The cinnamon hummingbird is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found from northwestern Mexico to Costa Rica. The cinnamon hummingbird is 9.5 to 11.5 cm (3.7 to 4.5 in) long and on average weighs about 5 to 5.5 g (0.18 to 0.19 oz). Adults of the nominate subspecies A. r. rutila have metallic bronze green upperparts and cinnamon to cinnamon rufous underparts that are paler on the chin and upper throat.
Scientific name: Amazilia rutila
Conservation status: Least Concern
Higher classification: Amazilia
The subspecies of cinnamon hummingbird are found thus:
A. r. diluta, the northwestern Mexican states of Sinaloa and Nayarit
A. r. graysoni, Isla María Madre in Islas Marías off the coast of western Mexico
A. r. rutila, from Jalisco in western Mexico south through El Salvador and western Honduras and Nicaragua into northwestern Costa Rica.
A. r. corallirostris, from Chiapas in Mexico south to El Salvador
The populations in Mexico's Yucatán state, northeastern Honduras, Nicaragua, and Costa Rica are usually attributed to A. r. rutila but have sometimes been considered to be part of A. r. corallirostris.
The cinnamon hummingbird inhabits primary and secondary deciduous and semi-deciduous forests and thorn forest. It ranges from sea level to about 1,600 m (5,200 ft) of elevation.
