Media notes
Recorded in slightly windy conditions with an iPhone. Edits to the file: trimmed at both ends and normalized to -3 dB, which amplified the sound. A Cassin's Finch is also audible.
Observation details
Identified as type 2s by a recording of their flight calls. The calls are emphatic, loud, and rapidly downward-sweeping. Most of the flight calls show a very brief rise in the frequency followed by a rapid and much larger drop in the frequency. This is common in type 2s. Some of the calls visible in the audio spectrogram show a "kink" near the top, which is a slightly different variant of type 2 calls. To date, type 2s are the only flight call type found in the transverse and peninsular ranges of southern California. A couple of us got brief views of perched birds. We heard crossbills intermittently spread out along the trail from Dawson Saddle to the junction with the Pacific Crest Trail. Most were heard and seen in flight but one was singing loudly in lodgepole pines near the PCT trail junction. Due to the developing Jeffrey pine, lodgepole pine, and limber pine cone crops, it seems likely that crossbills will attempt to nest and linger in this area for a while. The recording also has calls from a Cassin's finch.
