NOTES: Neotropical Institute Cut # 1. Bulk reel: 454 Weather: clear NOTES: "a) Some calls given naturally by foraging birds; a pair was present - this section is 1:21. Then various vocalizations after playback of the above calls, which excited the birds very much, and later by periodic playback. This section is 3.33. b) Recorded at 0700 hours on the same day and location. This recording was obtained incidentally. At the beginning and about 0:30 are heard phrases that I think may be of the present species but it is not sure. This section is 0:55. Recorded on 20Feb73 at km23.3 (old). Added another phrase recorded incidentally that might possibly be of this species, but not at all sure; however it is like the two phrases in the preceding part. Recorded using SN [Nagra SN?-LNS] without a parabola at 7.5 ips." PAS.
