Description

I watched Acorn Woodpeckers bring food to this nest cavity in a black oak multiple times. The young were squealing, which seems to be typical for this species (they don't sound much like the various other woodpecker young that I've heard). There was a moment of panic when a Cooper's Hawk flew into the area and chased after one of the adults, then perched near the granary tree (too bad I didn't have my spotting scope set up yet - damn!). But after a minute or so, it left and the woodpeckers carried on with the task of feeding the nestlings. I was interested to see them nesting in the same cavity as last year. I've included a picture of the nest tree. The nest cavity is near the top of the tree and is circled in white.

Great pictures! They show so many aspects of the bird and its habits and environment.

Thanks CuriousGeorge! I'm participating in the update of the Sonoma County Breeding Bird Atlas, so I spend a lot of time looking for nesting and evidence of breeding. It's been an amazing opportunity to learn all sorts of neat things about the local avifauna.
