Top 25 birds of the week: Green Colours! – So many beautiful birds…

150-Year-Old Boxwoods Lost To Blight At Carl Sandburg Home – My daughter and I visited the Carl Sandburg Historical Site in 2003 when we were on our way from Maryland to meet family members coming from Texas for a Georgia vacation. It was the first time I had driven a car with a nav system! We enjoyed walking the grounds and touring the house more than we expected. It’s sad that the boxwood there will be cut down.

What early-budding trees tell us about genetics, climate change -- ScienceDaily – Our plum and cherry trees are the ‘fruitless’ kind but they were in full bloom when our temperatures dipped into the mid-20s. I wonder how many orchards are going to have less fruit this year.

Hope and Peril for North America’s “Snow Parrot” – A parrot that lives in pine forests. Their range once extended into the US from northern Mexico, but they’ve been gone since the 1930s.It’s only in the past few years that their migration and winter grounds in the Mexican state of Durango have been discovered. There are efforts to safeguard the free-living birds and continue captive breeding programs in zoos (like the San Diego Zoo) with the plan to begin reintroducing birds into the wild in the future.

The Kodak Brownie: The Camera That Made Photography Accessible – My mother was taking pictures of her siblings in the 1940s….with a Brownie. There is one of her twin sisters (maybe 4 or 5 years old) peeking over the windowsill of the bathroom window (they were standing in the bathtub!); I always wondered if she had help on the inside positioning them while she got outside to get the picture. It must have been a warm day since the window was open!

Dangerous landfill pollutants ranked in order of toxicity -- ScienceDaily – The technique can help landfill managers mitigate risk for a particular site rather than taking generic actions that might not address the biggest problems.

For the First Time in 75 Years, a New Invasive Species of Mosquito Was Found in Florida | Smart News | Smithsonian Magazine  - The mosquito that can carry yellow fever and other diseases was found in Florida last year. That does not bode well for keeping tropical diseases at bay in the US as the climate continues to warm.

Scythian people weren't just nomadic warriors, but sometimes settled down: Varied diets and limited mobility challenge stereotypes of ancient steppe populations -- ScienceDaily – Not all Scythians were nomadic. The majority of them might have remained local…farming millet and raising livestock!

Texas might be the next place this technique will be used – pending state and local approval.

Earthquakes and insects on Alaska road trips - The Field - AGU Blogosphere – I browsed this article and remembered learning about the 1964 earthquake from the Weekly Reader in elementary school. So -this was an update about what the place is like today…with the town moved completely.

Nuvve And Blue Bird Combine To Create Electric School Buses That Are V2G Enabled – I wish all new school buses would be electric…and charged via renewable means…for the planet and, more directly, for healthier air for young lungs.

Top 25 birds of the week: Colours - Wild Bird Revolution – Beautiful birds….I never get tired of looking at images of the diversity in color and form the birds display.

The U.S. drought vulnerability rankings are in: How does your state compare? | NOAA Climate.gov – Looking at states that I know well because I have family members living there Maryland, Texas and Missouri have a high ability to adapt whereas Oklahoma has a very low ability to adapt (because they have an outdated drought plan and limited irrigation combined with extensive agriculture and cattle ranching). Is Oklahoma headed toward another dust bowl?

Five myths about wildfires - BBC Future – The 5 myths debunked in this article are: regularly logging forests prevents forest fires; there is nothing you can do to protect your property; wildfires are an inevitable fact of nature; all wildfires are bad and must be quenched immediately; it is possible to eradicate (control) all wildfires

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.

Why cavemen needed no braces – Our diet and behavior have changed a lot since the stone and hunter/gather stages of our species….and those changes have impacted our jaw (and teeth and air way). There are more health consequences than just crooked teeth. I’ve bought the book (Kindle version) to learn more.

Characteristics that give viruses pandemic potential – An article from The Scientist that is more future oriented. What we are experiencing with COVID-19 is something that could happen again. The article talks about various types of viruses that pose the greatest threats.

Peer into the Past with Photorealistic Portraits of Roman Emperors – Taking historical sculptures and drawings to the next level. The Smithsonian Magazine summary has images of Augustus, Maximus Thrax, Caligula, and Nero….the rest can be viewed in Daniel Voshart’s site.

Amazing Macro Winners of the International Garden Photographer of the Year 2020 – Visual treats. This it the type post that gives me ideas about things to try with my own camera.

Wolverines Seen Roaming About Mount Rainier National Park – What a boon remotely triggered cameras can be….and then DNA testing of hair to determine relationships!

 Meet the Squad of Mosquito-Eating Species – Birds, dragonflies, newts, aquatic turtles, and bats. We haven’t noticed very many mosquitoes around this year, but we try to replace the water in our bird baths frequently and make sure our gutters are draining properly. Having the birds around our house probably helps…and the turtles at the neighborhood pond do their part.

Unique Activities for Yesterday:

Going to the basement during a storm. Our phones went off with tornado warnings – which is rare in Maryland. We went to the basement. It turned out to be only heavy rain for us (not very windy either); to the east and south of where we live there was a lot of damage with trees/big branches falling and shingles flying.

Cleaning the leaves off the deck. Over the past week we’ve had several fronts come through that have blown leaves and branches onto our deck. They were still wet when I went out to clean up. I dumped the sediment that had accumulated in the bird bath too.

Finding Witches’ Butter. I photographed the fruiting bodies of Witches’ Butter on our deck railing. The deck is over 25 years old and even regular treatment can’t keep it clear for fungus; it is only visible during times when the wood is wet for several days.

I’m more concerned about a window frame that has the same fungus growing. I’m not keen about replacing the window but we might have to consider it.

Bad molars? The origins of wisdom teeth – I’ve always wondered why so many people must have their wisdom teeth out. All 4 of mine were pulled when I was 19 because they were impacted. It turns out that eating a crunch/chewy diet when we are young may help the jaw grow long enough to accommodate these late molars. Wish I would have known that; I might have fed my daughter a bit differently. Too late now.

Climate Smart Farming CSF Climate Change in Your County and Climate Smart Farming – Cornell Institute for Climate Smart Solutions – The first link is a county by county look at the history of temperature and precipitation in the Northeast. The second it about the research being done to help farmers plan for extreme weather events…that have become more common in recent years.

Illnesses from Mosquitoes and Ticks on the Rise | Berkeley Wellness – In our area Lyme disease (from ticks) is the one we worry about the most but there might be others that are going to become more problematic. Maryland has more mosquitos that usual right now…unpleasant and maybe unhealthy.

Red Meat Allergies Caused by Tick Bites are on the Rise – Aargh! I hadn’t heard of this one before.

Feeding the gods: Hundreds of skulls reveal massive scale of human sacrifice in Aztec capital | Science | AAAS – A short video and article about structures recently excavated that include skulls of human sacrifice victims as described by Spanish conquistadors.

China’s Plastic Ban Will Flood Us with Trash | Smart News | Smithsonian – Now that China isn’t accepting the plastic we throw in recycling – where is it going? Are our landfills going to be even more massive? Ideally recycling would get better (and done closer to where the material entered the system) rather than worse.

Petrified Forest National Park Becomes World’s Newest International Dark Sky Park – I’ve visited this park several times…and now it’s a dark sky site. It’s a long way from Maryland but maybe we’ll eventually get there for a star party!

Why Europe’s astronauts are learning Chinese – China is taking the steps to be the third big player in space….and Europe is planning to cooperate with them just as it does with the US and Russia.
