    Equipment Note

NOTES: Initially natural song by an unseen pair of birds that were 20-22 meters away and 5-6 meters up in the mid-levels of scrubby forest over what appeared to be a seasonally flooded draw along the road through the forest fragment; the last song was recorded after playback, in response to which the male approached silently and was well seen (described on tape), and it eventually began singing intermittently, as it was when I recorded the last song when it was 8-10 meters up overhead; I clearly saw the male as a Thamnophilus punctatus-type bird, but I cannot separate T. ambiguus from T. pelzelni and this site seems to be at an intermediate location; I never saw the female, but there were clearly two birds singing; clouding up again, humid, calm, 84-85¡ F.
