Female/immature hummingbird photos

[David Tønnessen]

Greetings Colorado Birders,

I am requesting good images of immature/female hummingbirds of the following species:

Broad-tailed Hummingbird

Rufous Hummingbird

Calliope Hummingbird

Black-chinned Hummingbird

The photos will be used in a field identification article in Colorado Birds. Photographers will of course be credited and contributions much appreciated.

Thank you, and happy spring!
