媒体文件注释

Behavior and other notes: Adult male Blackburnian Warbler singing while actively foraging in tops of various deciduous trees. The first song in the cut sounds like a dawn song display with lots of chip calls between songs. There are two quiet vocalizations one at 2:48 and one at 5:16. These are very different from anything I have heard from this species. There was a female conspecific with this male in the same tree. However, they did not appear to be interacting. Recording Time: 0609 (UTC -4). Temperature 15C. Habitat: mixed deciduous woods. Distance to sound source: 12-14 meters. Specific location: Sleepy Creek WMA, high hairpin, Berkeley Co., WV. Latitude 39.511825, Longitude -78.138204. Elevation 488 meters. ID’d by sight and sound; ID confidence 100%. Equipment notes: Recorder HPF on at 80Hz, -12dB/octave.
