Breeding

There is little information on the breeding biology of Oasis Hummingbird. Nests with eggs are reported from Chile from September through December (Johnson 1967), although it perhaps breeds throughout the year (Fjeldså and Krabbe 1990). The nest is a small cup suspended by the rim from a branch in a tree or shrub. The clutch is 2; egg dimensions are 13.8 x 9.2 mm (Johnson 1967). In captivity, the incubation period is ca 16 days, and the incubation is entirely by the female; the nestling period is ca 27 days (Hesse and Hesse 1986).
