Description of the Bird

Small hummingbird with green back, white belly, and bright red feathers around throat. Feathers on throat did not create a solid color but reminded me of the flames painted on some muscle cars.
Behaviors: Feeding at hummingbird feeder about 7:15 a.m. on 7/25/10. Flew to nearby deciduous tree briefly, then returned to feeder and then flew off.
Call: N/A
Plumage: green back, white belly red throat

Similar Species Discussion

Allen's hummingbird, but red on throat was brighter and not solid, but feathers appeared separately. Only hummingbird pictured that looked like that.
