenient infrastructure for researchers to collect data.

Where Will Climate Migrants Go? – THE DIRT – It’s something to think about now. Some coastal cities are already experiencing more flooding even without unusual storm events…and people that can move will probably do so. Will climate trends weigh in decisions about where they move? The article talks about cities and towns in the Midwest that have experienced declining population becoming ‘receiver’ locations. I wondered if people that have discovered that they can work from home during the pandemic – and can continue to do so – will be freer to move to these new locations and still have the same employer! Otherwise there is the challenge of how to sync moving to a new place with a new job.

The chemistry of cats: Allergies, catnip and urine – Compound Interest – Evidently male cats produce higher levels of allergen and have smellier urine…unless they have been neutered.

Ways to keep buildings cool with improved super white paints -- ScienceDaily – White roofs should probably become the norm….it will be hot enough without the added heat island effect caused by a lot of man-made structures with dark roofs.

How humans are altering the tides of the oceans - BBC Future – It’s happening around the world. Dredging river channels and filling in coastal wetlands cause shifts in how tides interact with the land. And then there is sea level rise too. Some places cited in the article that have experienced dramatic change: Cape Fear River in North Carolina (tidal range at Wilmington has doubled since 1880) and the same is true for St. Johns River/Jacksonville Florida. Sacramento’s tides disappeared in the late 1800s because of silt but dredging brought them back and the Thames tidal range was 2 meters during Roman times and 8 meters by the Victorian age.

Meet the Mountain Chickadee – We have mostly Carolina Chickadees where I live in Maryland…this is their relative in the western US (mountains).

Ancient Maya reservoirs contained toxic pollution: Mercury, algae made water undrinkable in heart of city -- ScienceDaily – Mercury from pigments used on Mayan building. Cyanobacteria blooms that made the water smelly and toxic. Not pleasant for a city center!

Unique Activities for Yesterday:

Regenerative Landscaping lecture (via zoom). The lecture was about an hour and my big take away was about the huge environment cost of lawns…and the many dimensions of that cost. The one I hadn’t thought much about before was from the California Air Resources Board fact sheet on Small engines in California (small engines being spark-ignition engines in things like lawn mowers). Their fact sheet says: “In the early 2020s, however, total smog-forming emissions from small engines are projected to exceed those from passenger cars in the South Coast Air Basin because passenger car emissions will continue to decrease. By 2031, small engine emissions will be more than twice those from passenger cars.” For comparison – they show 1 hour of lawn mowing emits as much smog-forming pollution as driving a Toyota Camry 300 miles! This must be an issue in all areas where there is a lot of mowed turf grass – kike most suburbs. There are multiple ways to address the problem and the one discussed in the meeting was transitioning to less lawn or lawn that does not need to be mowed as frequently (or at all). Another way would be to transition to electric mowers and other yard equipment. Right now – the only gasoline powered equipment I have is the mower. I’d been thinking about an electric mower because I don’t like the noise and smell of our current machine. So - this overall air quality issue is just one more reason to do it.

Enjoyed a slideshow of Armand Guillaumin (1841 – 1927) paintings available on Internet Archive here. He was a French impressionist painter and lithographer.

Hummingbirds' rainbow colors come from pancake-shaped structures in their feathers -- ScienceDaily – Hopefully they’ll produce some illustrations for these findings; this article and the materials it came from are just text.

New Discoveries in Human Anatomy | The Scientist Magazine® - It’s surprising the things we are just now discovering about our anatomy. Back in the 1970s when I was getting an undergraduate degree in biology, I remember being disappointed that there was so much obviously missing….and then realizing there were also unknown unknowns (thing we didn’t even know we didn’t know)! In the intervening years more has been researched, but we still have lots to explore.

Processed foods highly correlated with obesity epidemic in the US -- ScienceDaily  - I have kept a food log for the past few years and now am paying more attention to reducing the processed and ultra-processed foods that I buy and eat. Most of us probably intuitively know that the store-bought cookies, chips, snacks, etc. are not what we should be eating. And they aren’t even more convenient than foods like carrots or apple or grapes. I’m skewing my purchases at the grocery store to the produce aisle!

Top 25 Wild Bird Photographs of the Week: Doves and Pigeons - Wild Bird Revolution and Nectarivorous Birds - Wild Bird Revolution – Two groups of bird photos this week…catching up on the backlog.

Image of the Day: Flock in the Night | The Scientist Magazine® - A huge flock of birds picked up by radar going from Cuba…over the Florida straits…on to mainland Florida.

The chemistry of snow and ice – We haven’t seen much snow and ice in Maryland this winter...but it’s a good time to bring up this topic.

Children to bear the burden of negative health effects from climate change -- ScienceDaily – We need to use these types of articles to motivate us to action rather than indifference/depression.

FS1205: Tree-Dwelling Lichens (Rutgers NJAES) – A short description of lichen. Did you know there are at least 13,000 species of lichen?

The 2020 Community Power Scorecard | CleanTechnica – A map of the US and the scorecard with some details – state by state. There is progress being made in the transition to renewable energy!

New, more appealing varieties of kale in the works - UPI.com – I like kale. I buy it in a bunch to avoid plastic bags or containers…use it in smoothies or stir fries or soups (the whole leaf and stem) and as chips. I rarely use it in salads (particularly during the winter when I tend to want something hot rather cold for meals). Chopping it up in the food processor (like in smoothies or before adding it to soups) makes the toughness of the stem and leaves a non-issue. Still – I would try the new varieties. I wonder how long it will be before some of them show up in my CSA share.

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.

BBC - Future - Is city life really bad for you? – Some additional reasons we need to make changes to cities --- if that is where the bulk of humans will live in the future.

A Field Guide to Commonly Misidentified Mammals – Cool Green Science – How many of these animals can you correctly identify?

Blood vessels turning into bone-like particles -- ScienceDaily – The headline caught my interest…bone-like particles in the blood. Then I noticed that the researcher was from the school where I did my undergraduate work back in the 1970s!

Top 25 Wild Bird Photographs of the Week: Raptors and Migration – Catching up on these weekly posts from National Geographic. I always enjoy them.

BBC - Future - Can you cool a house without air conditioning? – We’ve probably had our last 90 degree plus day for the season at this point….but over the long term, I expect broadening the technologies we use to cool our homes and buildings is going to be important.

Turquoise-Tinted Tarantula Discovered in Sri Lanka | Smart News | Smithsonian – Iridescent color that must startle the spider’s prey (or a predator) --- and a discussion of collecting by scientists.

See a different endangered animal in every U.S. state – The map is easy to explore. The Puritan Tiger Beetle was the one listed for Maryland….not something I had heard of before.

Infographic: How Muscles Age | The Scientist Magazine® - A little muscle anatomy lesson – for young and old.

The Earth's Vegetation Stopped Expanding 20 Years Ago - News | Planetizen – Another indication that climate change is already having a worldwide impact?

Forest-killing bark beetles also might help ecosystem, experts say - UPI.com – It’s distressing to see a forest of dead trees…but maybe it’s an indicator that monoculture forests and fire suppression are not healthy. And then there is climate change in the mix as well. The beetles now survive the winter temperatures in much of their range.

Summer Camp Volunteering- Week 4

The theme for last week’s Howard Count Conservancy’s summer camps was ‘Friends in Flight – Bees, Birds, Bats.’ For the activity at Mt Pleasant – I added ‘Butterflies’ to the Friends in Flight list – playing a Monarch Migration game (instructions here) with each of the three groups. The numbered and laminated cards were taped to colorful cones and mug box dice were used for the cards that needed them. The route of cones was set up on the bricked path in the Honors Garden because the grass was so wet everywhere.

All the campers discovered that there are a lot of hazards along with way during migration….and most played the game about 3 times. We tallied the successful and unsuccessful migrations…with the unsuccessful being slightly ahead!

At Belmont, I started the Zentangle® session with a discussion of blue jays and their feathers using some pictures.

Then the two groups of campers made mono-tangles with a feather-like pattern. For the first group (skewed toward the older in the 5-12 years old range), I used 3” square coasters and a finer point pen than they had used before. The younger group used Apprentice tiles and the Sharpie ultra-fine pens. Some, but not all, of the campers had been in the previous Zentangle sessions. Overall – it was an impressive week!

It was the last week of summer camp. I’ll take a little break – but am already looking forward to the fall field trips ramping up soon.

Neandertal slaughters · john hawks weblog – Analysis of 5 sites indicates that Neandertals were excellent tacticians, casual executioners, and discerning diners.

Rare Gemstone Hidden in Ancient Teeth Reveals a Surprising Truth About Medieval Women – Lapis Lazuli found in the remains of a middle aged woman’s teeth and jaw. She was buried in an all-female monastery in Germany sometime around 1000-1200 CE. The researchers concluded that she most likely was painting with the pigment (licking the end of the brush while painting) creating manuscripts.

More solutions needed for campus hunger – A new report states that 9-50% of America’s college students face food insecurity…and that does not include graduate students. There are some programs that could help but often the students are not aware of them…and there may be enough stigma attached to them that students shy away. These are young adults that need adequate nutrition to continue their schooling and growth into adulthood.

Image of the Day: What We've Dumped | The Scientist Magazine® - Yuck! Stuff that washed up on 12 shoreline sites on barrier island along the US Gulf Coast…and it’s all stuff that people put in the water.

Two billion birds migrate over Gulf Coast -- ScienceDaily – Combining eBird observational data helps translate radar data into estimates of bird numbers. The peak time was April 18-May 7. The highest activity is over the west Texas Gulf Coast (Corpus Christi to Brownsville).

US Cancer Death Rate Dropped for 25 Years Starting in 1991 | The Scientist Magazine® - Down 25% over 27 years…a positive trend.  But there are still issues of race and socioeconomic inequality when it comes to prevention and treatment. The trend is not good for obesity related cancers; they are on the rise.

Top 25 Wild Bird Photographs of the Week: December – National Geographic Society Newsroom – I always like bird pictures.

Natural Disasters Caused $160 Billion in Damage in 2018 - Yale E360 – It did seem like there were a lot of disasters last year: fires in California, Hurricanes Michael and Florence…and that’s just the ones in the US.

Medical marketing has skyrocketed in the past two decades, while oversight remains limited -- ScienceDaily – I have been suspicious of medical marketing (particularly ads on television) for some time. The study seems to show that state and federal regulators are overwhelmed.

Image of the Day: Geckos on the Run | The Scientist Magazine® - It must take a lot of energy for the gecko…but it can indeed run across the surface of the water.

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.

How Do We Carry Our Shopping Home Now? | CleanTechnica – I’ve been using my collection of reusable bags for years. Some of them are over 10 years old and still in great shape. Occasionally, I still get a Lightweight Plastic Bag (or a newspaper in plastic, or other plastic bag packaging) which I take back to the bag recycling bin at my grocery store. I’m always sad when I set a grocery cart full of stuff in the plastic bags…hope none of them escape into the environment.

A Harlequin Duck’s Long Cross-Country Migration – Cool Green Science – A bird banded in Glacier National Park migrated to Long Island! Zoom lenses on cameras and binoculars make it possible to record banding info from a distance.

BBC - Future - The small Scottish isle leading the world in electricity – Eigg has an off-grid electric system powered by wind, water, and solar…they average 90-95% renewable energy. The time of year they tend to need back up generators is in the spring.

Implications of access to high-quality fruits and vegetables: Quality has potential to impact consumer selection and consumption in rural areas -- ScienceDaily – There has been a lot of discussion about food deserts in big cities – places that lack affordable, high-quality food. It appears that food deserts occur in rural areas as well.

Top 25 Endemic Wild Birds – National Geographic – The weekly bird photography fix! The chickadee we see frequently in our areas of the Mid-Atlantic of the US is endemic to our part of the world (and is one of the 25 pictured).

New Beginnings: Cherry Blossoms and Helen Taft's Landscape Diplomacy – Some years we manage to see the peak of the cherry blossoms around the tidal basin in Washington DC….but every year we enjoy the cherry tree in our front year. It is always at least a week later than the ones in DC.

US electricity use drops, renewables push fossil fuels out of the mix | Ars Technica – Total electrical generation was down 1.5 percent in 2017. Coal and natural gas declines were more than that with renewable energy projects coming online. Energy efficiency has made a difference! Another article reported that some utilities are planning for the uptick in electric vehicles to cause the trend in electricity generation to turn upward again. Right now – it seems like people that buy electric cars are often the same people that install solar panels; that could result in no uptick to the draw from the electric utility.

The Life Issue | WIRED – A collection of thought provoking articles about ‘what it means to live in an age of improvisation.’ I started with the articles about the 55-infinity age group.

Microscopic Images of Seeds • Insteading – hmm…maybe I’ll take a magnified look at seeds before I plant them in my flower beds.

Meditate regularly for an improved attention span in old age – Nice to know that something enjoyable immediately is also good for the long term too!

Photobook Captures Diverse Beauty of 100 Different Types of Chickens – Who knew there were so many kinds of chickens!

Some states now advocate coexistence with–rather than killing of–coyotes – National Geographic – We have an overpopulation of deer in our area…and we hear coyotes more frequently. The only time I’ve seen them is a blurring running away from me. I’m cheering them on this spring; maybe they will help limit the size of the deer population.

BBC - Future - Why being a loner may be good for your health – Being alone is not the same as being lonely!

Strange and Unbelievable Facts About Shrews – Cool Green Science – I’ve never seen a shrew – or maybe I just didn’t realize what I was seeing. Watch the 2 videos!
