Another great day at Cumbies last Sunday. A few more pictures to share. The third one is potentially an Audubon Warber which is the Western version of the Yellow-rumped warbler a rare sitting for Massachusetts. It is being confirmed by Wayne Peterson at Mass Audubon. Will update when I know more.
Here's the photographs of the unknown Warbler. There are many different markings that have completely thrown me off course. Clearly marked wing bars, yellow throat and belly, but white undertail. Darker crown and white eye ring. This time of year birds can have many odd coloration. I'll report back once I get confirmation from Mass Audobon.
