Field Marks and Identifying Characteristics: |
There were 2 observations in the campground. The 1st was in a mixed
flock with Red Crossbills, as they were flying over I heard the
distinctive 4 syllable flight call of a WWCR, I then spotted the bird
making the calls and it landed in a dead snag, photos show the white
wing bars. It was a dull yellow-orange, so either an adult female or
immature male(not an adult male), but calls were the main ID feature.
Later I heard another small group of 2 or 3 WWCR, we did see them in the
tops of the spruce feeding and calling(the 4 syllable flight calls), but
lighting was such it was hard to see much other than they were
crossbills making WWCR calls. (see photos) |
Song or call & method of delivery: | I mainly heard the 4 syllable flight call, similar to these calls: https://macaulaylibrary.org/asset/103203. (Note, these are just examples of what I heard and not recordings of the birds in this record). |
Behavior: | Landing in tops of spruce and feeding on cones, also flying between tree tops and landing in a dead snag |
Habitat: | Subalpine Spruce-Fir forest, with a mix of Engelmann Spruce and Sub-alpine Fir |
Similar
species and
how were they eliminated: |
Red Crossil: very similar but calls very different, single syllable Kip Kip flight calls and they don't do the 4 syllable flight calls. Males Overall duller brick orangey red with solid black wings. Some can have faint wingbars but that is unusual. Juveniles: also very gray and streaky, and more often show faint wingbars-calls best used to tell them apart. Overall structure is different: Red Crossbills are chunkier with a bigger head and bill and shorter tail. Direct comparison of both calls and visual ID as many Red Crossbill were also present. |
