Media notes
Terrible recording, best I could get with wind funneling down canyon narrowing and standing right next to a flowing stream. So a lot of noise. No noise-cancelling filter run to preserve call notes. These call were given in flight, when the group of 4 flew over my head to join the group of 7. Females and first-year males in this group.
Observation details
7+4 perched high in bare twigs of snags, uphill of petroglyphs. Elevation 6,160'. Mostly females and first-year males, at least one streaky juvenile plumage also— Sibley says that plumage Jan-Sept but BoW says juvenile plumage present “primarily June–October in North American populations, although some populations may breed during at least 10 mo of the year, so juveniles may appear in all months except perhaps January and February.“} Recording attached. Only recording I could get, when group of 4 moved to join group of 7, lots of wind and running stream background noise. I think these are Type 6, Sierra Madre, based on high "cheep-cheep" flight call (https://ebird.org/news/crossbills-of-north-america-species-and-red-crossbill-call-types/). Additional data: at this location dominant pine is Apache Pine, which is this type's preferred pine. Also wonder if late juvenile plumage has something to do with type population. I'm sending the audio in as requested to the Cornell crossbill project to confirm type ID (their answer: "The specs sort of look like type 2, but I'm not sure we can get enough from this recording to make a definitive ID.")
