媒体文件注释

A larger group, maybe about a dozen, moved from the larches to trees closer to the creek. This recording was as they flew off over the road. Matt Young: It’s an odd cut because the type 4 is buried I think and the type 1 is trying to call match the type 4 and one of the type 1 or 2 is trying to match a type 1 or 2. It’s hard to be sure.

观察细节

I consulted with Matt Young (Finch Research Network) who helped identify the call types in my recordings. (Will upload audio)
