Description of the Bird
The bird was observed on the feeder just outside our kitchen window. The binoculars were 3 meters from the bird as it perched at the feeder. The bird was observed seven times, by both my wife and myself, to make a positive identification.
The streaked rosy gorget (Sibley) was diagnostic.
Behaviors: The species most commonly frequenting the feeder are black-chinned females and an occasional rufous female. This calliope male interacted with black chinned females by flying from the feeder to perch on the adjacent clothesline in proximity to a perched black-chinned. This allowed a definitive size comparison between the two species.
Similar Species Discussion
The size comparison, coupled with the green crown and the streaked rosy gorget, clearly separated it from a female black-chinned.
The Sibley Field Guide to Birds of Western North America (pg. 261). The guide was used as we observed the bird.
My wife and I have been birders since 1975, had a backyard feeder for 3 years, and have enjoyed the close viewing of the hummers each summer.
