Feeding on tiny acorns, probably Pin Oak acorns.

觀察細節

Four crows at the pond area feeding on acorns from either a Pin Oak or maybe a Scarlet Oak. Leaves look 'Pin' but cap on small acorns is deep, more like 'Scarlet'. The crows constantly flying into the oak tree for acorns (photo), then flying out as the next crow flies in, while Jays wait, complaining periodically.
