Zentangle® - February 2020

/

29 days in February 2020….so that’s the number of Zentangles I select from the pile I created during the month. The black background tiles are from the iPad (in the Procreate app); I opted to not carry pens and paper tiles when I traveled during the first part of the month so all the tiles from February 1st through 9th were on the iPad. I did a series using letters as strings. A few of them made it into the picks for the month.

Toward the end of the month, I was experimenting with mono-patterned tiles without a frame or string.

And then there were the rest….

3 Free eBooks – February 2020

Three picks from my February browsing in Internet Archive…..so many books to choose from.

Richardson, Frederick (illustrator). Old, old tales retold - the best-beloved folk stories for children. Chicago and New York: M. AAA. Donohue & Company. 1923. Available from Internet Archive here. I wonder how many children in the 1920s had access to books like this one. My guess is that the books were mostly available in cities and to wealthier families.  There is a Wikipedia entry for Frederick Richardson that prompts me to look for other books that he illustrated. The metadata for books on Internet Archive does not always list the illustrator….so searching by title or the author of the text is required.

Vermont Department of Tourism and Marketing. Vermont Life. Montpelier: Agency of Development and Community Affairs. A quarterly magazine published from 1946 – 2018…all available from Internet Archive here. I started out with the first issues and am now up to 2004. It is interesting to see how the state changed over that time. I enjoy all the seasons but picked a ‘spring’ picture since that is the season coming up.

Scott, Jeffries, Samantha (editor). Homes & Antiques. Immediate Media Company Bristol Limited. A magazine with most issues from January 2015-March 2016 available from Internet Archive here. There were several pictures with shoes stored under the bed. Now I don’t feel as guilty about not putting my shoes in the closet floor as we did when I was growing up. At least half my shoes are by the door to outside or under my computer desk!

Top 25 Wild Bird Photographs of the Week: February 2020 – Note the new website for these weekly posts: https://wildbirdrevolution.org/ ---The posts are still the beautiful bird pictures collected into a group for a weekly visual celebration of birds.

100% Wind, Water, & Solar Energy Can & Should Be the Goal, Costs Less | CleanTechnica – A short summary of a report with specifics for 143 countries…getting to 80% renewable energy by 2030 and completing the transition by 2050. Now to vote with that goal in mind for a livable future for ourselves, our children, our grandchildren….and onward.

LEDs, Downward Lights Changing the Night in Chicago - News | Planetizen – Chicago will complete the transition to energy efficient LED streetlights in 2021. They’ve calculated that it will save the city $100 million over 10 years. At the same time, they have made an effort to focus the new lights downward to cut light pollution. It’s too early to tell if that aspect of the project will be a success.

Vegetation Filters Harmful Particulates from Air--But How Much? | The Scientist Magazine® - It’s probably better to push for the transition to renewable energy (in school buses, for example) but where that is not happening fast enough – planting a green wall of vegetation can block pollution from school yards…which could reduce the impact of vehicle exhaust on children’s lungs.

Decline in Coal-Fired Power Reduces U.S. Carbon Emissions in 2019 - News | Planetizen – Good news…but it could decline more quickly. The 2019 results are from market forces alone. If there were political will, things would happen even faster.

Archaeologists Excavate 200 More Chinese Terracotta Warriors | Smart News | Smithsonian Magazine – The first terracotta warriors were found in China’s Shaanxi province in 1974. Now there is more excavation and more soldiers from the same tomb. All the warriors have unique expressions, hairstyle and physical features.

Organic crop practices affect long-term soil health -- ScienceDaily – This study looked closely at organisms in the soils…along with the impact of prior soil disturbance.

Recovery: A Plague of Bullfrogs – The Eastern part of the US is the native range for Bullfrogs…but they are invaders in the West. They are clearing native frogs and eating other animals too (ducklings are an example cited). So various municipalities and conservation groups are acting.

What We Can Learn From Ötzi the Iceman's Hunting Pack | Smart News | Smithsonian Magazine – Ötzi was preserved for 5,300 years in a glacier until he was discovered in 1991. A lot has been studied since that time. He’s a window into Copper Age Europe.

Photography in the National Parks – More favorite spots for photography from Rebecca Larson. This collection included three National Parks I have not visited: Glacier, Olympic and Mount Rainier. Now I want to plan a trip to see them!

All About Feathers – A tutorial on feathers…lots of great visuals (stills, videos, drawings, photos) from The Cornell Lab Bird Academy.

NOAA Research’ top 5 stories from 2019 – Catching up on some reading…the stories featured were the most popular on their site in 2019.

Capturing CO2 from trucks and reducing their emissions by 90% -- ScienceDaily – Research applicable to making transportation friendlier to the environment…retrofitting of existing trucks.

Rising Temperatures Are Stressing the U.S. Corn Belt - Yale E360 – It’s not just rising temperatures…it’s the shift in rainfall causing hydrologic stress during the summer months. Maybe the ‘corn belt’ could shift northward?

Traveler Special Report: Threatened and Endangered National Parks – In Alaska and beyond…we are losing the natural treasures we sought to protect.

The history of candy canes and why they taste so cool – I am late getting around to including this in the gleanings list. I like peppermint candy year round…even if it’s not in the candy cane shape! I have peppermint candy chips to use in snow ice cream…if it will ever snow enough this winter here in Maryland!

Largest Electric School Bus Program in United States Launching in Virginia | CleanTechnica – Dominion Energy partnering with Virginia School districts…to achieve a 50% electric school bus fleet by 2025 and 100% by 2030. Good for the environment and the lungs of Virginia’s school children. I hope other states will move in the same direction.

These infrared images show just how alive butterflies’ wings are – Surprise! Butterfly wings have living cells not just membranes and scales! The living cells can sense heat and the butterfly responds behaviorally.

 Flame retardants and pesticides overtake heavy metals as biggest contributors to IQ loss - ScienceDaily – There are a lot of things that are toxic in our environment these days…and children are the ones that are hurt the most…and the hurt lasts their lifetime. This study looked specifically at lead, mercury, poly-bromated diphenyl ethers (PDBE…flame retardants) and organophosphate pesticides.

Abstract Aerial Photos of Iceland's Rivers Look Like Watercolor Paintings – A little art photography to start out the gleanings this week.

Tomb Containing Three Generations of Warrior Women Unearthed in Russia | Smart News | Smithsonian Magazine – Evidently research is revealing that warrior women were the norm, not the exception, in Scythian culture. Scythians lived in small tribes, wore trousers (practical since they were on horseback much of the time) and fought with bows and arrows.

Protecting the Sonoran Pronghorn from Extinction – It’s complicated….lots of agencies involved….an international border that is becoming a migration barrier.

Is Notre-Dame Too Fragile to Be Saved? | Smart News | Smithsonian Magazine – Removing the scaffolding that was melted by the fire is evidently going to be a big challenge.

Whooping cough evolving into a superbug -- ScienceDaily – The research was done in Australia…but it probably applies to the US as well. Bottom line: we need to be developing an improved whooping cough vaccine.

One Reason Colorado Playgrounds Are Looking Way More ‘Natural’ | Colorado Public Radio – I like the new types of playgrounds….more than swing sets and slides…bringing in some natural elements.

White Sands National Monument Redesignated As A "National Park" – A beautiful and unique place. I’ve only been there once…but it was very memorable. The biggest surprise for me was that even on a hot day in June, the sand was not hot! Being white really does reflect the heat up and away.

2019 Year In Review: Some Great Photo Tips – So many beautiful places to photograph….take some time in a natural place (National Parks are awesome…but there are other places that are great too).

Striking Portraits of Rare and Endangered Birds by Tim Flach – I tend to like bird pictures from the wild…but these are amazing portraits. Virginia Cardinal – I was surprised to see it in this grouping…as far as I know they are not different than the Northern Cardinal. Cornell’s Allaboutbirds doesn’t have a listing for them.

Mealworms safely consume toxic additive-containing plastic -- ScienceDaily – Not an answer to the plastic problem…more like basic research that could be incorporated into a partial solution. The biggest gain comes from dramatically reducing single use plastics.

Zentangle® - January 2020

/

31 Zentangle tiles for January…and only 2 were made on the iPad using the Procreate app. I was in the mood to make tiles on paper with pens, I guess. It wasn’t a conscious decision. I used different colors of tiles and tried some experiments before my Zentangle session with the Howard County Conservancy volunteers…hence the gingo and beautyberry patterns showing up more frequently. I didn’t use a singe round tile in January --- leaning toward something different after all the round ones I made in December for the Christmas tree. Next month it will probably be more balanced between paper and digital tiles since I will be doing some traveling and the iPad is often already in my hands (since it also provides my reading material).

Unusual Urban Bobcat Spotted in Washington, D.C. | Smart News | Smithsonian Magazine – Wow! There is more open area where I live (between Washington DC and Baltimore)…maybe there is a bobcat around here too.

Low doses of radiation used in medical imaging lead to mutations in cell cultures -- ScienceDaily - Discovery that radiation creates breaks that allow in foreign DNA must be confirmed in animal studies. Maybe this is just a pathway to learning more about how cells cope with natural amounts of DNA damage….or maybe we need to look again at the risk/benefit of some routine diagnostic testing.

Stunning Chronophotos of Powerful Osprey in Mid-Hunt – Very dramatic!

Surprising Beauty Found in Bacterial Cultures – The video is less than a minute…worth watching.

Top 25 Wild Bird Photographs of the Week: #Feeding – National Geographic Society Newsroom – They all must eat. I kept track of what they were eating in the pictures: snail, insect or other small invertebrate, frog, rodent, fish, lizard, algae, carrion, nectar, skink, or seeds.

Walnuts may be good for the gut and help promote heart health -- ScienceDaily – I like walnuts….now just to eat them more consistently!

HEADING TO THE FOREST: Bringing Joy, Accomplishment & Hope to Children | Children & Nature Network – Forest days for kindergarteners and nature kids from preschool to high school…backyard to back country. More examples of how education in nature is happening. This was part 2…the earlier article can be found here.

America's most widely consumed oil causes genetic changes in the brain: Soybean oil linked to metabolic and neurological changes in mice -- ScienceDaily – Start reading labels….there is soybean oil is in a lot of processed foods like mayonnaise and salad dressings….the list goes on and on. Evidently other soy products (edamame, soymilk, tofu, etc.) don’t cause the same changes observed with soy oil.

Blue Jay: A New Look at a Common Feeder Bird – Our feeder is not accessible to blue jays….but we see them at our birdbath frequently….and hear their calls in the forest and our yard trees.

Macro Photography Shows Stunning Details of Carnivorous Plants – Some botanical pictures to finish out the gleanings for this week.

3 Free eBooks – January 2020

/

Starting out the new year…I selected 3 books with an art and history skew from my accumulation of reading this month.

14d 20 01.jpg

Dillon, Edward. Glass. New York: G. P. Putnam’s Sons. London: Methuen and Co. 1907. Available from Project Gutenberg here. The book is a history of glass (up until the early 1900s) with illustrations of pieces in museum collections. I paid more attention to the illustrations than the text. I’ve always been interested in ancient glass because it points to the step beyond basketry and pottery in our manufacturing expertise. It a material we think about as being ‘breakable’ but is often very enduring.

21l 20 01.jpg

Whitney, Frederick. Blackboard Sketching. Springfield, Massachusetts: Milton Bradley Company. 1909. Available from Internet Archive here. Written at a time when many students were learning to write and draw with blackboard slates and slate pencils…it provides an idea of how students were taught. Early classrooms used a lot less paper!

LaFontaine, Bruce. Bridges of the World Coloring Book. Dover Publication. 1994. Available from Internet Archive here. The bridges are organized chronologically. The sample image I show below is the colored version (as the end page of the book) of page 10…a bridge from China built about 1100. The book includes short descriptions the design features and technologies the bridge builders utilized. Obviously, these bridges have proven to be very durable.

Top 25 Wild Bird Photographs of the Week: January 2020 – Starting out with wild and wonderful birds this week.

Infographic: How does nature influence human health? – Most people intuitively know that nature has a positive impact…but now there is more and more research to quantify that impact.

The Plastics Pipeline: A Surge of New Production Is on the Way - Yale E360 – Just when I really want manufacturers to find ways to package products in something other than plastic….the industry has plans to ramp up production of plastic. Consumers can still make a difference with our purchases (or lack of purchase). I’m slowly but surely reducing the items I buy that come in plastic….always looking for alternatives.

New aqueous lithium-ion battery improves safety without sacrificing performance: Non-flammable, cost-efficient, and effective battery -- ScienceDaily – Hurray for all the battery research going on right now….hopefully there will be more and better options near term. It would certainly boost the speed we can transition away from fossil fuels.

Pylos Tomb Artifacts Suggest Trade Links - Archaeology Magazine – Amber from the Baltics, imported carnelian, pendant depicting an Egyptian goddess….the Greek site might have been a stop on a trade route.

Happy New Year from Amundsen-Scott South Pole Station – Kelly Brunt posted this on January 3rd….and I just got around to looking at it. She was one of our hosts at NASA for my HoLLIE class and then the keynote for our graduation. It was good to read about her recent activities!

Super Resilient Protein Structures Preserved a Chunk of Brain for 2,600 Years – Wow – what an amazing and surprising find! And there is has been some research to figure out how it managed to be preserved.

Towards Ecophilia: Being hopeful in spite of it all -I enjoyed the pictures and activity descriptions about children in nature.

How US sewage plants can remove medications from waste-water – Using granular activated carbon and ozonation….more than 95% of certain antidepressants and antibiotics can be removed. This is important to help reduce the development of antibiotic resistant bacteria and maybe other environmental harms as well. But it can be expensive.

The oldest person in the world turns 117 – I liked the last paragraph of the story the best: Last year, when Tanaka received her record for the world’s oldest person, she was asked about the happiest moment in her long life. Her reply was simple: “Now.” Wouldn’t it be great if we all could feel like that no matter how old we are!

In the Middle Patuxent River – January 2020

/

Last week I was in the Middle Patuxent River at Robinson Nature Center for the quarterly (winter) water monitoring. The temperature was in the 50s and sunny – an easier sampling than most years. I always like to take some pictures from right at or in the river. It’s a different perspective that being on a forest or meadow trail.

20200115_095557.jpg

I was the only one of the sampling crew with just boots….everyone else had waders. But the river level was not too high. I didn’t get water in my boots…and no one fell in either.

20200117_151004.jpg
20200115_095734.jpg

We caught a madtom (catfish) in one of the collection nets (collecting macroinvertebrates). We took pictures and let it go before we headed up the hill to the Nature Center.

In the lab, we divided the buckets of samples into plastic bins and we all started collecting macros from our bins and randomly putting them into the two partitioned trays.

20200115_120727.jpg

Then random numbers were drawn to determine the compartments we would id and count until we got to 100….and then we looked at what was left for anything unique. Almost everyone took a few pictures of macros. The most unique thing we found was a white worm!

This was the first time I participated in a winter monitoring and it might have spoiled me – being as warm as it was.

Reeve’s Conchologia iconica

/

I usually select three eBooks to feature in a monthly post…and I’ll do that in a week or so. Today I want to feature a series of books I found recently on Internet Archive: Conchologia iconica, or, Illustrations of the shells of molluscous animals by Lovell Augustus Reeve. There are 20 volumes (Vol v.01 (1843), Vol v.02 (1843), Vol v.03 (1845), Vol v.04 (1847), Vol v.05 (1849), Vol v.06 (1851), Vol v.07 (1854), Vol v.08 (1855), Vol v.09 (1856), Vol v.10 (1858), Vol v.11 (1859), Vol v.12 (1860), Vol v.13 (1862), Vol v.14 (1864), Vol v.15 (1866), Vol v.16 (1866), Vol v.17 (1870), Vol v.18 (1873), Vol v.19 (1874), and Vol v.20 (1878)) all published in the mid-1800s. The author died in 1865 and the series was continued by George Brettingham Sowerby. Soweby did the plates for most of the volumes. I found a reference about the books that said: It will always remain a standard work, although many of the species which Reeve created are now held to be invalid. That’s probably to be expected given the many years since they were published; science is always learning more. Still – the plates are beautiful and provide a broad view of the variety of shells known at the time. I collected one plate from each volume to use with this post.

The question that I wonder about is how many of the mollusks that produced these shells have gone extinct in the intervening years. How many types of shells represented in the books are no longer grown? The International Union of Conservation of Nature lists 310 recently extinct species.

When the best way to take notes is by hand - BBC Future – I like to take notes by hand….it always seemed easier to me than using a laptop (although I tried using a laptop to take notes in meetings during my career). Now it seems that it is better for internalizing concepts too. No need for me to try to change to anything else!

Blue Whales’ Hearts Can Beat Exceptionally Slowly | The Scientist Magazine® - As low as 2 times per minute! The high was 37 beats per minute.

Image of the Day: Ochre Paint | The Scientist Magazine® - Evidently ancient people heated aquatic bacteria mats growing in iron rich water to make a bright red paint which was used for rock art. The paint contains microfossils of the bacteria (Leptothrix ochracea). The red color is highly thermo-stable…something that has applicability to manufacturing.

Crows could be the smartest animal other than primates - BBC Future – Clever crows. Not so long ago we thought humans were the only ones to make and use tools.

Future For Silversword Plants At Halaeakalā National Park Dark – Rare plants…have not recovered as well as the Nene (Hawaiian goose) – for several reasons. Plants around the world are having to adjust to changing climate and some will not be able to change fast enough to continue to exist in the same places…some may become extinct. I hope the Silversword survives.

Eastern Bluebird – January 2020

/

On the second day of the year, a male Eastern Bluebird appeared in our backyard. I saw him first near the bird bath. By the time I got my camera, the bird was in the sycamore…looking serious. It was a relatively cold day so the bird’s feathers were a little fluffed to provide more warmth; he looks very rounded.

I thought he had flown way but when I checked the videos from our birdfeeder, I found that the bird had attempted to visit the feeder….but headed to a perch was too high to get and seed. It quickly backed away and I didn’t see it again. Even though the clips from the Reolink video are a little blurry – it does show how the bird maneuvers to back away from the birdfeeder.

We don’t see bluebirds very often so this it was a pleasant surprise to see the bird. In January 2018, I managed to photograph 3 bluebirds at our birdbath!

Clearing damaged cells out of the body helps heal diabetics' blood vessels -- ScienceDaily – Interesting….but still a lot of research needed before it could potentialy be used in treatment.

The toxic killers in our air too small to see - BBC Future – Nanoparticles – 90% of particles by busy roads are nanoparticles below 100nm. The smaller the particles, the greater potential toxicity. Anything smaller than 30 nm can make it to through the lungs and into the blood stream (larger than that doesn’t gets past the lungs). The Global Burden of Diseases study estimates that air pollution could account for 21% of all deaths due to stroke and 24% of deaths from ischaemic heart disease.

Camera on the Birdfeeder – Setting Up

/

I posted some initial results of our bird feeder camera back in December. This post is a little more about our experience…now that we’ve settled on a configuration. The camera we are using is a Reolink Argus 2. In December, we were experimenting by using a ladder to temporarily mount it; our goal was to decide where to mount the camera and the best settings.

2019 12 IMG_6947.jpg

Our first attempt at more permanent mounting (and one that would not show in the pictures like the ladder did) was on a bracket just below the eave of the covered deck. We discovered almost immediately that the bracket was not as stable as we had thought it would be; a breeze could cause the camera to move. So – we started thinking through alternatives.

Even with a wobbly camera,  we did capture a good sequence of a male and female red-bellied woodpecker interaction at the feeder (the male is the one that has red from front of his head all the way back to where the black and white feathers begin). The female was there first but flew to the support for the covered deck when the male arrived – pecking the wood (in frustration?) then flying off.

Our next mounting scheme was to mount a board to the supports for the covered deck and then the camera with its solar panel on the borad.  So far it is working well. We’ve been tweaking some settings. I’ll post some results in a few days.

2019 12 IMG_7013.jpg

I use the Reolink Client on my PC to view the videos captured by the camera. I download the ones I want to clip for my blog – either as single images or a sequence of images. It’s been a lot of fun to watch the antics of birds that I didn’t catch from my office window. So far, we haven’t had any unexpected visitors…but I am enjoying the views of behaviors I would not have seen otherwise.

First Day of 2020

/

I got up early enough yesterday to see the sunrise. The clouds were too low and thick for it to be a great one…but it was the first of 2020. I did the same thing last year….with clouds making the color smudgy.

2020 01 IMG_2103 (23).jpg

We decided that the clouds were going to clear off enough to make a trek to Conowingo Dam to see the bald eagles worthwhile. It was a cold morning, so we wore snow pants and took hand warmers. As we drove in, I noticed the seagulls first; we hadn’t seen any gulls last time we went to Conowingo (in late October). As I got out of the car, I heard some eagles and saw one flying with a stick. It circled around and went up to the platform near the top of an electrical tower. I later zoomed in for a picture of the sticks accumulating for the nest. There was a nest there in previous years so the pair may just be adding new sticks…making sure the sides are high enough to contain the chicks until they are ready to fledge.

2020 01 IMG_2103 (1).jpg

The water was high from recent rains and the dam was generating power. Both gulls and eagles were benefiting from the fish available – stopped by the dam. We didn’t see any cormorants or great blue herons this time.

2020 01 IMG_2103 (3).jpg

The eagles were active but very far away on the rocks and abutment…swooping above and into the water for fish. It is very close to out of range for my camera so most of my pictures are a little blurry.

2020 01 IMG_2103 (2).jpg

There was an interaction between two birds on the abutment. They both looked rounded with their feathers fluffed and I wondered if it was from their ‘argument’ or just being cold.

Another interaction – two juveniles. One was on the rock but flew off just as the other came in for a landing.

Another juvenile was fishing…but didn’t manage to land a fish in this foray.

My husband’s camera did a bit better. He managed to photograph an adult catch a fish, jostle it into position, be chased by a juvenile…and then take the fish up to the nest. Was there a mate at the nest? We couldn’t see.

He also got some good pictures of juveniles; we are both beginning to appreciate the wing patterns of the juveniles – lots of variety in their look before they get their adult plumage.

I took a picture of one of the two cranes that are on the top of the dam facing the lake. I assume they are used to get large debris that washes down the Susquehanna from points north out of the water.

Gleanings of the Week Ending December 28, 2019

/

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 Wild Bird Photographs of the Week: Colourful Birds – National Geographic Society Newsroom – Starting off this last gleanings list of 2019 with birds! My favorite picture of this set is the scarlet macaw with a stick. Is it eating it or using it as a beak-pick?

Artistic Photographs of Mushrooms and Myxomycetes by Alison Pollack – Focusing on small things in the forest.

In Search of Australia’s Amazing Rainbow Finch – A bird survey experience…and some pictures.

Patchwork of Corn in the Snow – As of late November a lot of corn was unharvested because it was too wet. Corn needs to dry on the stalks before it is harvested and this 2019 crop may not be harvested in some areas until February or March of 2020.

Watching Wildlife on Skis – Winter wildlife….another benefit to being out and about (with proper gear) during the winter.

Life Rides the Wind in the Desert | The Scientist Magazine® - Finding life in the Atacama Desert.

Decking the halls of history: the origins of Christmas decorations – A little historical note for after the holiday.

Image of the Day: Horns and Wings | The Scientist Magazine® - Technology that can turn off genes is the enabler of this research into how horns and wings develop in dung beetles…and maybe other insects too.

Children’s Book Review: Wake up, Woods – A book about native woodland plants for children.

Real Reindeer Are More Amazing Than You Ever Imagined – Another Christmas themed post…about an iconic animal that isn’t just a cartoon.

5 Free eBooks – December 2019

/

I usually pick 3 books to feature in the monthly ‘free eBooks’ post; this month I am featuring 5. The titles all begin  “An Artist in…” and there were published between 1910 and 1915 although not by the same publisher. I think of them as a window into 5 places just before World War I: Spain, Egypt, Italy, Corfu and the Riviera. I am reminded that artists tend to correct ‘imperfections’ as they paint…even if they are trying for realism! Enjoy the scenes from over 100 years ago!

Camera on the Birdfeeder

/

The new ‘toy’ we are playing with over this holiday week is a camera on our birdfeeder!

So far, we’ve been experimenting with temporary mounting on ladders to decide where to position it more permanently and adjusting parameters. The camera is not very big physically (the white blob on the right side near the top of the ladder is the camera).

This was my first image I clipped from one of the videos – a female red-bellied woodpecker.

I’ll get better with my editing over time. It’s very different than my usual pictures through my office window.

Ever see a squirrel climb a ladder? This one climbed right up to the camera after it was unsuccessful in dumping the seed from the bird feeder!

Next steps are to mount the camera from the eve of our covered deck and put out the small solar panel to help keep it charged. I’ll share some the technical details of our set up…once we get it working a bit better. My husband and I are enjoying the project!
