This was a lifer for me; seeing the Blackpoll Warbler (Setophaga striata) hopping from branch to branch in Kabalebo. First thing that caught my attention was its size and color. He didn't quite fit well with the residents but at the same time felt he belonged here.
Even though he is called the Blackpoll Warbler he doesn't look like one in these pictures. This one was a non breeding version of the Blackpoll Warbler. New bird for me in 2021.
