It is described as having a bright olive green plumage with a gray belly and a little purple on the wings and rump. A hummingbird’s brain is 4.2% of its weight, which is the largest proportion in the bird kingdom. Young birds of either sex may have brownish edges on otherwise green body feathers--especially on the crown and back (above). As she noted this hummingbird was slightly smaller than a Ruby-throated hummer and its entire body was black. When a young male returns the following spring, some researchers believe his gorget may have an irregular bottom edge (below), and one or more of the throat feathers may be brownish instead of red; this may be a useful ageing characteristic but needs further study. For details about these unusual plumages, click on the photo below.

Adult Ruby-throated Hummingbirds, Archilochus colubris, are sexually dimorphic; i.e., the adult male and adult female are different in external appearance. It has no sense of smell, but its eyesight and hearing ability is far better than humans.

It's found in almost all the states in the US and in many provinces in Canada. What kind of bird has a black head and throat, with a white ring around it's neck with a grey chest, body and wings? Older females occasionally have one or two black throat feathers (below); very, very rarely they may have a single red feather on the throat. I live in northern California, Sonoma county.
