Frustrated Squirrel

/

The squirrels in our yard attempt to get seed from our bird feeder periodically. Sometimes I watch them from my office window and wonder whether it is the same squirrel or different animals each time. They always leave frustrated unless they manage to tilt the feeder enough as they are jumping off to spill some seed to the deck below. That happens infrequently. When it does, the amount of seed is only a small snack for the squirrel.

Recently the bird feeder cam captured a frustrated squirrel. It started out reaching for the feeder as if it had figured out that the contraption would make the seed unavailable once it was touched. The squirrel made the leap…thoroughly explored the feeder from every orientation while it was swinging wildly as the squirrel moved around. The whole of the action took place in 3.5 minutes. And the squirrel left without a morsel. It interesting to notice the squirrel’s tail being curled as it finished the leap off the feeder….then straight out as it heads down and away from the feeder. Use the arrows to move back and forth in the sequence.

I’ve been reading about Salmonella transmission through bird feeders and baths. We haven’t found any dead birds and we’ve been more careful about keeping both clean….washing our hands after handling  them since there are some cases of transmission to humans too. My plan is to finish the bag of seed we have then take the feeder down this summer. It easier to keep the bird bath clean (and we check it frequently to avoid it fostering mosquito larvae). There’s enough seed to keep the feeder going during spring migration – which we’ll do unless we see dead birds.

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.

New wearable device turns the body into a battery -- ScienceDaily – I’m always forgetting to charge my Fitbit until the low battery warning message comes up. It would be great to never need to charge it!

Soot from Asia travels express on a highway to the high Arctic : Research Highlights – Soot in the Arctic traced back to its source.

Working outdoors linked to lower risk of breast cancer among older women -- ScienceDaily - Outdoor workers are able to make more vitamin D which may be protective, say researchers. This is an observation…but might indicate a thread for future research.

World's first dinosaur preserved sitting on nest of eggs with fossilized babies – An fossilized Oviraptorosaur, a bird-like theropod, found on a nest filled with its 24 eggs.

Stealth Chemicals: A Call to Action on a Threat to Human Fertility - Yale E360 and Air pollution: The silent killer called PM 2.5 -- ScienceDaily – Products of human ingenuity that are negatively impacting our health.

94% of older adults prescribed drugs that raise risk of falling: From 1999-2017, more than 7.8 billion fall-risk-increasing drugs were prescribed to older adults in the US, and deaths from falls doubled -- ScienceDaily – In my 50s, my doctor prescribed a blood pressure medication that made me dizzy. When I complained about it (citing the danger of becoming dizzy and falling down stairs being a greater risk than the benefit of lowering my blood pressure to the level she was attempting), she decided I didn’t need the medication since I was taking half the lowest dose tablet. I hope that the medical professionals prescribing the fall-risk-increasing drugs are more careful about how they are using them now for older people particularly…but for younger people too. Sometimes it seems like the trend is to always ‘treat with drugs’ to address a specific problem rather than integrating for the overall health of the individual.

Was This Helmet Worn by an Ancient Greek Soldier During the Persian Wars? | Smart News | Smithsonian Magazine – Found by a dredging vessel off the coast of Haifa, Israel.

50 Birds: Adventures in Backyard Birding – Birding can be done anywhere. Many people have discovered the joy of bird watching from home during this pandemic year.

Joshua Trees: An Uncertain Future For A Mojave Desert Icon – A big fire and climate change….are the Joshua Trees doomed?

Health declining in Gen X and Gen Y, US study shows -- ScienceDaily – The long-term trends are not positive; the US was already seeing decreases in life expectancy and increases in disability/morbidity pre-pandemic. The study pointed to the increase in unhealthy behaviors over the past decades that medical treatment cannot overcome. Based on the response to public health measures attempted in the US for the pandemic, it’s difficult to be optimistic that any kind of intervention could be broadly effective.

eBotanical Prints – March 2021

I finished browsing the rest of the Arnoldia volumes (from the Arnold Arboretum) available via Internet Archive in March; there are 24 of them. Sometimes the volumes are a single issue…sometimes groups of issues (not always divided on year boundaries). I am looking forward to the variety of botanical prints that are not from a series in April!

The whole list of 2,108 eBooks can be accessed here.

Click an any sample images below to get an enlarged version. Note that Arnoldia sometimes includes articles on historical botanical illustrations…sometimes includes traditional botanical drawings…and a lot of photography. Enjoy the March eBotanical Prints!

House & Garden Gleanings

/

I have finally browsed all the House & Garden magazines I found on Internet Archive…from 1901 to 1993! I started back in November 2020….and browsed one or two of the volumes on most days. This post is the grand finale from the volumes I browsed through in 2021 – featuring a few items that caught my attention from the 1940s onward that I haven’t already featured in a blog post (previous posts: Newport Teahouse and Green Animals on 3/12,  The White House in 1940 on 1/21, House & Garden Magazines on 12/16/2020).

In the volume from the second half of 1941 – a page of old-fashioned Christmas tree decorations. I was surprised that the paper chains that I made in the 1960s had been around since at least the 1940s!

18 21 01 (39).jpg

The cover of the volume from the first half of 1942 featured “Planning a Defense Garden” – a reminder of the impact of World War II.

20 21 01 (1).jpg

In the volume from the second half of 1962 – pictures of the White House. I would have been in the second grade.

There were two things I’m highlighting from the volume from the first half of 1970.

55 21 02 (1).jpg

The first is an advertisement for a ceramic stove top. It was the first time I’d seen one in the magazine. It took a long time for the technology to mature!

55 21 02 (26).jpg

The second is a story from the Ladew Topiary Garden. We went several times when my daughter was young in the early 1990s since it is not far from Baltimore.

In the second half of 1971 volume – there is an ad for a Sears lamps that my parents bought (the chain and table versions) and gave to us a few years later. We donated them sometime in the mid-1980s.

67 21 02 (14).jpg

There was an article about the White House (again) in early 1973. This was about the time I got married.

Longwood Gardens was in the Christmas issue in 1977. This was years before I visited the gardens.

In the volume from the middle of 1985, there was an article about Mount Vernon. We had moved to the Washington DC area in 1983 and Mount Vernon was one of our favorite places to take family members that came to visit.

In the fall of 1986, the magazine had an article about Dumbarton Oaks. My husband and I were attending some Smithsonian Associates programs around that time and Dumbarton Oaks was one of the places we toured. I remember it was the first place I saw a black squirrel.

In early 1987, the magazine had some pictures from Winchester Mystery House in San Jose, CA. We had friends that lived in the area that we visited about that time, but I never toured the house until 20 years later when I was there for work and had an afternoon on my own.

There were repeats of locations too – Mount Vernon again in 1989

And Ladew Topiary again in 1992 (which might have been close to the time we took my daughter as a toddler).

There was an article about Monticello in 1993.

Overall – I enjoyed browsing all the magazines….a little history…reminders of places I’d been…ideas for what I might do in my own home (or not).

Hugh Thomson – Illustrator

/

I noticed Hugh Thomson’s work when I was browsing the Stephen Lucious Gwynn books about Ireland and did a broad search for other books he illustrated. He was an Irish illustrator best know for pen-and-ink illustrations. I browsed 5 books with his illustrations back in February published between 1895 and 1913; I’ve selected at sample image from each one.

The Story of Rosina and other Verses (1895)

66 21 02 (1).jpg
74 21 02 (10).jpg
98 21 02 (7).jpg
103 21 02 (3).jpg

Two historical reflections:

  • Do you prefer the pen-and-ink or the color illustrations? Today we are so bombarded with colorful illustrations/photographs that we tend to expect color…..but the pen-and- ink show a different kind of detail.

  • Based on the Wikipedia entry, Thomson died in 1920 at 59 years old. His career as an illustrator declined with World War I and he was forced to find other work during the last years of his life. I wonder how many people will find the COVID-19 pandemic as disruptive to their livelihood/life plan as previous generations found the World Wars.

As I was writing this blog post, I noticed that the Wikipedia entry for Thomson has a list of selected works that includes links to Internet Archive. Some of the books do not list Thomson in their metadata (i.e. the illustrator was not listed along with the text’s author) so I didn’t find them in my broad search. Hurray! I have some additional Thomson illustrated books to browse!

Reflections on the Mt Pleasant Farmhouse

/

Last time I walked around Howard County Conservancy’s Mt Pleasant, I started thinking about the changes around the front of the farmhouse since I first saw it back in fall of 2013. The large tulip poplar in front of the house had already been cut down; over the years I noticed the increased weathering of the stump and its roots have decomposed too. It’s a favorite place to find snake skins and sometimes small snakes…spiders…ants!

The stump to the left was cut closer to the ground in the past few years after the tree started dropping branches and there was concern about potential damage to the farmhouse. I remember a hike with kindergarteners when the tree was still there – me standing about 6 feet away from the trunk of the tree…facing the children and their chaperones a little further from the tree…talking about what might live in the tree….they were talking about the birds and the squirrels…I turned around to gesture to the tree….and there at about eye level was a large black rat snake. What I great teaching moment! I pointed the snake out to the group. The chaperones took a few steps back; the children stayed put at rapt attention. We talked about why the snake might want to be in the tree as it slowly moved from its spot of sunshine on the trunk slithering underneath the loose bark until it was out of sight. Later, after the tree was cut down, some groups tried to count tree rings…others used the spot for a group picture.

The walk up to the front door was added in the year before the pandemic. The front porch is often used as a stop for the younger elementary school hikes and most groups were taking various routes over the grass to get there prior to the construction of the walk. The porch is particularly welcome on rainy days. On one such day before the walk was built, my group made it to the porch as the last stop before lunch; as we turned to go…it started raining even harder; we waited for a few minutes, but it didn’t let up and everyone was hungry. We eventually left the haven of the porch and splashed through puddles toward the nature center building – the revised picnic lunch location.

On the far right…across the gravel drive there is another stump. It was a silver maple that was planted in the later 1800s (based on the tree ring count). It was cut down a before the walk was built There was a ‘twin’ silver maple on the other side of the circular drive what was cut down at the same time (hidden by the cedars on the left in the pictures). The stump on the right was sanded and some steps cut into the side so that the kindergarteners could climb up to see (and count) the tree rings.

My history with the house is a few short years. The house has a longer history with the façade mostly from after the Civil War and there is a log cabin of even earlier vintage enclosed by the additions and modifications made to the house over the years. It’s interesting to think about the highs and lows of the family that lived there…the ways they used the spaces…made changes to fit their needs…the technology incorporated over the years (plumbing and electricity, for example). My few years are a short window into the house’s history!

Racoon at our Feeder

/

Our squirrel-proof bird feeder has been mostly effective against squirrels and racoons. Recently we had our first bird feeder camera recording of a racoon that managed to get seed…for a max of 13 seconds! All the other the racoon visits the animal has gone away totally frustrated.  This time the racoon managed to support most of its weight on the frame of the deck rather than the feeder for those crucial seconds. As soon as the animal grabbed the feeder with both paws….the spring stretched enough to close the access to seed.

Clips of the whole sequence are below. Use the arrows to move back and forth and see the black metal leaf close down over the access hole for the seed as the racoon puts both paws onto the feeder.

Newport Teahouse and Green Animals

/

The issues of House & Garden from the second half of 1983 (available on Internet Archive) include pictures from two Newport RI places that I visited back in 2014…and I always like to find places I’ve visited in magazine pages:

Green Animals Topiary Garden (my blog post from October 2014 and the official site). It was one of my favorite places because it was outdoors…and so different from the ostentatious houses.

t 19a 21 03.jpg

Chinese Teahouse at Marble House

(the official site and my blog post with depictions of the Tea House published in the 1916 Architectural Record that includes some of my photos from 2014). I only saw the outside in 2014 so it was interesting to see the picture of inside from 1983 and the ‘Votes for Women’ cup from its association with the suffrage movement.

Another significance for these issues – my husband and I had just made our big move from Texas to the east coast (Virginia) in 1983. We had moved into our house at the end of June and within a couple of weeks, the air conditioner compressor stopped working! As I browsed through the 1214 pages of this volume, I remembered that I would have been way too busy to have noticed them at all in 1983 (unless they happened to be available to thumb through while I was waiting for an appointment). Here are some other images from the volume that I am enjoying so many years later!

Zooming - February 2021

/

As I selected the images to include in this monthly post, I found more variety than usual. The experimental high key images are quite different than my usual photography – a type of photography I will continue to use in otherwise poor lighting conditions. There was also a lot of snow….in landscapes and as background to the usual birds. I took more pictures of deer in February too. One subject carried over from last month – the skunk cabbage is still blooming at Howard County Conservancy’s Mt Pleasant and it’s the only picture taken away from home! Enjoy the slideshow.

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: Bird Interactions! - Wild Bird Revolution and Top 25 birds of the week: Raptors!  and Top 25 birds of the week: Feathers!  – A treat this week – 75 bird photographs – enjoy!

The unseen 'slow violence' that affects millions - BBC Future – The harms that happen so slowly that we don’t notice in the moment. It happens over months and years and decades (maybe even centuries). We notice as we use our ‘big data’ to see hot spots of ill-health, where the environmental degradation is at it’s worst, and populations that can’t seem to escape their dire situation. And the issue very quickly becomes – how does our culture respond to the awareness of that ‘slow violence.’

Carbon: Getting to net zero -- and even net negative -- is surprisingly feasible, and affordable -- ScienceDaily – A detailed model of the entire US energy and industrial system….showing how to achieve carbon neutrality by 2050…with particular emphasis on what needs to happen in the next 10 years.

The country rejecting throwaway culture - BBC Future – France has introduced an index of ‘repairability’ rating for appliances…hoping to increase the electronics repair rate to 60% within 5 years. I’m glad I opted to repair my clothes drier rather than replace it….although the repair (replacing of the failed heating element) produced some trash it was a lot less than the whole appliance! Things like phones and laptops and monitors are harder.

Carolina Wrens Will Nest in Just About Anything and Why Carolina Wrens Have Moved into Your Neighborhood – We had a Carolina Wren make a nest in a gas grill we hadn’t used in along time. It surprised me when I opened the lid and the bird – startled and then panicked – flew out onto the deck railing. There is usually a pair nesting somewhere around our yard; we see them when they come to the feeder and hear them even more frequently. The forest behind our house and the brush pile at the edge of the forest are good places for them.

Federal Funding Obtained to Replace Zion National Park's Shuttle Fleet – And they’ll be electric! What a great way to keep the air smelling like nature rather than combustion fumes!

Rare Yellow Penguin Photographed for the First Time | Smart News Science | Smithsonian Magazine – What an unusual looking bird! It’s a king penguin on South Georgia Island with leucism, a condition where melanin is only partially lost and some parts of the body retain color. In this case…the ability to produce the usual black pigment is missing.

New River Gorge is America's Newest National Park - News | Planetizen – This park is within ‘road trip’ distance from where we live….maybe a destination post-pandemic.

How we turned a golf course into a haven for rare newts, frogs and toads – Hopefully US golf courses are doing things like this too. I usually think of them as using a lot of chemicals and would not want to live near a golf course….but if they consciously made places for amphibians….it would mean that other creatures could survive in the space too. There is an Audubon International Certification program for golf courses but they don’t publish a list of course that are certified.

The Arctic Ocean might have been filled with freshwater during ice ages – Based on a geochemical study of sediments.

Japan in old Books

/

The ‘subject’ metadata in Internet Archive can be used to find clusters of books on the same topic. Earlier this year I used a simple search to look at books about Japan using the subject “Japan – Description and Travel” and then sorting by the date published since I was mostly interested in books old enough for the copyright to be expired. I browsed the search results for books that included illustrations and am featuring my favorite ‘finds’ from this search in this weeks’ book post.

Every-day Japan by Arthur Lloyd (1909)

17 21 01 (27).jpg

Since my success with books about Japan – I’ve used the same type search for China, Algeria, Peru, Sweden, and Ireland….and am now browsing books from the Greece version of the search! I enjoy exploring books in the Internet Archive using the digital equivalent of walking through the stacks of a library…selecting a book and leafing through its pages (using thumbnail views)…pausing when something looks interesting. The big difference is the huge number of books available via Internet Archive and that I can do it anywhere/anytime there is a good internet connection! What a boon it is….particularly during this pandemic year.

New Swopper Chair

/

My Swopper chair, that was more than a decade old, broke back in December; the base separated from the pedestal and seat. It could function as a stool that could tilt but had lost connection to the mechanism that enabled the bouncing motion. The new limitation impacted my goal to keep my activity level up all during the day (i.e. minimize completely sedentary time). I tried to shift to a new activity pattern; moving was more clumped than before because it included getting up from my computer to move every hour then having some times that were completely sedentary except some side to side moving on the broken Swopper. I found that I sometimes felt achy even after 30 or 40 minutes of not moving! The Swopper chair had allowed me to move more frequently without breaking my activity at the computer without me even being conscious I was moving…and I opted to buy a new Swopper.

Now my office is back to the old ‘normal’ with the new chair and my aches are dramatically reduced.

The chair comes in 3 pieces in a big box: the base, the pedestal with spring, and the seat. Once they are put together…they don’t come apart. Its are expensive but will last a long time. I figure I bounced more than a million times on the old one before it broke, and I hope this new one is a durable.

Staying active every day is a lifestyle choice….one that helps me sustain the ability to do things I want to do for as long as possible.

Stephen Lucius Gwynn Books about Ireland

/

I’ve enjoyed 5 books with pictures of Ireland published in the same decade as World War I. The author – Stephen Lucius Gwynn – was an Irish MP and writer with close links to the Iris literary revival; he had a long and varied career (I always browse the Wikipedia entry for the authors/illustrators of books I enjoy).  These books were illustrated by Irish illustrators of the time; many are in color; I selected one or two for each book. I find the illustrations of this period – just before color photography took over for books like this – very appealing. They capture the places as they were…also representing the history of book illustration.  

The Famous Cities of Ireland (1915) with illustrations by Hugh Thomson

Leinster (1911) with illustrations by Alexander Williams

The Fair Hills of Ireland (1914) with illustrations by Hugh Thomson

Munster (1912) with illustrations by Alexander Williams

Ulster (1911) with illustrations by Alexander Williams

It is interesting to think about the time it took to produce these illustrations compared to photography. Do as many people make their living as artists today?

Technology has changed our work and the way we live in so many ways. I’ve changed almost entirely from physical to digital books over the past decade! I don’t need to go anywhere to obtain my books these days and there is always a huge number of books readily available to me. I find myself savoring the illustrations – painting and photographs - in books/website more than ever. What a boon during this pandemic year!

Snowflakes (melting)

/

Trying to photograph snowflakes when the temperatures is in the low 30s is hard. The snowflakes clump as they fall with the temperature that high…and then the melt very easily even if the surfaces and equipment is cooled to ambient temperatures. I’d gathered all my usual equipment: phone (with a clicker to control the shutter on a lanyard) and clip on 65x magnifying lens (with light)…and was quickly frustrated with not very satisfying images toward my goal of photographing individual flakes.

So – I changed the goal and opted to create a series of a clump melting. I did several series and the one below is my favorite. It takes place over only 34 seconds!

Just before I went inside, managed to photograph some spheres on the sleeve if my coat. The magnification shows the black fibers of the coat. I think the spheres were ice (micro hail stones!) and the second one appears to have some crystalline structure inside…maybe a fracture.

Using frustration over a goal that has become impossible to prompt innovation/creativity is probably one of the best resilience strategies of all.

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.

Self-controlled children tend to be healthier middle-aged adults -- ScienceDaily – Benefits include younger brains and bodies, better outlook in the years ahead. This finding is from a study done in New Zealand with 1,000 people tracked from age 3 to 45 (i.e. they were born in 1972 and 1973). Hopefully they will continue to be tracked as they get older….to determine if they remain healthier as they age. The finding makes sense to me based on my observations of my own life and people I have known over many years.

An Invasive Wild Edible Winter Rose – Natural History Society of Maryland – Multiflora rose…it’s a plant that takes over – climbing over everything around it…and it is prickly. One redeeming quality might be the RoseHips that can be used to make tea. Birds eat them too and that propagates the plant – so maybe more harvesting by humans would reduce this invasive!

College campuses are COVID-19 superspreaders, new study suggests -- ScienceDaily – My daughter and son-in-law are very aware that this could happen at the university where they teach and have research teams. They are offering blended classes so that students can be in person or virtual…and providing higher quality masks for their themselves and their research teams.

The 'megascale' structures that humans could one day build - BBC Future – Some history and observations…the realization that there are existing ‘megascale’ structures: terracing of parts of Southeast Asia, land reclamation from the sea by the Netherlands, the internet, the US Interstate Highway system.

SolarEV City concept: Building the next urban power and mobility systems: Unlocking the potentials of EV batteries with roof-top PVs for urban decarbonization -- ScienceDaily – Calculations done for 9 Japanese urban areas…CO2 emissions in these urban areas could be reduced by 53-95%!

The state of the climate in 2021 - BBC Future – Looking at CO2, record heat, Arctic ice, permafrost, and forests. We need to make progress toward drawdown rather than continuing actions that cause the upward ramp of planetary warming.

Are monarchs in trouble? | Science – In my area of Maryland…the decline has been dramatic.

A Tweak to Immune Cells Reverses Aging in Mice | The Scientist Magazine® - Interesting but so far has not be translated into humans. Evidently a drug to specifically block the EP2 receptor is not easily developed.

Tiny hard drives that are alive — and multiplying : Research Highlights – Experiments with data encoding in the E. coli genome. Evidently the data is protected from degradation in the presence of dirt and other contaminants…but what about changes that would occur over many replications?

Top 25 birds of the week: February 2021 – A grand finale to the gleanings….bird photographs!
