The cinnamon hummingbird (Amazilia rutila) is a species of hummingbird in the "tribe of the emeralds", Trochilini. Currently, four regional subspecies are recognized. It is predominantly found along the Pacific western coast of Mexico and south through Guatemala, El Salvador, Honduras, Nicaragua and Costa Rica, with some also residing in Belize and the southern Mexican states of Campeche, Quintana Roo and Yucatán. Cinnamon hummingbirds are typically found at or just slightly above sea level, often inhabiting coastal and lowland areas, as well as further inland in warmer locations in the southern parts of their range. The hummingbird has a length of approximately 9.5 to 11.5 centimetres (3.7 to 4.5 in), and on average weighs about 5 to 5.5 grams (0.18 to 0.19 oz). Its diet usually consists of food foraged from the understory to the mid-story, but it will also visit taller flowering trees. The cinnamon hummingbird feeds on nectar from a very wide variety of flowering plants and also eats insects. It is a territorial species, defending its feeding sites from intrusion by other hummingbirds, bees, and butterflies. This cinnamon hummingbird feeding from a flower in flight was photographed in Los Tarrales Natural Reserve near Patulul, Guatemala.
