These guys have probably been around a while but I’ve considered them to be pretty generic – maybe not so much!
The Cornell Merlin app IDs all of these photos as a Yellow-Rumped Warbler.
There’s definitely some yellow on those rumps.
Now that I know what to look for, it’s really obvious when they’re flying – that yellow patch is really prominent.
This guy, however, wants to give me the stink-eye for talking about his butt. Sorry, dude!
