Behavior and other notes: An adult male Yellow-throated Warbler singing dawn songs from high in a Sycamore. At 2:42 he begins to give a lot of call notes. At this point it is apparent that a male Warbling Vireo is beside the YTWA. The YTWA appears to be excited and upset that the WAVI is there and singing. The YTWA continues with the chip calls and starts to give squeaky calls that I have never heard from this species. A good example that these sneaky calls are from the YTWA occurs at 3:51-3:52 where the WAVI is singing at the same time the YTWA is giving these odd calls. Recorder HPF on at 80 Hz, -12 dB/octave. Distance to source: 12 meters. Recording Time: 0555 (UTC -4). Temperature 11.1°C. Habitat: eastern deciduous forest, riparian. Specific location: C&O Canal towpath at the Antietam aqueduct., Washington Co., Maryland. Latitude 39.4168332, Longitude -77.7453280. Elevation 106 meters. ID’d by: Sight and sound 100%. Equipment notes: Recorder HPF on at 80Hz, -12dB/octave. Recordist original file name: WH_22T0207_Yellow-throated Warbler dawn song and interaction with WAVI_Washington Co MD_ML.wav
