I am almost certain he was Type 4, as I heard the calls. I then caught two Type 4 birds (a ? at a ?) from a flock of about 8 Type 4's.

Pine grosbeaks were heard, and a band of gray jays were around. After catching the first two birds, another flock of Type 4's came in and I got 4 birds -- one turned out to be a Type 5 ? with very large testes -- certainly in breeding condition.
The wild Type 2's I saw were in large flocks of over 10 birds for
