On the oak trees, the acorns had not yet reached their final egg in a fancy eggcup shape, but were filling out towards that goal last month.

A robin anting: spread its its feathers as widely as possible as possible, then pressing down hard on the ground so that ants can get at it. Thought to be a method of getting rid of small parasites or of grooming the feathers.
This robin chose to do it, at least twice, on ground with few if any ants.
