Black-backed Oriole
Even though it's only February, we might already have a winner for the least expected ABA Area vagrant for 2017.

On January 31st a resident of Berks County, Pennsylvania, noticed and photographed a strange oriole in their yard.

The bird was posted to the Advanced Bird ID Facebook group where it was quickly identified as a Black-backed Oriole, a central Mexican endemic.

Pending acceptance this is a potential 1st ABA Area record.

The bird is being seen at 20 and 21 Indiana Ave, Sinking Spring, Berks County, Pennsylvania.

This is just northwest of Philadelphia.
