觀察細節
Better study of 13 dark-breasted Cacklers seen yesterday morning. Their breasts are dark brown but paler shade of brown than the presumed minima that was also present again this morning. None appear to have gular stripe. Wing tips extend past tip of tail. There is some variability in size among the group but on average they appear 2 to 3 times larger than the minima and roughly half the size of the pale breasted moffitti. The bill appears stubbier and the head subtly rounder than the moffitti. The group took off with others but I can’t say if they called or not, but I didn’t hear any calls other than CAGO calls. My gut says Cackling, but I’m not completely sure. Photos.
