ID confirmed by Matt Young, Cornell.
观察细节
I detected roughly a hundred crossbills in the area I worked. I submitted 14 recordings to Matt Young (Cornell), and Type 2 were detected on 9 of them (Type 4 were detected on 11). As a result, I'm estimating that roughly half of the birds I detected were Type 2s. Some individuals and flocks were type-specific, others were mixed. The habitat included white, red, and jack pines, but mixed flocks seen foraging on cones of red pines, and one flock of type 4 foraged on jack pine.
