Anna's Hummingbird

The shiny feathers on a hummingbird's throat is called their gorget. The gorget on a male Anna's Hummingbird is a beautiful bright red and also extends onto the top of its head. These feathers are iridescent and the birds are able to aim a beam of light from them. That's why the gorget looks black until they notice you and then you see the color. Interestingly, the female Anna's hummer often has a small gorget, often diamond-shaped. The females of most other species have no gorget at all.
