Media notes
Toop calls recorded while the bird was perched only a few meters from me. Edits to the file: trimmed and normalized to -3 dB.
Observation details
The two I saw well were an adult male and a HY bird with prominent brown streaks. I also heard at least three others. Audio spectrograms generated from recordings I obtained indicate that they were flight call type 2s, which are expected in this area. The spectrograms show classic type 2 flight calls that are rapidly downward slurring with a distinct kink near the middle. The flight calls are emphatic and last about 0.05 seconds. Since January, 2011, every red crossbill flight call type that I've recorded in the mountains of Los Angeles, San Bernardino, Riverside, Ventura, and Kern Counties has been type 2.
