NOTES: Neotropical Institute Cut # 7. Bulk reel: 255
Weather: Light cloudy. There appeared to be four birds making up the "colony" on this tree:
One male typical cruentatus. This male was seen to copulate with one of the females.
One male intermediate cruentatus x rubrifrons.
Two females typical rubrifrons.
These four birds were collected. [Recordist left space for the numbers of the specimens but did not indicate the numbers in those spaces.]
a) One call by the male typical cruentatus. Quality: 1-2. Level: +5.
Then additional calls, some of which are very likely by the same bird.
