    Equipment Note

NOTES: Neotropical Institute Cut # 44. Bulk reel: 380
Rerecorded N-IV to N-4.2 from orig. @ 7.5 on 139.
Location: Same as Cut 21 [see above] but slightly nearer building. Much rain during past days. No activity up to 5:52 AM when some quiet "ao" calls began above path; then other heard below path. Bird above path has a higher voice (= this recording); this bird also gave two wing-whir displays (not recorded). These were typical in rhythm but had a "muffled" sound rather than the usual dry sound. Quality: 3. Level: 0.
Later at this spot up to four birds present, feeding on palm fruit but one of the two birds first present picked at and tried to chase away the new arrivals (which were molting; could see voids in wings) and appeared small. Then recorded a flight (not display).
On way back to building 23/VI/72 I encountered a pair of adults with at least one young, slightly smaller than the one collected the other day.
24/VI. Foggy and windy. No sound birds until 5:45 AM, when what was probably the "high-voiced" bird of yesterday, above path, started quiet calling ("ao"). A type rather between "whines" and "ao" but more birds the former, was later given by this bird after a display flight (then calls here recorded). After a long period of silence the bird then flew (no further display) over in the direction of the palm with fruit. Note: Apparently as result of all recent rain there is now heard practically no bird song of any kind, in contrast with situation a few weeks ago.
25/VI. Clear. @ 5:35 AM. First sounds were "ao" calls, apparently by high-voiced bird, but far away from where has been other days.
