Male 3 (just south of the boat ramp in the swamp)
观察细节
One singing (M1) along the river closer to the entrance (seen yesterday, heard only today), one on territory at the boat ramp where the river curves east (M2), one on territory just south of the boat ramp in the swamp (M3), and the fourth (M4) farther south along the river (where the side trail south of the boat ramp meets back up with the river; I didn’t check here yesterday). At one point there was a bird calling (chip) where M4 was singing. M4 stopped singing and chipped back-and-forth with this bird. This bird may have been a female (appeared to have less extensive yellow on the underparts) and eventually flew south onto the territory M4 seems to have established.
