The rising sun appears through new holes in the forest understory just after it tops the ridge. Crows and jays are in an uproar over a young peregrine falcon, who hangs around for a couple of hours, periodically giving chase to its most obnoxious persecutors until they all find better things to do elsewhere.

Overcast and cool. A pileated woodpecker flies into the dead top of the tallest black locust in the yard, seemingly oblivious to a swirling conflict between a small flock of local jays and two migrant sharp-shinned hawks. A slow inspection of the treetop turns up nothing worth tapping for, and she flies off, leaving the tree to the jays.

Heavily overcast: a rain sky with no rain. Up in the woods, a Cooper’s hawk begins to chirp, answered seconds later by a red-tailed hawk. The two hawks exchange calls for several minutes before falling silent and letting the jays take over.
