. broth 1984 journal 8. Behavior Station Nov 25 Went up to the Animal Behavior Station today. Brought birds "57" and 273 as decoys ... had them in the cage together. At about 10:12 am I heard some "Type 4" calls -- apparently two crossbills -- associated with Pine Siskins. Both birds were captured -- numbers 286 and 287, later tape recorded and killed at about 12:22am. Two other crossbills were seen today, including a lone ♀ (288) who was captured, and a lone ♀ (289) who was captured. The lone ♂ was identified by ear as Type 2, the lone ♀ as type 3. I'm fairly definite - almost certain. These were killed immediately to get crop & stomach contents since it has been apparent on these and all birds taken last weekend that they may be eating fruit since they have had purple stuff on their bills. These were 366, 168 and 169. The Pine Siskins today that I've seen also had purple on the bill. Started fieldwork at about 9:45 ended at about 12:30. Fed captives as usual. Partly cloudy today.
