Crossbill correction: Matt Young (a crossbill vocalization guru at Cornell) reviewed my sound files and corrected the type 4 to type 2 and the type 10 to type 4. So all three Red Crossbill types (2,4,5) are expected in Colorado. The Red Crossbill vocalization learning curve is a steep one, but fun!

[snip]...On Sunday, Nov 5, we returned to the area looking for crossbills. In the cemetery (just east of the lake, on the east side of US 287), we found a flock of 21 Red Crossbills. I recorded three different call types, including Type 4 (Douglas Fir), Type 5 (Lodgepole Pine), and Type 10 (Sitka Spruce). I am not aware of previous reports of Type 10 in Colorado....[snip]
Audio for the three red crossbill types has been uploaded to the Macauley Library via eBird, and also uploaded to xeno-canto.org.
