NOTES: Neotropical Institute Cut # 6. Bulk reel: 462. a)19/3/70. 7:20 AM. Natural vocalizations. Quality: 2. Level: +3. Formicarius analis in background. Also Micrastur semitorquatus in the "short song." Quality: 1. Level: +3. Low noise. 203 tape. Much of the calling may be mobbing of the Micrastur by the jays.
In the last part, Thryothorus leucotis is also heard and some of the jays' calls resemble the wren's phrases.
b) 20/3/1970. 1355. More natural vocalizations. Quality: 2. Level: +3. Then probably are not mobbing type calls. Quality: 1. Level: +3.
