Bird #1. Apparently not a definit. plumaged male, although light was not favorable for accurate color appraisal. Bird appeared to be olive-gray. I noticed no white chins nor white wing speculum, the latter surprising for the bill appeared to be corn yellow. Natural song. This is continuous song. As I discovered subsequently, with this pop. such tontinuous song is given only at dawn, or to a lesser extent late in PM. Quality: 1-2. Level: 0.
Then after playback. Continuous song and toward latter part, more "typical" short phrases. Quality: 2. Level: 0. 138 brown tape. Std.
(Further playback did not attract the bird again. However, I heard short phrases at some distance but couldn't locate them.)
