Sunny and cool. I happen to spot a moment of tenderness between hummingbirds: he buzzing back and forth a few inches from her perch in the eastern red cedar, she tilting her head back for a lightning-fast meeting of tongues.

Clear and cold at sunrise. The dawn chorus is down to field sparrow, common yellowthroat and goldfinches. Distant crows. A truck jake-breaking through the gap. A red-eyed vireo starts up.

Cool and clearing after yesterday’s storms. A red-bellied woodpecker calls from a dead limb at the top of the tallest black locust, making it sway. Below him on another dead branch, a fledgling is being fed by its mother.

Unseasonably cool with the pall of wildfire smoke over the region. It is as thick as a thin mist and burns my throat. But even though their sun is a lurid red, the goldfinches and a common yellowthroat keep singing.

Heat mediated by a breeze. A hummingbird clearwing moth visits the garden, sipping nectar from bergamot tubes with a straw-like tongue swifter than thought. I read up on the species: its migratory habits, its lack of any hearing, its taste for purple.
