Similar Species Discussion

Structure and size and red coloring leaves us with just Hepatic Tanager, Summer Tanager, and Scarlet Tanager (lack of wing bars eliminates Western Tanager).

The dark bill gray highlights, and call of Hepatic Tanager eliminate it from consideration.

The dark wings and bill and the call of Scarlet Tanager eliminate it from consideration.
