Type 5 flight calls. The calls are slightly wider in duration than usual, probably because the sounds echoed off something nearby. Edits: trimmed. Not normalized due to the loud volume of handling noise about 2 seconds in. Uploaded 2017 Sep 27.
Gözlem detayları
Vocalizations recorded. Sonograms show the characteristic pattern of type 5s: two more-or-less parallel, downward-slurring, simultaneous, and brief (~0.05 seconds) sounds centered at a frequency of about 4 kHz. Also seen on treetops and in flight. A recording of one of the birds is available on the Xeno-Canto website at: http://www.xeno-canto.org/148516 Direct link to the Xeno-Canto Audio File I have previous experience with Type 5 red crossbills: I recorded some near Lake Tahoe, Nevada in Oct. 2012, and in the San Francisco Mountains near Flagstaff, Arizona in April, 2013 (examples are available on Xeno-Canto). I have extensive experience with red crossbill types 2 and 3 and some (but limited) experience with types 4 (Tacoma, WA) and 10 (Kennebec County, Maine). Most of my experience with recording red crossbills has been in southern California.
