Afternoon songs by a new individual that was recorded in rather scrubby forest with scattered taller trees along the old logging road 3.5 kilometers beyond the bridge over the Río Grande. [8° 06’ 43.0” N, 61° 39‘ 50.0” W, 283 meters]. This bird apparently began singing at about 16:00, after which I initially got onto it at about 16:06. When recorded in the first part of this cut, the unseen bird was about 10-13 meters up and about 20-25 meters away in an 18-meter tall tree with dense tangles. The second part of this recording began just before 16:45:37, after the bird first went quiet, then moved to trees well back from the road, but eventually returned to the tree where it was for the first part of the recording (about 25 meters away). Shortly thereafter it moved again, when it crossed the road, probably 30 meters away and seemingly only a few meters up at first, but as near as 20-25 meters away and <15 meters up in the mid-levels of a relatively large, vine-tangled tree on the north side of the road after I walked up on it for the third part of the recording, which began just before 16:52:16. The bird was still moving quite a bit during the third part of the recording, when it was as close as 15 meters away and at times only 5-8 meters up in very dense tangles. It moved some distance back from the road on the north side at the conclusion of the third part of the recording, after which I got back onto it at 16:58:58, after missing two songs, with the bird now about 20-40 meters away and still quite low (possibly 3-5 meters up), but still moving about quite a bit. I missed songs at 17:15:48 and 17:16:03, after which I turned the recorder back on at 17:16:15, but the bird was singing only infrequently and it had moved further back, so the fifth part of this recording has only one distant song, after which I missed two more songs at 17:17:05 and 17:18:22. Back on again for the sixth part of the recording at 17:19:18, after missing two more songs, with the bird now 25 meters away in vine tangles but somewhat higher than it had been, but still singing infrequently, so this part contains only two songs. I got back onto the bird for the seventh part of the recording at 17:24:39 after missing about eight songs when the bird moved back again, with the bird 30-40 meters away and in the mid-levels of a large tree with dense vine tangles (though initially thought to be higher up and farther away). The bird moved yet again at the end of the seventh part of the recording. I got back onto the bird at 17:43:23 after missing three more songs when the bird flew back across the road to a tall tree back in on south side of the road, where it was high up in 25-meter tall trees and apparently about 50 meters away. After moving further away from the road (75-100 meters back and in a place I was unable to reach), the bird again sang at 17:45:50. this bird continued to sing consistently, but with long intervals between songs, about 100 meters south of the road in an area that I was unable to reach. It then gave a long-call at 18:09:30, from this same area before moving and then giving a single song at 18:11:14 and then a long-call at 18:12:15, both from a tree near the road just before the curve. The vegetation was here very dense second-growth of vines, palms, and Heliconia that I was not able to traverse, so I was able to record the bird only when it was in trees that were relatively close to the road. Partly cloudy (with clouds clearing to mostly clear skies by the end of the recording), consistent mild (5+ knot) breeze, 84-85° F. ML: Subject identified by recordist as Xiphorhynchus guttatus polystictus but assigned to Xiphorhynchus guttatus [guttatus Group] to conform to eBird Taxonomy (v. 2016). -[Brad Walker 16Aug2016]. This individual was recorded multiple times and can be found in the following ML records: 222389, 22239
