    Equipment Note

NOTES: Neotropical Institute Cut #29. Bulk reel #530
EBRG captive birds
a) 1400pm. Fair. Song (apparently by two birds) by birds hidden up in a palm. Note that this is not well patterned, especially by one, the birds. Duet could be noticed also in cut 28; se note on back of that editing sheet. At the end of this recording one bird chased another from this tree. The action was too fast and unexpected to observe well but one bird appeared to be black and white and the other brown. I played back the entire recording of part a) with an adult male sitting on a fence wire in full view aprx. 15 meter from me: he paid absolutely no attention to it. (of. also note on back of editing heet for cut 3).
b) 1420pm. Cloudy, fair. Calls at 3.75 ips, then song by an adult male aprx. 6 meter up in a tree. Tis bird then flew down to join others that were foraging aprx 25 meters away. Note that this song (by an adult male) is patterned normally, although largely lacking the ÒtypicalÓ motifs, which may be common in off-season singing (eg my captive R. yellow). This song was played back quite loudly but none of the birds paid any attention to it.
