SCIENTIFIC NAME: Rhodopis vesper

Oasis Hummingbird

The Oasis Hummingbird is a species of hummingbird in the family Trochilidae.

It is a mid-sized hummingbird with an average length of 5.12 – 5.31 inches for an adult male and 4.33 –4.53 inches for an adult female.

They have an olive-green colored back and gray to white colored breast with a distinctive cinnamon colored rump. They have a long, decurved, black bill.

They are sexually dimorphic with males having a brightly iridescent gorget that is blue to red in color and a long, forked tail.

Females have much shorter tail feathers and no iridescent gorget.

Feed primarily on nectar as a source of energy. They are known to eat small invertebrates as well.

Subtropical or tropical dry shrubland, subtropical or tropical moist shrubland, and subtropical or tropical high-altitude shrubland.

Found in coastal regions of Peru in a 100–200 km wide strip that extends the length of Peru's coastline, about 3000 km.

It is also found in an adjacent population in Chile; a second disjunct population in coastal Chile exists 2000 km to the south, in a 75 by 200 km coastal strip.

As of now, little is known about the life cycle of the Oasis Hummingbird. Like most hummingbirds, the female is solely responsible for the incubation and rearing of the young while the male leaves immediately after copulation.

The incubation period is about 16 days and the nestling period about 27. The average clutch size is 2 eggs.
