All bird guides, hard copy and digital have range maps . . . a great way to identify a bird. If I’m not sure about my ID, I check the range maps to see if my bird belongs where I saw it.
None of that seems to work with the Red-bellied Woodpecker in Maine, as it doesn’t belong here (see the map below) but Ingrid and I see them quite regularity (including every day at our feeder one winter).
Got my first Red-bellied of the year this morning (Ingrid got one last week).
Lots of other great birds today.
