a rattling chirr-rr-rr-rr-rr". A. t. handleyi has the same color pattern as the nominate but is significantly larger and darker. A. t. fuscicaudata is smaller than the nominate and has a shorter and stouter bill. A. t. jucundas maxilla is pinkish brown rather than black; its belly is a darker gray than the nominate's and the bronze green on the tail is narrower. A. t. brehmi is similar to jucunda and fuscicaudata but has longer wings and tail. It has a longer bill than fuscicaudata and reduced green on the tail like jucunda. Distribution and habitat The subspecies of the rufous-tailed hummingbird are found thus: A. t. tzacatl, from the eastern Mexican states of Veracruz and Oaxaca south through Belize, Guatemala, Honduras, Nicaragua, and Costa Rica into most of Panama (It apparently skips El Salvador.) A. t. handleyi, Isla Escudo de Veraguas off the Caribbean coast of northwestern Panama A. t. fuscicaudata, the Cauca River and Magdalena River valleys of northern and western Colombia east into western Venezuela's Lara and Táchira states A. t. brehmi, the upper Güiza River in Colombia's Nariño Department A. t. jucunda, from Chocó Department in western Colombia south through western Ecuador to Loja Province The South American Classification Committee (SACC) of the American Ornithological Society extends the range of A. t. jucunda into Peru. The rufous-tailed hummingbird inhabits open, non-forested, landscapes such as clearings, gardens, and the edges of forest. It is also found in low, young, brushy, secondary forest. It frequently comes to feeders. In elevation the rufous-tailed hummingbird ranges from sea level to in Mexico, to in Costa Rica, in Colombia, and in Venezuela. It is found as high as in Ecuador but that elevation is thought be local or seasonal. Behavior Feeding Like most hummingbirds, the rufous-tailed feeds on nectar and small insects. It is common at sugar water feeders and often seen in coffee and banana plantations. It is extremely territorial and aggressive at feeding sites such as flower patches and feeders, from which it chases other hummingbirds and large insects. Breeding The rufous-tailed hummingbird is polygynous. Though it is aggressive while feeding, the species sometimes nests in loose colonies. Its breeding season varies widely across its range, but is within the February to November span. The female is entirely responsible for nest building, incubation of eggs, and care of nestlings. She lays two white eggs in a compact cup nest
