journal 7. J. broth 1984 Behavior Station Nov 17 (cont'd) another flock flew in, composed of about 7 birds -- mostly bright red males. Again, Type 3 calls by the entire flock -- now from this flock were captured. The last crossbills seen today were some Type 4 (the V-shaped calls)... 3 birds, I think 1 ♂ and 2♀ came around, and I recorded the ♂ on tape 45 but none of the 3 were captured or shot. They looked small. Also, today a sharp-shinned hawk attacked caged birds -- but none gave alarm calls. Also seen was a varied thrush. Birds 280, 281, 283, and 284 were killed after tape recording today. Nov 18 Up at ABS again today, with "57" and 282 and 285. 57 gave some good calls, toops, alarms, and song -- all her usual Type 1 (except the flight calls). 282 and 285 were tape recorded and killed. No wild crossbills were heard or seen today. Pine siskins were abundant again. Saw a flock of waxwings with robins.
