观察细节
two BTBW were engaged in counter singing along territorial lines. While making the recording they did not engage each other in combat but may have previous to the recording. The bird recorded was making their aggressive calls multiple times from inside the boundaries of his territory as mapped over several days of territory mapping and sighting of this individual (although not individual color banded and based on location on virtual grid). I was unable to locate any females within the immediate area at the time of the recording. No playback was used and the subject was overhead by about 3-5 meters.
