Sunny and cool at midmorning, with the smell of woodsmoke drifing up from the valley. The bluejay who stumps the bird app is making his one-of-a-kind call — almost a croon. At random moments, black walnuts drop onto the driveway with a thud.
Overcast and cool. When I tire of feeding myself to the mosquitoes, I don a bug hat and go into the yard with my phone to identify whatever has been skeletonizing trees and shrubs: angle-lined prominent moth caterpillars on the bigtooth aspen, pinstriped in green but too hairy to be extra twigs, and dogwood sawfly larvae on the silky dogwoods, curled into fat white moons.
