Yellow Warbler

There are actually 2 species of the Yellow Warbler here, the migrants from the north and a resident one here called Mangrove Swallow. But they look identical except for the resident adult male who has a reddish or rust-colored head or cap. The females and juveniles look identical. Thus, I have all my photos in one gallery, Northern/Mangrove Yellow Warbler, covering both Setophaga aestiva and Setophaga petechia. And I’m pretty sure that this one is a migrant male or Northern Yellow Warbler, Setophaga aestiva, male. I have more photos of him in the gallery. And who knows? He just may have migrated here from Nashville like I did! 🙂
