Male and Female Black-chinned – These slender hummers are comparatively small with dull, metallic green backs, flat foreheads and long bills. Males are identified by an iridescent purple band present underneath a black chin. Females often have a grayish crown with dull gray underparts.
Immature Male Anna’s – These rare visitors are medium-large sized and stocky with a short black bill. Immature males often exhibit a throat patch and face that is speckled with iridescent rosy-pink. Notice the lack of any cinnamon wash on the body or rufous on the tail? This distinguishes the juvenile male Anna’s Hummingbird from Rufous Hummingbirds.
Male Magnificent – The iridescent purple crown and equally striking green gorget easily distinguish the large, long-billed male Magnificent Hummingbird from the other visitors on camera.
Male Calliope – These tiny birds are the smallest you’ll see north of Mexico in North America. The male Calliope exhibits a streaky magenta and white throat pattern combined with green upperparts and short, thin bill.
Male and Female Rufous – The male Rufous Hummingbird is named for its color. The brilliant orange face, sides and back, combined with the vivid red-bronze gorget set these pugnacious individuals apart from the rest. Females are equipped with an iridescent reddish spot in the center of the throat. These medium-sized female hummingbirds have buffy rufous sides, green heads and backs, and whitish bellies.
