觀察細節
While walking below Zaytuna College, I heard jip-jipping emanated from near Woods Reservoir. The small flock took flight from the tops of redwoods, flying farther from me, while continuing to vocalize. Visible for only for a few seconds at most; appeared to land and went silent, but may have flown into Wildcat Canyon. Attempted recording but crossbills were 100+ yds away. A few sets of jip-jip or jip are barely audible above the ambient sounds. The calls sound rounder than the Type 3 that I heard a few days ago, and these may be Type 2. Incredibly, the calls can be visualized in Raven Lite, and the strongest frequency is at about 3kHz, which is consistent with that from Type 2. Original recording was trimmed and the gain increased significantly. This edited recording is posted here.
