Hi all,
This morning at Ft Rosecrans, I recorded what looks to me in the spectrogram like a Type-4 Red Crossbill. I ran into and birded with Adrian Hinkle, who mentioned hearing likely Type 4s/non-Type 2s in a large flock, leading me to check my recordings afterwards. This one was mixed in with a small flock of about half a dozen more expected Type 2s.
The finch irruption this morning at Rosecrans was really amazing in general - I counted on my end ~95 Red Crossbills in numerous flocks generally southbound, along with a Cassin's Finch, two Purple Finches, and two Pine Siskins, with greatest numbers at the south end of the cemetery. Standard Time is finally good for something!
