From the daily, Upper Valley, email blog “Daybreak” comes this link to a fascinating short blurb with photos by Matt Ayers, a bio professor at Dartmouth, entitled “What are all those half-eaten beech leaves on Mt. Cardigan about?” According to Dr. Ayers, “ Caterpillars are more abundant this year than they have been in at least 20 years in our region.”  The big uptick in Yellow-billed Cuckoo sightings in our area is surely due in large part to this explosion in caterpillar numbers. Dr. Ayer’s includes a photo of a male Black-throated Blue Warbler carrying a caterpillar to it’s nest up in the Hubbard Experimental Forest. Not just the cuckoos benefit.
     Also linked in today’s “Daybreak” is a stunning and extraordinary series photographs of hummingbirds in flight  by Christian Spencer showing rainbows created by the diffraction of sunlight through the feathers of the wings. The article dated July 11, 2019 by Sara Barnes is from the Website My Modern Met.
