观察细节
I suppose, unexpected in this habitat/flagged as rare. Well observed empidonax - singing near continuously from various perches. Short primary projection giving a long-tailed silhouette, relatively long bill/with mostly pale lower mandible and dark tip. was never observed at closer than 30 or so meters so the main diagnostic, for the ID was its repeated vocalizations, quite different from those of a dusky flycatcher which can be visually similar. Recording of vocalizations to be added.
