Although some closely related species of hummingbirds (like Anna's and Costa's) interbreed occasionally, the combination of Violet-crowned (Amazilia violiceps) and Broad-billed (Cynanthus latirostris) is so rare that it has only been documented once before.

This unique bird was discovered a couple years ago at Boyce Thompson Arboretum where it continues to be seen regularly.

These photos were taken on December 18, 2007 and September 23, 2007.
