观察细节
First campus record. Female on the north side of Badger Hill. I first heard the persistent "peek" call coming from an unseen bird, and thought it was likely a woodpecker or thrasher. It didn't sound quite familiar (i.e., any of the species I expected to see here) so I stuck with it. After 10 minutes or so it flew and landed in the open, revealing itself to be a Nuttall's/Ladder-backed type woodpecker. I tried playback of both species and it responded with the descending whinny of a Ladder-backed. I was also able to note the barring extending all the way to the top of the back, and buffy coloration on the under parts, all suggesting Ladder-backed. Also buffy (rather than white) nasal tufts and extensive barring on outer tail feathers.
