Overcast but bright. Neither warm nor cool. A Cooper’s hawk dives at a squirrel on a walnut tree at the woods’ edge, misses, then takes fright when the squirrel turns and charges at it, and lands on a nearby limb to take stock and ruffle its feathers before taking off.

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.
