Hummingbirds are known for their small size, long, thin bills, and amazing agility in flight.
( Campbell and Lack, 1985 Sargent and Sargent, 2001 Schuchmann, 1999 ) There are also some agricultural crops, such as banana and coffee that can support hummingbirds. Hummingbirds can be found in habitats from coastal areas at sea level to mountainous areas at an elevation of 5000 m.ĭue to the prevalence of hummingbird feeders and cultivated gardens, hummingbirds can sometimes be found in urban and suburban areas with few natural food sources. This requirement is satisfied in a number of different habitats: arid scrub, desert oasis, coastal lowland, tropical rainforest, Neararctic pine forests, and alpine tundra. The main habitat requirement for hummingbirds is a large number of nectar producing flowers. Hummingbirds feed and nest in a wide variety of terrestrial habitats, both temperate and tropical. ( Campbell and Lack, 1985 Schuchmann, 1999 Tyrrell and Tyrell, 1985) More than half of all species of hummingbird are found in Brazil and Ecuador. Most species are tropical and sub-tropical and live between 10 degrees N and 25 degrees S lattitude. Their range extends from Alaska to Labrador in the North to Tierra del Fuego in the south and from Barbados to the Juan Fernandes islands. Hummingbirds are found only in the New World in the Nearctic and Neotropics. ( Campbell and Lack, 1985 Gill, 1995 Schuchmann, 1999) Geographic Range Hummingbirds are found in a variety of habitats and while their range includes much of the New World, most hummingbird species are Neotropical. This is especially important for those species found at high elevation where nighttime temperatures can dip below freezing. Known for their small size (the smallest species of hummingbird weighs 2 g), rapid wing movements and heartbeat, hummingbirds can compensate for their high energetic requirements by going into torpor during cold nights. Male hermits display together in large groups called leks while trochilines are mainly territorial their courtship often involves dramatic aerial displays. Some male hummingbirds have elaborate ornamentation such as elongated tail feathers and iridescent crests. Most hummingbird species are polygynous (males mate with more than one female) and are sexually dimorphic (sexes do not look alike) males (especially trochilines) often have bright iridescent feathers while females have more cryptic coloration. They have evolved unique characteristics such as narrow elongated beaks, extendable tongues and hovering flight, all of which allow them to exploit nectar resources. Hummingbirds feed primarily on the nectar of flowers and supplement their diet with small insects. The hummingbird family is divided into two sub-families: Phaethornithinae (hermits) composed of 34 species and a larger group, Trochilinae (trochilines or "typical" hummingbirds), with 294 species. Although the number of genera and species in this group changes continually, currently there are 102 recognized genera and 328 species of hummingbirds. The family Trochilidae belongs to its own Suborder, Trochili.
