觀察細節
*Low density/scarce spring migrant through NYC. Interacting with a LEFL, both calling, with Alder giving diagnostic “pip” calls aggressively and repeatedly. Adult Traill’s type Empidonax flycatcher with relatively heavy, bicolored bill, olive tones to the upperparts, discernible eye ring, not overly smudgy on breast. Both stopped calling a few seconds before I began audio recording, and I did not hear either vocalize again. Photos.
