Copper-rumped

Common name: Copper-rumped Hummingbird
Scientific name: Saucerottia tobaci
Clades: Trochilini - Emeralds

The Copper-rumped hummingbird is 9 to 11 cm (3.5 to 4.3 in) long. Males weigh 4.6 to 4.7 g (0.16 to 0.17 oz) and females 3.5 to 4.2 g (0.12 to 0.15 oz).

In general, Copper-rumped Hummingbirds are fairly common small hummingbirds, and they are very territorial as well. It has a glossy green head and underparts, a coppery rump (absent in northwest mountain subspecies), a bronzy to rufous-brown undertail, and a medium bill with a red lower mandible. It also has a forked blue tail. A dull brown belly distinguishes the female from the male. It is usually found in second-growth forests, forest edges, and gardens. In flight, the bird sings a trill; in song, a slow, high-pitched four-note "e-ri-caa."
