field notes 247. 1. Groth 1990 Dec. 12 Animal Behavior Station University of California Berkeley. Began to dismantle the colony of captive crossbills today. First removed the four birds (♂385 + ♀?) from the middle two cells. gave numbers 766 + 767 to the two captive-raised ♂♀ [daughters of "59" and "33"], one of which nested last spring and raised the new ♀, now numbered 768. Recorded first bird 767, who sounds type 2-like. 768 also called in type 2 calls. At 11:05 am some wild type 2 crossbills flew over the behavior station, but did not elicit much vocalization from the captives. I then prepped bird 767 ... more wild type 2s flew over at around 11:55 - 12:30 in about three incidences. Then I caught and removed "33" and "59" from their cell. 385 gave some twittering calls, and ♀766 responded with the same calls. I recorded flight calls from "33", then removed one ♀ juvenile from "33's" cell. I then got true flight calls from 385 as wild type 2s flew in the treetops at the behavior station. As I started leaving, I put "33","59", and their daughter back in their cell (the juv.♀ did not call, nor did "59"). I took 385 & his daughter & 766 home to prepare. Dec 13 I arrived at the A.B.S. at around 1:30 pm. I removed five crossbills from the cell of "33" & "59", including two young ♂♀ (now numbered 769 & 770 [bill L]). Assuming "59" is the male with the right-crossing bill, the other two males are both left-crossing & are assumed to be the young males. The birds were quite non-vocal, except for alarm call series by "59", also some vocalized calls, including flight calls, of young ♀ 770. Young male 771 also was recorded in "buce"
