Patuxent Research Refuge – Milkweed and Goldenrod

/

The milkweeds are going to seed and the goldenrods are blooming at the South Tract of Patuxent Research Refuge last week – typical fall meadow views. The milkweed seed pods have burst open and are spilling their seeds to the wind. The seeds have the possibility of starting new stands of the plant next year. The stands that are healthy now will come up from the roots already well-established next spring (i.e. no seed sprouting required).

My favorite picture of the morning was the very first one I took – with the dew still sparkling on the fluff and the seeds still neatly emerging from the opening pod.

Often the goldenrod and milkweed are mixed in meadow areas but there are some almost pure stands of the goldenrod. It is the hero in the fall for migrating Monarchs and other nectar feeding insects. Sometimes the plant gets blamed for allergies, but it is insect pollinated, rather than wind. People with fall allergies are more likely to be feeling the impact of ragweed pollen!

Patuxent Research Refuge – Waterlilies

/

Last week, my husband and I spent a morning at the South Tract of Patuxent Research Refuge. It’s about 30 minutes from where we live. The weather was a sunny and cool – typical early fall and a great time to be out and about.…and there were waterlilies blooming!

The first ones I noticed were in an area where the water level had recently dropped, based on the number of lilypads that were out of the water rather than floating. There was also a lot more vegetation in the water in that area other that water lilies.

Toward the end of our walk, we were between two ponds and the light was right for reflections. I liked the light pink of this first flower…even though a lilypad bisected the reflection.

The next flower I photographed I remembered to apply the rule of thirds after I took the first image….and have to admit – I like the second one better!

The visitor center was open but we didn’t go in. We’ll be back to see fall foliage in a few weeks!

Near the Little Patuxent River

/

On a recent morning – I headed out to the stream that flows under Broken Land Parkway from Lake Elkhorn just before it joins the Little Patuxent River for a volunteer gig – guiding a stream survey done by high school students. Near the bridge that crosses the stream on the Patuxent Branch Trail, there was muddy trail (poison ivy on each side…glad I had on long pants and high boots) to allow access down to stream. We set up our gear around three tables. There was not much dry area to set them up but the water was shallow. A partner and I guided 10 students to collect and ID macroinvertebrates from one of the tables while other volunteers did the same at two others. We had about 45 minutes….and then we got another group of 10 to do it again.

I took some pictures before and after the students arrived. The steam has a lot of vegetation on the banks but the stream has been eroded  - with some trees toppling over from being undercut by rapidly moving water. It is in an area where there is a lot of impervious surface. When it rains – the water rushes down to the stream where it carries away anything in the eroded channel; there is no connection to a flood plain that to slow down the water. It doesn’t take long for it to run off further downstream because we are in the Pediment rather than the Coastal Plain (i.e. there is always an incline for the water to follow).

The water quality was ‘very poor’ based on the types of macroinvertebrates that we found…however – we found quite a few of the types we found. The stream is not dead. Life holds on tight in this suburban stream.

Red Bellied Woodpecker

/

There is a male red bellied woodpecker frequenting our bird feeder. He assertive and noisy…and very picky about the kind of seed he wants. The mix in the feeder right now does not have as many peanuts as our previous mix – which, in the past, has been the favorite of these larger woodpeckers. The bird seems to do its most effective probing with its head upside down (the bird is heavy enough that it partially shuts the seed openings of squirrel proof feeder).

The bright red swipe on the top of the bird’s head makes ID easy. The most zoomed images show how the texture changes closer to the bill (maybe shorter red feathers there?). These birds use the back part of their body to help hold their weight while they hug the feeder like a tree!

Our birdfeeder cam has broken so these images are all taken with a camera and shot through the window of my upstairs office. I have the camera set to take multiple images if I continue to hold down the shutter button.

Gleanings of the Week Ending October 2, 2021

/

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.

The oil-field ‘fugitive’ that can slip into the water supply – The methane leaks into ground water are yet another reason fossil fuel is problematic. The industry evidently can’t or won’t clean up…making moving away from fossil fuels as quickly as possible even more urgent – although climate change should be enough for the world to be doing that already.

Top 25 birds of the week: Brown Birds – Not all birds are colorful! Watching small brown birds can be just as much fun though.

Ancient Human Presence Revealed At White Sands National Park - Researchers Push Back Date Of Human Arrival In North America Thousands Of Years – Fossilized footprints in the gypsum sand playa deposits…dated to the Late Pleistocene.

Mexico’s Ancient Inhabitants Moved Land and Bent Rivers to Build Teotihuacán – Still more being learned from an archaeological site that has been studied for many decades. LiDAR is one of new technologies that is yields a lot of new information.

Poorly circulated room air raises potential exposure to contaminants by up to six times – COVID has prompted more detailed research on this topic…and the discoveries should be used to improve building ventilation systems to help control other air-borne diseases.

Why colorful food is good for you – I like the colors and flavors….it’s an added benefit that they are also healthy choices!

NASA’s James Webb Space Telescope Will Launch Into Orbit in December – Finally!

River research reveals scale of macroplastic pollution – A plastic bottle takes a long time to break down….450 years and requires UV light. With so many bottles getting into rivers around the world, it is important to understand how they travel…how they begin to breakdown. They are going to be around for a very long time and, right now, more are still entering the rivers.

Research shows more people living in floodplains – From NASA. Tragedies that are getting worse as population increases and climate change causes flood risk changes.

Making Beetles Pee Can Protect Your Garden – Maybe this is also a pathway to an effective way to control insects like aphids without pesticides!

Zentangle® – September 2021

/

In recently months I have produced a lot of Zentangle tiles….not in September. I needed 30 to meet normal the one-a-day goal; there were only 39 to choose from rather than averaging 2+ tiles per day as in previous months. I put away my white highlight pen for the month as a challenge and discovered that I miss it too much; I’ll be using it again in the October tiles!

The September tiles were dominated by rectangles…only two squares during the entire month!

Studio International

/

I browsed 51 volumes of the Studio International magazines published from 1896 to 1922 over the past month or so. It was a time when the world was changing rapidly – modernizing through industrialization and the World War I years with the 1918 flu overlaying on that challenge. The volumes between 1917 and 1922 are missing. The 1920s were a frenzy of new fashions and cultural shifts. The magazines are a contemporaneous perspective of the time.  

I selected an image from each volume I browsed which are in the grid below – time sequenced; I selected color images but there are more that are pencil sketches or black/white photographs…and more architecture. The volumes are well worth browsing; links to the volumes are below the grid of images. To enlarge any image below, clink on the image in the grid.

Going to Seed

/

This time of year, the plants are going to seed. I walked around our yard finding a few:

A dandelion puff in the grass – not a many as in the warm days of late spring and early summer…once the dandelion crescendo they continue flowering and making seed puffs through the warm months until frost.

2021 09 IMG_9108 (1).jpg

Many of the ferns have spores on the back of their leaves.

2021 09 IMG_9108 (2).jpg

Coneflowers look almost threatening with the spikes of seeds….a drape of drying petals below.

2021 09 IMG_9108 (3).jpg

We had a pyracantha at one corner of our house when we move here over 25 years ago – it died back but has now come up from the roots and has orange berries again this year – a pop of color beneath the huge bush growing above the re-emerging pyracantha.

The allium in the chaos garden has green seedpods. They’ll take a little longer to dry and pop open to let the black seeds escape.

Zooming – September 2021

/

The joys of a camera with optical zoom (rather than a phone with just digital zoom) --- I see more detail through the camera than I can see with my eyes! There were several times I was out and about looking for opportunities for high key and pushing the limits of the optics. Several of those experiments were successful enough to be included in this month’s collection.

Enjoy the slideshow for the September zoomed images!

Ten Little Celebrations – September 2021

/

Celebrating the waning of summer…the beginning of fall –

Brookside Gardens field trip. Spending a few hours at Brookside always results in at least one mini-celebrations. This month there were three: hummingbirds – bees – and roses.

New low weight for the year. With a whole month at home, I managed to control my diet….and achieved a low weight for the year --- 3 times (lower each time). I’m celebrating the achievement and working to continue the trend!

Easy flu shot. I celebrated how easy getting the flu shot was…no waiting, the pharmacy already having all my information.  And now I’m as protected as I can be for my next road trip.

Macro photography. Celebrating images capture with my phone, a clip on lens and a clicker!

Melons. The season for melons was winding down but we celebrated 2 tasty cantaloupes from the Farmers Market in September.

Early morning in the grocery store. I enjoy grocery shopping….and celebrate that I have the store almost to myself…a low risk return to ‘normal.’

Volunteering. Returning to volunteer gigs – doing outdoor programs with students.. it’s another celebration of going back to a pre-pandemic ‘normal’ that isn’t quite the same but just as satisfying.

Beautiful weather. Sunny days…cooler…a little breeze – this is the time of year that it gets easier to celebrate a day outdoors.

Ferns under the deck. I celebrated that there were more of them than I expected this year!

French fries. I have been dieting so carefully….it was a celebration to have French fries (and cut back enough on other foods that day to not make it a “weight gain” day)!

Schoolyard Volunteering

/

I volunteered for a pilot program about climate change concepts (carbon capture, water infiltration, urban heat island) for 6th graders held on their own school grounds. It was a positive learning experience for me…and the students as well. Howard County Conservancy held training beforehand so when the first one was held I was relatively well prepared….but the first time through is always tricky. My station was about carbon sequestration; the students measured the circumference of trees on their schoolyard to estimate the weight of carbon in the tree and the weight of CO2 absorbed by the tree. The students became more coordinated with the process as they measured more trees:  using a tape measure - 137 cm up from the ground and then measuring the circumference. Teams of 3 worked well (2 for the tape measure and one recording results). Then in the last part of the session we use a table to determine the carbon in and absorbed by the trees.

The second school was an earlier start…out of the house at 7 AM! It was also a cooler day (in the 60s and lower 70s) so more comfortable wearing a mask. The students are mostly too young to be vaccinated yet. I took a quick picture of my front flower bed and the morning sky before I left the house.

My first assignment was carbon sequestration for 2 student periods and then water infiltration for the next three periods of the day. Many of the trees we measured were about the same size – probably planted when the school was built. We learned that even the grassy areas of school yards don’t have good water infiltration – maybe because the mowers used on them are heavy enough to compact the soil! And even the water retention ponds (which were dry during the session) did not let the water soak in. The mulched areas under the trees were the only areas that showed good infiltration. Most of the rain that falls simply runs off rather than soaking in close to where it falls.

There was some break time between periods, and I observed some sparrows taking dust bathes in a bare spot near the edge of the school ground.

20210921_104829.jpg

Overall – the students seemed to enjoy the program and collected data that they will use in their classrooms. I had my best experiences ever with this age group. Middle school is such a mix of student maturities…but the small groups made it relatively easy to engage all of them and keep them focused on collecting information about their school yard in a consistent, organized way. My lesson learned was that signing up for the full 5 periods is a bit overwhelming…probably won’t do that again!

Gleanings of the Week Ending September 25, 2021

/

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.

Top 25 birds of the week: September 2021 – Such a variety of birds in the world!

The Love Stories of Sleepy Lizards – An Australian lizard…they are monogamous and have a surprising threat display. They have been studied for over 40 years.

Searching for the Fisher Kings – The Calusa of south Florida…a capital on a man-made island made of shell. Surviving the Spanish but not the British.

New Coal Plants Dwindle Amid Wave of Cancelled Projects – Good! We need to be ramping up generation of electricity with renewables….and dramatically reducing the methane released by the oil and gas industry in their extraction processes…and then begin to reduce our need for oil and gas in areas that can be electrified (like transportation and heating/cooling).

Explore Life Under the Microscope with the Winners of the Nikon Small World Photomicrography Contest – Photomicrography frequently creates art from reality that it too small for our eyes to see without the magnification and specialized equipment.

August 2021 global climate summary – From NOAA. Two global maps (temperature and precipitation). Where I live, August was hotter and slightly wetter than the average (averages from 1981-2010 for temperature…from 1979-2020 for precipitation).

People synchronize heart rates while listening to stories – Thinking about the brain as part of physical body….looking at the brain-body connection more broadly.

Study Links Transportation Noise to High Rates of Dementia and Alzheimer's – From Denmark.

Indigenous Resilience Center Launched at the University of Arizona – My daughter did her graduate work at University of Arizona; I’m glad they are launching the center to find and implement culturally appropriate solutions to the challenges of climate change.

The chemistry of dahlia flower colors – Also explains why there are no blue dahlias.

Designs of Kyoto: a collection of design for silk and cotton textiles

/

The two volumes of Designs of Kyoto: a collection of designs for silk and cotton textiles (volume 1 and volume 2) were published in 1906 and are available on Internet Archive. I’ve selected 2 sample images from both volumes.

I enjoyed the books – lots of nature themes and ideas for Zentangle patterns. Some of them looked very abstract – geometric – hits of realism. There is a modern quality to many even though they are more than 100 years old. Maybe nature images are timeless as long as the animal/plant depicted still exists in our world.

Silk and cotton are luxuries now – the inexpensive fabrics are synthetic creating a lot of ‘fast fashion’ with interesting fabric patterns….like these.

Our Oak

/

Looking up into our oak that grows near our mailbox, it looks like fall is well underway. The flags left from the periodic cicada larvae this summer have dropped their leaves and the rest of the leaves are turning now too. I’ll need to do a round of mowing soon to keep the leaves from getting too thick on the grass. The Virginia Creeper has grown a lot this year…reaching higher into the tree than ever before. It’s a native and climbs with suckers rather than rootlets; it only damages the tree if it gets too heavy; right now, it is well within the range that the tree can handle.

20210919_072944.jpg

That’s not to say that the tree is in great shape. Oak decline is happening all over the Mid-Atlantic. There are stressors are thought to weaken the trees: climate change, tree age, site conditions, history of disease. Our tree is probably 30-40 years old (the house is about 30 years old but the tree was planted as a sapling)…not very old for an oak. There is pavement on two sides of the tree (the street and our driveway) so soil compaction might be a problem. It has always had mulch and grass around its base and there are no exposed roots.

The stressors might have weakened our tree enough to make it vulnerable.  The way some of the leaves look is indicative of Bacterial Leaf Scorch. It will be years before the tree succumbs – finally starving (i.e. leaves turning brown and falling early…not continuing to produce food for the tree during the entire growing season). We’ll shore up its defenses by watering it during drought…keeping the fallen branches and debris picked up around its base. And eventually cutting the Virginia Creeper.

High Key at Conowingo

/

On Sunday morning we left our house about 7:30 AM to drive to Conowingo – about a 1.5 hour drive from where we live. Below the dam is our favorite place to see bald eagles. This is not the best time of year, but it was a sunny fall morning – a good time for a short daytrip.  

There were some black vultures on top of a car parked near the entrance gate at Conowingo Fisherman’s Park. I had heard about it happening but hadn’t see it before. There didn’t seem to be many photographers along the fence however there were cormorants and gulls over and on the water. There were more cars than usual but apparently the owners were mostly there for fishing. We saw several with very large catfish (looked like the invasive flathead catfish). The spillways on the far side of the dam were active…but it didn’t seem like there was much water churn on our side of the river.

20210919_085324.jpg

I had just started surveying the abutment, rocks and island with my bridge camera mounted on a monopod, when the battery connection problem that I had experienced previously began. I had to take the camera off the monopod and remove the foot to open the battery compartment and try to increase the thickness of the paper wedge I had been using to hold the battery more firmly on the contacts. I put everything back together and it still didn’t work consistently. I was able to see an adult bald eagle on the abutment and a great blue heron on a spit of rocks and gulls flying over the water --- but the camera would not work for long enough to get a good picture. So – I gave up and pulled out my small Point and Shoot (Canon Powershot SX730 HS). I was very disappointed in what I could do with less zoom than the bridge camera. So --- I opted to try some high key pictures. My first subject was large sycamore with branches that hang over the water. The color variation in the leaves was more visible with the background mostly bright white although I did one with the water partially visible.

My favorite is the one below with the foliage in the lower right corner. I can image this in a presentation with some words in the upper left!

2021 09 IMG_5244 (6).jpg

Next --- I chose to photograph the electrical towers. I was not aware of the blue (vignetting) in the upper corners until I looked at it on the monitor at home….but I like the little bit of color!

2021 09 IMG_5244 (4).jpg

One of the towers on the island in the river contained a surprise that I didn’t see until it was on the larger screen: a bald eagle standing on a nest! It is not a good eagle shot…the bird is facing away and blurry….too far away for the Point and Shoot to get a crisp image. But it shows how the eagles use of the manmade structures!

Overall – I was pleased with the morning…even though it was quite different than I’d planned!

Annual Flu Vaccine

/

It’s that time of year again – time to get the annual flu vaccine. This year it was very easy for me; I went to my grocery store pharmacy just as I did last year… right after they opened. There was no line, and their system already had all my information. I filled out a form on a clip board, provided an electronic signature, and got the shot.

20210915_101148.jpg

I refrained from buying myself a treat like a piece of cake or a soft drink -went to the nearby thrift store instead. I found 2 pairs of ‘like new’ leggings that are easy additions to my fall wardrobe!

I am still planning another road trip to Texas in October so getting the flu shot in September means it will be fully effective by then. I am hopeful that the high rate of infection and hospitalization along my route will be reduced by then – and that hospitals will not be as overwhelmed as they are right now…just in case some accident occurs along the way.  

On the same day I got the flu shot – we had a very hazy day in Maryland and it was attributed to the California wildfires. Signs of climate change are everywhere. For me – getting the flu shot is an action to avoid a health issue at a time when the pandemic and climate change are straining the resources of our country to deal with those disasters – making it even more challenging to take the strategic actions to reduce and mitigate the climate change going forward.

Rough Green Snake

/

My son-in-law saw (and photographed) a rough green snake while he was hiking at Ritter Springs State Park near Springfield, Missouri. What a wonderful color! His picture prompted me to do a search to identify it…learn more about the snake.

Avery Resized_20210908_152014.jpeg.jpg

The highpoints of what I found: They are exploited by the pet trade – and people that want to keep them as pets (I’d rather they stay in the wild!). The snake eats insects and other small invertebrates - spends most of its time in trees, often near water. Not venomous. Their range evidently extends into the area where I live in Maryland, but I’ve never seen one. I’m going to start looking for them. It would be quite a thrill to see them in the wild.

Not long after I received the picture, there was a blog post from DFW Urban Wildlife that included some pictures of a rough green snake in Texas! It contained some other critters that are hard to spot in the wild. I am going to look more closely for them…hone my observation skill. It’s probably true that there is almost always more to see out in nature than we notice!

Macros – September 2021

/

My smartphone, a clip on macro lens, and Bluetooth shutter control were the gear I used for the macro photos feathered in this month’s post. They are all from a short walk in Howard County Conservancy’s Mt Pleasant from the parking area and into the Honors Garden. The set up works very much like the bridge camera (with lens, diffuser, manual focus) in that I must get close to the subject and move the phone to get the focus perfect. It has the advantage of being a lot more compact than the other set up!

The rain from the night before had left everything with a sheen or droplets of water. Often the wet increased the richness of the colors…and the shine. The thin clouds provided good, diffuse light – a good day for smartphone macro photography. The cedar was on my way to honors garden.

20210909_090222.jpg

The seed pods on the magnolia were not flat enough to be an easy shot! The depth of field is very narrow with magnification.

I experimented with different perspectives of cone flowers

And asters. In the last picture, the depth of field gave me the blurring around the edges than I wanted.

20210909_113756.jpg

The birds nest fungus was in a mulched area near the parking lot. Some of the cups seem to hold water!

20210909_091438 clip.jpg

Even grass seeds take on a different perspective in a zoomed image.

…And these are the best of the rest (note the insect hiding inside a flower)!

Gleanings of the Week Ending September 18, 2021

/

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.

Young female black bears in Asheville, North Carolina, are big, have cubs early – More research needed…it’s still not known what is causing them to be so much bigger and mature early…or if the population is increasing or not. It is clear that there are quite a few bears and lots of opportunity for interactions between people and bears – many not healthy for the bears.

The alarming risks of mixing common drugs – It is a problem that is acute in most elderly patients with good medical care. Their various doctors have gradually built up the medications…and the regime to take them all appropriately becomes daunting. Hopefully it will become best practice to constantly review and minimize drugs that are prescribed.

Work Of First African American Painter With International Reputation Explored – Henry Ossawa Tanner (1859-1937)

Hummingbirds can smell their way out of danger – I was thinking a lot about hummingbirds this past week after my success photographing one at Brookside Gardens.

Praying Mantis – I see these more frequently in the fall…but not every fall. There are so many mantis egg cases, there should be plenty to see; I need to improve my observation skills.

How much energy do we need to achieve a decent life for all? – The most important take away from this study: “energy for eradicating poverty does not pose a threat for mitigating climate change.” That is good news

The lost generation of ancient trees – The ancients are dying….and there are not enough trees old enough to replace them. There are various ways being tried to veteranize younger trees so they can play the role of ancient trees in ecosystems.

Fall Armyworms are Attacking Lawns and Crops on an ‘Unprecedented’ Scale – Hmmm…maybe this is a prompt to reduce or eliminate the grassy portion of the yard.

Mammoth Cave National Park: The World's Longest Cave Is Longer Than Before - 8 more miles mapped bringing the total to 420 miles!

Hand pollination of crops is of major importance – I was surprised that hand pollination is already used for important crops like apple, palm oil and cocoa.

Arts and Decoration from 1920s and 1930s

/

Over the past couple of months – I browsed through 29 volumes of the Arts and Decoration Magazine from the 1920s and 1930s. There are a few color images – dominated by covers and ads. I enjoyed thinking about the history and mood of the times reflected in these periodicals.

In the 1920s – Some company names we still see today show up – Davey Tree Surgeons, Listerine, Armstrong Floors, Heinz, Lincoln, Cadillac; some ads for companies that no longer exist too: Quaker Lace Company, Oil-o-matic Heat, Insulite, Johns-Manville Asbestos Shingles. The depictions of women were changing just as the clothes they were wearing: less constrained. The magazine reflected the quickening pace and almost euphoric mood of the decade. 1923 (vol 18-19), 1923 (vol 19-20), 1924 (vol 20-21), 1924 (vol 21-22), 1925 (vol 22-23), 1925 (vol 23-24), 1926 (vol 24-25), 1926 (vol 25-26), 1927 (vol 26-27), 1927 (vol 27-28), 1928 (vol 28-29), 1928 (vol 29-30), 1929 (vol 30-31), 1929 (vol 31-32)

And then came the crash in the 1930s. The volumes from the 1930s contain less color – except for the covers. Most advertisers were weathering the Great Depression but not paying for color ads – except for Kenwood Blankets and a steamship company. The magazine was depicting the perspective of the wealthy but even they were not as flamboyant and exuberant as in the earlier decade. This was the decade when my parents were born. They were far from scenes depicted in the magazine…living in the middle of the US in rural areas where they had plenty of food their parents grew on their farms. 1930(vol 32-33), 1930(vol 33-34), 1931(vol 34-35), 1931(vol 35-36), 1932(vol 36-37), 1932(vol 37-38), 1933(vol 38-39), 1933(vol 39-40), 1934(vol 40-41), 1934(vol 41-42), 1935(vol 42-43), 1935(vol 43-44), 1936(vol 44-45), 1936(vol 45-46), 1937(vol 44-47)

Browsing magazines is a perspective of the important things of the day – carefully selected by editors to present to their subscribers. It reflects a narrow perspective – probably: wealthy, white, skewed to the east and west coasts. It would be interesting to know the demographics of the subscribers but maybe even the publishes didn’t know that!
