The elusive Mangrove Warbler

It looks like a Yellow Warbler, but it has a uniquely colored head.  Well, in fact it is a Yellow Warbler, a subspecies of it.

They like to hide in, you guessed it, mangroves!

They bounce around, picking bugs, so you know they’re in there, but it’s hard to get a bead on one.

You have to watch and wait until it shows itself through a window in the foliage.
