Identified to type by calls. A few Type 4's and a Type 10 were also recorded in the area but I believe all, or at least the vast majority, of those pictured were Type 2's.
觀察細節
Many audio and video recordings obtained at close range as the birds fed on jack-red pine and gritted on sandy road. Most recordings were Type 2's and included toops, chitters, alarm calls, singing, and flight calls. One clip from this site had Type 4 and a western Type 10. All typed by Tim Spahr.
