Not just ultraviolet, but ultraviolet+green, ultraviolet+red, and ultraviolet+yellow. Researchers spent three summers deploying sugar of various hues to discover this. We are “color-blind compared to birds” according to one of the scientists. And, according to me, it’s good to clean out the hummingbird feeder before it gets moldy.

Most of us have heard that the CO2 level in Earth’s atmosphere today is higher than it’s been in a million years, but a new study, published in Geology, concludes that there’s now more CO2 than there has been in the past 23 million years. Something to think about while we fan ourselves.
Jefferson salamanders are the earliest vernal pool visitors, arriving even when there’s lots of ice.
The dry weather continues in most places. The US Drought Monitor has most of Vermont listed as “abnormally dry,” with the eastern part of the state listed as “moderate drought.”
Hummingbirds have been reported in the past few days not far from where I live. They typically arrive here around May 15th. It’s been a bit colder than normal here in the past month, making a person wonder what’s up.
Yesterday’s thunderstorm brought an inch of rain to the village about 2 miles from here and just a fleeting dampness here. An unwelcome but not unfamiliar occurrence.
The hot, hot weather in late May took a toll on apple blossoms. They seem to have opened up on one day and disappeared the next. Of course, my sense of time, and most everyone else’s, may be a bit off, due to isolation and discombobulation.
Both black ash and white ash leaf out much later than most other trees and are now easy to spot. The flattened, tan-colored bark on many ash trees sometimes makes them look like they have a bad case of mange. But this condition is caused by a fungus that just feeds on dead bark and does no harm. Not to be confused with damage from the emerald ash borer.
