Archilochus alexandri
We get both Black-chinned Hummingbirds and Broad-tailed Hummingbirds during the spring and summer months. The Black-chinned have deep purple iridescent throat feathers when the sunlight hits them right, whereas the Broad-tailed Hummingbirds are red. Other pictures I have posted here don't show the pretty purple feathers, so I thought this was a good example.
