J. Groth 1986 journal 127. Type 4 bird (on tape). I took a shot at the type 4 ♀, but only "stunned" her, as she fell swinging upside down in the tree, and as I reached for her she flew strongly to nearby trees, I thought I heard her mixing w/ the type 2's but no visual sign of her. Later, I caught a juvenile from a flock of type 2's -- bird #52 (J66349). I also set up a net on a ridge above the camp, -- more exposed, I heard birds through the evening, but attracted none. I estimate a total sightings as about 70 individual Type 2's and 30 Type 4's -- most were not identified to age or sex. July 30 Today I collected a total of ten crossbills: 6 Type 2's and 4 Type 4's. I stopped netting between about noon and 3 pm, to avoid heat and I had already captured many, I began to release some birds arbitrarily. Other flocks of crossbills were seen today. Nothing but about a 65/35 ratio of Type 2's to Type 4's -- and birds around
