NOTES: Neotropical Institute Cut # 1. specimen collected; Bulk reel: 35; Extra cut length: 8:01 Ba) Natural song. Bird in distance. Quality: 2. Level: +5. 7.5 ips.(In background is Turdus albicollis, Micrastur mirandollei, and Bucco capensis.)b) Then after playback. Grallaria varia sings conspicuously at one place.) Bird came close but was high in tree. This bird was seen fairly well after it came in due to playback. It appeared to be this species but in dim light of dawn I couldn't be 100% sure. I shot it and it fell but recovered half-way down and flew away. Quality: 1-2. Level: +5. 3.75 ips.[Apparently later note by recordist:] Note - the identification is correct.c) This is the song that rpeceded part a). I had the other recorder running with open mike and thus obatined this. Note that the song starts with a single note call. (Can hear rather loudly my playback of field tape of M. mirandollei.) Then hear when gilvicollis changes to two-note song. This recording is cut at point where can hear the voice announcement I made while recording the gilvicollis with other recorder (part a), to provide a definite tie-in. 3.75 ips.d) This is the song that preceded b), obtained same way. The bird started singing ~ 4.5 minutes from start of first playback. This recording is continued to the moment of the shot, thus including some song that was not at end of b). (Grallaria varia sings rather prominently at beginning.)At ~ 3' of this part can hear the other bird (= Bucco capensis) that was also singing part a).
