Description of the Bird

This bird was a tanager based on structure, bill shape, and bird size.

The bill was very heavy, long, and light gray with dull yellow at the tip. wings were gray with only a hint of a wing bar. The head appeared crested. The throat was mustard yellow and the brightest part of the undersides. A light yellowish wash covered the rest of the undersides. Legs were grayish. Tail was dull greenish.
Behaviors: Foraged on the ground near a corral. Perched repeatedly on a metal fence.
Call: non heard
Plumage: althernate

Similar Species Discussion

This was the eastern rubra race of Summer Tanager identified by lack of tail wagging and reddish coloration on its face.

From Northern Hepatic Tanager, Piranga flava dextra by bill color -much lighter on this bird than the darker gray bill of Northern Hepatic Tanager and lack of gray auriculars found in HETA.

From Scarlet Tanager female by light gray wings, unlike black wings of SCTA and by bill length and color, unlike the short darker gray bill of SCTA

From other Piranga Tanagers by the lack of wingbars.

Previous Experience

Not too much exerience with eastern summer tanager. Quite a bit with the western summer tanager from when I lived in SE AZ. Probably more familiar with Northern, Lowland, and Highland Hepatic Tanagers from AZ, and South America
