This bird was initially unseen but about 20-25 meters away and low in forest understory on a relatively gentle slope about three-quarters of the way from the peak down to the house at the upper edge of the coffee plantation [10° 05’ 58.3” N, 63° 48’ 43.3” W, 1480 meters – along road about 50 meters below where I made this recording]. I saw the bird quite well just before I began recording the second part, but it moved off (apparently a short way down the same log) to a place just out of view before I began recording, when it was presumably 10 meters away and 1/2-1 meters up on a horizontal log amid a dense understory thicket. The closer bird stopped singing right after I recorded the first part of this cut, and it was only after quite a bit of playback over a period of about 20 minutes that it came in silently and eventually perched motionless and began singing again. Apart from pointing the head upward and opening the bill, it did not display when it sang. Note also that these songs are quite different than those on the Isler Antbird CD (these being quite a bit lower in frequency), suggesting that geographic variation in song may be marked in this species. Weather conditions same [clear, with an intermittent trace breeze, 71-72º F]. ML: 150 Hz high-pass scientific filter applied in Adobe Audition CC 2015 to all segments. Equipment Notes: Sennheiser powered using phantom power and with filter in flat position and attenuator off for all recordings. Nagra input set at 2 mV / Pa and low-pass filter in flat position unless noted otherwise.
