Luckily, singing season for the veery lasts a long time. They’re still at it, mostly in the mornings and evenings.
Hummingbirds can distinguish many more colors than humans. 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.
Hobblebush leaves are nice in the summer, colorful in autumn, but now, as they unfurl, they might be at their best: an intricate tapestry, white against tan. An elegant tan that we’re probably supposed to call ecru.
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.
Now that the wasps have filled all the ground holes in all the electrical outlets in the garage, they’ve begun using the fancy solitary bee and wasp apartment house that was made of reeds especially for them. The female lays an egg, tucks in provisions for the larva, and fills the hole with fine mud, without my noticing. I’ll try to catch her in action from now on.
The per day change in day length is at a low around the solstices: it’s changed less than a minute per day since December 9th. Starting today, the increase in day length is more than a minute per day and it’s going to increase to about three minutes a day until we approach the summer solstice.
Virginia creeper and grapes are foodplants for Abbott’s sphinx moth caterpillars. Large green spots – much like the immature grapes nearby – cover the back of this striking insect. They will pupate soon, so check for them now.
