    Equipment Note

NOTES: Neotropical Institute Cut # 11. Bulk reel: 257a) These are long drums (D. lineatus). The bird was not seen. I file them here because playback of them brought a reaction from this species (see b). Also note that one or more of them is a bit broken in the rhythm. Near the beginning a call of the Lineated Woodpecker is heard but it seems to be coming from farther away. Quality: 1-2. Level: 5.b) When I played back a), a male Crimson-crested flew in immediately and alighted on a dead tree in full view only 30 m. away. The reflector is focused on it and it produces long drums of a very broken rhythm. Note that long drums may also be heard in the "middle distance" and the "far distance" background. I believe the "middle distance" drum is also a Crimson-crested for it is occasionally slightly broken in rhythm. The "far distance" drum may be of the Lineated for again we hear the call of this species, although its distance relative to the drums is difficult to assess.Just before the last part a pair of Ara severa are heard as they flew in.In the last part, besides the drum "in focus" another is heard quite close. It is not broken in rhythm. Actually that bird is about equidistant from me as the bird in focus, but to my right. I couldn't see it, though, as it was hidden by an intervening foliaged tree. However, I tried to focus on it, but a bird then flew from this spot and alighted beside the previous male. This bird also proved to be a male. I believe it may be the bird that was previously heard in the "middle distance." Both these birds gave broken drums but I failed to record them as I was changing tape. After I was again ready they did not drum again but sat silently for a few minutes and then flew to a different dead tree, also in plain view.c) This is definitely P. [D.] melanoleucos. PAS. Upon alighting on the new tree, one of the birds started a series of "fuss notes" and the other gave one short drum. These two males remained in this tree until ~ 6:15 AM with the fuss notes continuing all the time. They then flew to other places over a large area and foraged. The one male followed the other and never ceased its fuss notes. A female was soon found to be foraging with them but not in their immediate company. At 1:40 PM this was still going on. Note: In the background are heard some long drums. These may be of the Lineated Woodpecker.Note: Parts a) & b) are much in doubt. The long drums of a) seem surely to be of D. lineatus but then b) seems quite confusing. I suspect I misidentified the birds. See my note A under Cut 8.
