Zooming – July 2016

Instead of making collages from clips of images – I’m doing Zooming past the 30x my camera will do with its lens. It will do up to 120x although it is essentially in-camera cropping because it is utilizing the resolution of the sensor rather than the lens. At 120x the images sometimes begin to look like an impressionist painting with a softer focus – but they can also show a lot more detail than the eye can see. It is easier to get good results with a monopod (I dislike the bulk of a tripod although I might try it more frequently. I picked 8 of my favorite zoomed images from the past few weeks.

I like to be well back from insects so that my camera does not influence their behavior. I once had a praying mantis jump on my camera! So using the zoom to capture the milkweed tussock moth caterpillars was my preference. They are about only about a half inch long.

Reaching back into the overgrowth along a path if often not a good idea: too many plants with thorns (like these wine berries) and poison ivy. Standing back and using the zoom to get the picture is the way to go!

I didn’t want to chance getting the web these caterpillars were creating on the front of my camera by getting close…and zooming worked very well.

I’m sure this bug would have flown away if I’d tries to get close. I also like that the background is still there but out of focus. The flower is chicory; it was about the same diameter as a quarter.

Aphids! The white ones are an earlier stage than the yellow ones. They do move around so zooming rather than getting close is my preference.

This seed stalk of a pokeweed was back in the waste high brush – glad I didn’t have to push my way thought it to get this image. I liked the pink and green. Later the seeds will be a deep purple.

This tiger swallowtail is enjoying a nectar snack! He would have flown away had I been close at all.

This is a max zoom photograph of a swallowtail wings. There is a fine line between nature photography and abstract art!

Ten Days of Little Celebrations – July 2016

Our July has been hot….a very summery month. My celebrations included.

Fireworks – but on July 9^th rather than on the 4^th. It was just when our local community held their event. We did buy a watermelon to enjoy on the 4^th of July – a typical food for summer celebrations.

“The Mother Nature” Award – I was so pleased to be recognized by the Howard County Conservancy for my volunteering with them. The contents of the goody bag (artisan bread and strawberry jam) was part of my little celebrations for about a week!

Photography with campers -  I’ve just finished 2 days of nature photography sessions with campers aged 5-12…and I am celebrating their photographs. I’m glad I’ve made it through the 2 very hot days too. Blog posts about the experience to come in the next few weeks.

Green Heron – I always celebrate seeing a bird in the wild that I don’t see very often…the green heron at Kenilworth is a good example. It was certainly the highpoint of that visit to the gardens.

Butterfly outreach – I volunteered to assist with butterfly outreach to 4 Montessori schools this month…one of which my daughter attended 20 years ago! I celebrated that the school is still going strong, much the same as it was when my daughter attended and the wonderful interaction with the children that are there now. They were all very interested in learning about butterflies.

Indoors, staying cool – We’ve had some very hot days recently and I celebrated most of them staying indoors with air conditioning – glad that I didn’t need to do anything outside!

Milkweed tussock caterpillars – Since I have quite a crop of these caterpillars at my house I have been able to photography them a lot this season. I’ll be doing an update soon since they are now even bigger than they were when I posted about them earlier this month.

Kitchen flooring – We have started the process to replace the flooring in our kitchen. It is 25 years old and needs to be done. I celebrated that my husband and I agreed easily on what we wanted and the materials have been ordered.

Carrot cake and Zucchini bread – This is two celebrations. I am using the bounty from my CSA to bake. I love having one of these for breakfast these days so the ‘celebration’ continues for more than just the day that I back. And I have bags of shredded zucchini in the freezer to make more!

Froghopper (spittlebug)

I’ve seen lots of froghoppers/spittlebugs (or the ‘spit’ from then); it turns out that the ‘spit’ if from the nymph stage of the insect so I had no idea what this pink and yellow bug was that I saw on the underside of a milkweed leaf. The skin it had just shed was underneath the bug…and it was about 1/3-inch long. All I thought initially was that it was a 'pretty bug.'

At first I thought it was a nymph of some kind but then I realized it had wings that just hadn’t dried enough to be fully recognizable. My son-in-law helped me identify it from the picture.

A day later I looked again and I think I found the same bug on the milkweed plant. It had moved from the underside of the leaf to the main stem was very still head down on the plant.

The old skin was still on the underside of the leaf (the yellow insect next to it is an aphid).

I wanted the insect spew tiny water droplets onto the adjacent leaf. Mature froghoppers still suck juices from plants but instead of making ‘spit’ it is tiny water droplets!

1980 Flooding in Plano TX

When we bought our first house in the late 1970s, we were told it was in a 100-year-flood-plain and we were required to have flood insurance. The closest we came to needing it during the 5 years we lived in the house was in 1980 – twice!

In the spring time, heavy rains caused the little stream in the park less than a block from our house to swell and overflow its bank. Water rich is sediment roared through the park scouring grassy slopes. Debris caught on trees that has been growing on the stream bank but were in the middle of the fast moving water during the flood.

The water covered the sidewalk and made the signage for the park look short. The area of houses across the park from where we lived was newer. I wonder now if the runoff was made worse by the increase in impervious surfaces with the new housing developments that were springing up all over the area.

In the fall there was another flood. We got out and drove around a little. Some roads were closed – but they were side roads rather than main thoroughfares. The water was not very deep (note the person walking out into the water on the left of the picture below.

The stream in the park near out house flooded again. As soon as it stopped raining – people in the neighborhood came out to take a look.

My husband also took a picture of the failing infrastructure that ran along the side of the stream. The flood water probably had more than just rain runoff in it; the sewer system was overwhelmed at least in some places.

In the time since 1980, that area of North Texas has continued to develop. The land is relatively flat so municipalities have made greenways with space to let water collect or channels to move water more quickly to places where it can collect. I’m glad my current house (in Maryland) is not in a flood plain!

Gleanings of the Week Ending July 23, 2016

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.

Microplastics – a cause for concern – Lots of questions…only a few answers. It seems like there have been a lot of articles on the topic recently.

Biodiversity has fallen below ‘safe’ levels – We don’t actually know what the ‘safe’ limit is…but do we want to actually find out when there is no recovery? This report is pointing out that 58% of the world’s land has lost more than 10% of its biodiversity. 10% biodiversity loss is the value that was deemed ‘safe’ limit within which ecological function is relatively unaffected.

Early preschool bedtimes cut risk of obesity later on – Another good reason for preschoolers to be regularly tucked into bed by 8 PM!

Electricity generated with water, salt and a 3-atoms-thick membrane –

Splattered Watercolor Paintings Capture the Beautiful Vibrancy of Delicate Flowers – I like just about everything botanical…eye candy too.

Jupiter and Juno – What do we already know about Jupiter’s chemistry? – An infographic from Compound Interest – background for understanding what we already know about Jupiter’s chemistry and what we hope to learn about it from Juno.

From the Earth’s Oceans (images) – From The Scientist. These images reminded me of how different live in the oceans really is than what we experience on land.

Photo of the Week (from The Prairie Ecologist) – Actually – several photos…of little things that thrive in the prairie.

How Type 2 Diabetes Affects the Brain – Two recent studies that have increased our understanding of the cognitive effects of diabetes – refining not only the description of effects but also how the structures of the brain are changed by diabetes.

Yeast emerges as hidden third partner in lichen symbiosis – Wow! This is something I’ll include in my talk with hikers about lichen. They are always fascinated that lichen grows on rocks and tree trunks….that it’s a combination of fungus and algae…and now we can add that there is usually a yeast there too that is often the part producing chemicals to defend the other two organisms in the symbiotic relationship (and sometimes it changes the appears of the lichen too)!

Photographs through a Window – July 2016

I stopped putting birdseed in our feeder in early July when one of the squirrels got coordinated enough to dump a little seed from it. It wasn’t happening consistently so the ‘squirrel proof’ was not filing totally but enough that I decided they didn’t need the extra food in the summer months. I still go quite a few birds to photograph through my office window. The parent of the juvenile house finches featured in yesterday’s post must have been the birds I saw most frequently around our deck.

This frazzled looking Carolina Wren might be a fledgling from the nest in an old gas grill.

Nuthatches always look alert when they are in their head-down stance. This one was enjoying the last seed I put in the feeder.

There is a male indigo bunting that I see periodically so it might be nesting nearby. I photographed the bird from my office window

Then went downstairs to get a different perspective through the French door in our breakfast area. The mourning dove provides a nice size contrast.

The juvenile cardinal still had some downy looking feathers on its breast and around its head

But its bill has turned the adult color over the past month.

I am keeping our bird bath full of fresh water so I expect that will be the reason birds will continue to visit our deck for the rest of the summer.

The bird on the right is making motions like a chick begging for food – but the one on the left does not look like they will be obliging!

Birds with Eyebrows/Horns

I was curious about some little birds that showed up near my window this month that seemed to have tufts of feathers that looked like eyebrows or horns. The lighting for the first picture I got was not that good – but did capture what I was seeing.

I did some research and discovered that they were juvenile house finches! They must have just recently fledged because there was usually a parent bird around when these birds with eyebrows came to our deck.

Sometimes the birds went into begging mode – probably hoping for a feeding from a parent…and sometimes they did not seem as adept at flying as the adult birds. They’ll gain flying skill and lose their eyebrows in a short time.

I’ve been thrilled to see more finches this year even before these fledged….and now there are apparently even more.

Green Heron at Kenilworth Gardens

Last weekend when we went to Kenilworth Park and Aquatic Gardens, I decided to walk out to the boardwalk rather than stay in the area around the lotus and water lily ponds --- and I found the high point of the visit in the wetlands beside the boardwalk. Not far from the boardwalk, on a partially submerged fallen tree, was a green heron fishing for breakfast.

When I first saw the bird there was another nearby that flew away…but this one stayed long enough for me to move around to get some of the twigs out of my line of sight to the bird.

I zoomed out to get more of the scene. The bird was catching tiny fish – moving so quickly that I didn’t quite capture an image of the fish before it was swallowed.

The bird moved and my line of sight was even better.

The bird is only about as big as a large robin but has much heavier legs and feet...and a longer beak.

And it even posed for a maximum zoomed portrait!

Eastern Painted Turtle at Kenilworth Gardens

On one of our visits to Kenilworth Park and Aquatic Gardens, there was a crowd around one of the ponds looking at – not lotuses or water lilies – but a turtle. I think a child had spotted it first but then everyone around looked too. It was surprising how difficult it was to see it in the pond. It was a rather small one and it was sitting in a puddle of water on a lily pad.

It seems more interested in the bees that were visiting a nearby flower than it was the people at the edge pf the pond.

I took enough pictures to identify it as a young Eastern Painted Turtle when I got home. On other visits we saw other turtles but they were in the water and not very photogenic. Maybe it was the season. We are past the time when the turtles need to sun on logs to get warm!

Charlottesville VA in 1980

I recently scanned pictures from a conference my husband went to at the University of Virginia in Charlottesville back in 1980. At the time, we didn’t even think about me accompanying him; I was working full time but we were both still in graduate school…and very conscious of living within our means. So – the one or two roles of film he took on the trip was the extent of my experience of the trip. I think my favorite image from the beginning was the oculus skylight from The Rotunda at the university. Evidently there was a tour offered to conference participant to Monticello as well.

The thing that I realized as I was looking more closely at these pictures was that we still take very similar pictures today but, because we don’t have to worry about the cost of film and its processing, we take many more images and probably try more experiments. Enjoy the slideshow of the University and Monticello in 1980!

I picture that my husband was surprised by was a picture of a Ryder truck that had gotten stuck under an overpass! It was with the pictures of Charlottesville so it was probably something he came upon as he was walking around the campus.

Ancient Brazilians occupied the same homes for centuries – Homes that were never abandoned…just extended with new floors on top of old ones, different types of ceramics and new building techniques.

Photography in the National Parks: Don’t Forget to Pack Your Flash or Reflector for Some Fill Light – This post shows images in bright sunlight with and without flash/reflector….a good ‘lesson’ in improving photos of flowers particularly.

Discover Your World with NOAA: An Activity Book – For kids and educators. The Earth Origami activity was one I looked at. This is quite a treasure trove of activities…all available online.

How to Raise Brilliant Children, According to Science – An interview with the author of Becoming Brilliant: What Science Tells Us About Raising Successful Children. She defines 6 Cs: collaboration, communication, content, critical thinking, creating innovation and confidence spread across 4 levels of development (summarized as seeing is believing, multiple points of view, opinions, and evidence/mastery/intricacies of doubt).

Professor finds positive effects for bringing physical activity to the desk – A positive link between mood, motivation and physical activity without detracting from work or study effectiveness…what’s not to like. For me – the Swopper chair seems to have these effects.

The People vs Coloring Books: The verdict is in – For children…the overall message may be to ‘step away from the coloring book’ and celebrate difference rather than conformity. When I was cleaning out my daughter’s papers from 1^st grade (over 20 years ago) I found a lot of lightly used coloring book type pages; it appears that she didn’t like them very much. She recognized them for what they were – busy work.

Incidence of cancer in patients with large colorectal polyps lower than previously thought – 92% of the colorectal patients referred for operation were noncancerous! My family had this experience and it is interesting to find out that it is not uncommon. Hopefully the more advanced endoscopic techniques can replace the traditional operation in some of these cases.

7 ways to find things to do in nature near you (US Edition) – Good ideas!

Butylparaben can have several endocrine disrupting effects – This is an ingredient (preservative) in many cosmetics and skin care products. Whatever testing was done in the past on the chemical probably did not even check for this kind of issue. And now we have a pervasive chemical that is impacting our biology in a negative way.

Insects in our Garden

A few days ago was out working in our garden by 7 AM – pulling weeds and cutting spent flower stalks in our flower beds…but I got sidetracked observing insects. The first I noticed were on the skeleton of a milkweed plant. The milkweed tussock caterpillars had eaten all the leaves leaving only the stem and the larger veins of the leaves. They had started crawling over to the bush next to the stem. It seemed like there were hundreds of caterpillars.

After I finished some work, I went inside to clean up and recover from heat. I started wondering if the caterpillars would find the other milkweed plants that were about 5 feet away from the one they had consumed. I went to check at 9 and they had indeed found another plant! I continued to check periodically throughout the day. The gradually spread to 3 more plants. Sometimes they would appear very active and other times they would be resting underneath a leave that was still whole. When they ate, individuals worked on the leaf from the top and the bottom. It was a mass feeding frenzy.

The next surprise came the following morning. I went outside and found that the caterpillars had been active overnight and seemed to be larger. When I went back to check an hour later – more than half of them were not anywhere on the milkweed and I watched as more of them dropped off the plants. It was time for them to go roaming in the leaf litter!

On one of the checks of the caterpillars, I noticed some insects on a blazing start that was in bloom. They were tiny – about a quarter inch. The yellow and black insect is a syrphid or hoverfly.

There were two other insects on the plant but they stayed down in the flowers so much that it was hard to get a good identification.

Maybe some kind of bee?

The two types of insects did interact a little…did not seem to like the other being nearby.

I was very pleased with the performance of my camera (Canon PowerShot SX710HS) and the monopod’s contribution to stabilizing the camera to get clear images.

Sunset…and then Fireworks

The fireworks nearest to where we live were on July 9^th rather than the 4^th. We headed out to the parking lot where my husband works since we knew it would not be crowded…and we’d viewed the fireworks from there in 2014. Unlike 2014 – we left the house early enough to get a parking place that was next to the curb so that we could get our lawn chairs out and unfolded onto the sidewalk by our car. I was using my usual Canon Powershot SX710HS. I put it on my monopod/walking stick and continued to sit comfortably during the whole event. It was a very relaxed photo shoot and I enjoyed the fireworks too because I could look over the top of my camera while they were happening.

The sunset was colorful. I took a few pictures about 10 minutes apart while families with children played on the grassy area that will become the location of a new building by next year.

The fireworks stared about 9:15 – just as it got dark enough. The images I’m including in this post were selected for a variety of reasons: streak of exuberant color,

Burst within burst,

Simplicity,

Red orbs,

Lots of complex structure….it seemed like there were more sequences like this that previous years,

Another complex sequence…and a smaller one below the main starburst,

Wow – I wondered how the fireworks were made that delivered this,

And this one too.

My husband has a more expensive camera and I picked some from his collections as well. I like the colors and the crisper images he was able to capture.

Going to fireworks that are close to home meant that we were home by 10!

Lotuses at Kenilworth Gardens

The lotuses at Kenilworth Park and Aquatic Gardens are in bloom in June and July each year. We’ve visited three times so far this year…and the lotuses were the most numerous and largest flowers of the place. They grow in shallow ponds and range in color from white to darker pink. The leaves are lived out of the water on stalks; the leaves are large and round with veins that radiate from the center.

The stalks that end in buds, flowers, or seed pods rise above the leave layer. The ponds contain many stages of lotus development during this season. Eventually – only the pods will remain.

I’ve organized some pictures to show the development toward seed pods….starting with buds and newly opened flowers. Dragon flies often alight on the tips of the buds – a good perch for them because of the small diameter and relative stability of the stalk in the breeze compared to the stalks with full flowers.

Then the flower is fully open and insects are frequent visitors. As long as the central portion is yellow – the flower has not yet been pollinated.

The flowers follow the sun. These are my favorite images of the flowers…when they glow with the sunlight through their petals.

Eventually the flower has been pollinated and the center part turns green and the rest of the flower begins to fall apart. This flower grew up into the lowest branches of a bald cypress.

The petals fall off and the seed pod is all that remains. The pods start to mature. They dry out as the seeds mature but none of them are at that stage yet this year. The petals last a little longer if they fall onto leaves rather than into the water but they decay very rapidly even on the leaves.

Most of the time the leaves are above the water forming shallow bowls that undulate in the breeze but there are exceptions. If they are on the water surface – they often have large beads of water that last much longer than dew on a summer day. They reminded me of glass pebbles used with flower arrangements or a form of abstract art.

The Grand Canyon in 1971 and 1983

I posted about our visit to Grand Canyon National Park back in January 2015. My scanning project has digitized the pictures I have from 2 earlier visits! The first was in March of 1971. The two pictures below were probably taken through a bus window.

We hiked down a little way down the Bright Angel Trail. The wind was cold and a light snow started to fall. You can see some of the accumulation in the rocks.

But the sun came out soon. I remember getting sand in my contact lenses (this was before the soft contact lenses were invented…so it hurt a lot) and being very teary eyed on the hike up because I was afraid the lenses would blow away if I tried to take them out.

Back at the rim – it’s easy to see that the clouds with the snow are moving away…and the dust on the color slide that I didn’t get off before I scanned it.

Skipped forward to late May of 1983 – we got up at dawn and caught the sunrise on the rocks.

We started early for a hike down to the plateau.

We could see the river soon enough.

See how brown the river looks? I looked up when the Glen Canyon Dam came online because I knew that when it did the sediment in the river was dramatically reduced...but discovered that it was completed in the 1960s. The Wikipedia entry did mention that in the spring and early summer of 1983 the water level in the dam was very high (and climbing) because of the runoff from the heavier than usual snow that fell the previous winter. The dam almost failed and a lot of water was being released…along with sediment...during the time we visited the Grand Canyon!

It appears that there were people on rafts in the river in 1983!

The path down is a lot of switch backs then a downward slope of the plateau.

We were walking but there were people on mules on the same trail - all the way down.

Looking up to the sky…..from inside the canyon...good memories.

Buttonbush – Pickerel Weed – Horse Nettle

There are other plants at Kenilworth Park and Aquatic Gardens besides water lilies and lotuses. Three that I noticed – and was pleased that I recognized – were buttonbush, pickerel weed, and horse nettle. The button bush grows at the edges of many of the ponds – often under a larger tree so that the bush is at least partially in the shade.

The flowers form round balls on the plant. They are green toward the center then white.

And the bees love them at certain stages of their bloom.

The pickerel week grows at the edge of ponds – in wetter ground that the button bush – and it likes full sun.

The arrow shaped leaves point upward.

The flowers start blooming at the bottom and move up to the tip of the stem….keeping the bees happy for the duration.

I spotted horse nettle near the ponds as well. This is a weed that is native…and very common to our area. It grows in our front flower bed (where I promptly pull it up) and in the meadow at the Howard County Conservancy. During the fall hikes the children always comment about this plant’s yellow fruits that look like tomatoes….and I tell them right away that they may look like tomatoes but they are definitely not tomatoes; the fruits are poisonous.

Kenilworth Water Lilies

The two dominate plants at Kenilworth Park and Aquatic Gardens during June and July are the water lilies and the lotuses. The sign for the visitor center has a water lily design. The flowers rest at almost the same level as the leaves very near the water surface while the lotuses are above the water – the leaves being a layer that flutters below the flowers that are higher still. I like photographing water lilies – particularly ones that have a lot of color and the background is dark enough to set off the color.

I always wonder what causes the plants to grow only in part of a pond. Perhaps it has to do with water depth.

During our visit in late June there were quite a few geese in one of the ponds that was filled completely with water lilies. They moved through the heavy foliage. They just swim through the foliage and the plants close behind the big birds. I zoomed in (series below) to get a closer look at the geese and noticed that some were juveniles – just beginning to get their adult markings.

As usual – I looked particularly to find flowers that be being visited by bees. Do you think these two bees are the same kind of bee? The lighting makes it hard to tell.

Dragonflies at Kenilworth Gardens

Kenilworth Park and Aquatic Gardens in June and July is my favorite place to practice photographing dragonflies. We’ve been twice so far this year and seen at least three different kinds. There are the ones that are powder blue with green eyes – their wings almost clear.

There are darker ones – that look almost black….and their eyes are glossy black.

Last but not least, are the ones with black and white markings on their wings. There were not as many specimens of this particular kind so I only got two pictures.

All of the swoop among the lotus flowers and buds – alighting long enough for photographers. I captured all the above pictures with my Canon PowerShot SX710 HS…. attached to a monopod. I wanted to capture some of them dragging their abdomens in the water laying eggs…but didn’t see any so far. There were some that were defending territory; there was some noisy mid-air collisions!

Spent Lotus Flowers

We are making weekly jaunts to Kenilworth Park & Aquatic Gardens since the later part of June. The lotuses and water lilies are in bloom during this time. It’s a good place for photography projects. One of my experiments the last time we went was to capture recently jettisoned flower parts on the big round leaves. I liked the colors – white, yellow, green…and occasional tinge of pink – and the curves. The first on I photographed still had water droplets left from the rain during the night.

The petals don’t last long once they fall. This one was a little past its prime but I liked the curves at the attachment end of the petals and the undulation of the leaf.

Sometimes they curve back onto themselves. The edges furthest from the attachment end of these petals have a tinge of pink…and the veins of the leaf under them seem to be radiating from the petal-as-sculpture.

Sometimes other parts of the flower spill onto the leaves while the larger petals slide down into the water below.

This leave held almost an entire flower with the petals turned in different ways. The pink edge shows on one of them. The veins of the leaf underneath don’t look as straight as when seen from the top.

I wondered how the flower parts came to be arranged. These seem neatly stacked!

I have a series of posts planned with images from the aquatic gardens...so stay tuned for lotuses, dragon flies, water lilies, and other things observed at this special place.

Washington DC in the Early 1980s

We moved to the Washington DC area in summer of 1983. I recently scanned the slides from those first few years and thought I’d post them on the 4^th of July since there are so many celebrations of our national history in the city. We made a house hunting trip in March 1983 and took time out to do a little sightseeing. The best pictures are of the capitol,

The National Gallery of Art,

And the Supreme Court building.

Thirteen months later (April 1984), my parents came for a visit. My favorite pictures from that visit are of the Lincoln Memorial

And the Einstein statue (with my mother in the picture holding a deciduous magnolia blossom that she picked up from the ground nearby).

In August 1984, we evidently made the trek into the city at night. The pictures my husband took of the monuments were quite good: The Lincoln Memorial,

The Washington Monument, and

The White House.

And then from the top of the Washington Monument: The White House,

The Jefferson Memorial, and

The Capitol.

I know that we made the effort to see the fireworks from The (Smithsonian) Mall at least twice during the subsequent years of the 1980s but I haven’t found any slides from those visits. I’ll save them for the next 4^th of July!
