WThe calliope hummingbird is the smallest bird native to the United States and Canada. It has a western breeding range mainly from California to British Columbia, and migrates to the Southwestern United States, Mexico, and Central America for its wintering grounds. It was previously considered the only member of the genus Stellula, but recent evidence suggests placement in the genus Selasphorus. This bird was named after the Greek muse Calliope. The former genus name means "little star".
WThe New Holland honeyeater is a honeyeater species found throughout southern Australia. It was among the first birds to be scientifically described in Australia, and was initially named Certhia novaehollandiae.
WHummingbirds are birds native to the Americas and constituting the biological family Trochilidae. They are the smallest of birds, most species measuring 7.5–13 cm (3–5 in) in length. The smallest extant hummingbird species is the 5 cm (2.0 in) bee hummingbird, which weighs less than 2.0 g (0.07 oz). The largest hummingbird species is the 23 cm (9.1 in) giant hummingbird, weighing 18–24g (0.63–0.85 oz).
WThe ruby-throated hummingbird is a species of hummingbird that generally spends the winter in Central America, Mexico, and Florida, and migrates to Canada and other parts of Eastern North America for the summer to breed. It is by far the most common hummingbird seen east of the Mississippi River in North America.
WThe Réunion grey white-eye is a small passerine from the family Zosteropidae, which is native to the islands of Réunion.
WSunbirds and spiderhunters make up the family Nectariniidae of passerine birds. They are small, slender passerines from the Old World, usually with downward-curved bills. Many are brightly coloured, often with iridescent feathers, particularly in the males. Many species also have especially long tail feathers. Their range extends through most of Africa to the Middle East, South Asia, South-east Asia and southern China, to Indonesia, New Guinea and northern Australia. Species diversity is highest in equatorial regions.
WThe plain-backed sunbird, also known as blue-throated sunbird is a sunbird. The sunbirds are a group of very small Old World passerine birds which feed largely on nectar, although they will also take insects, especially when feeding young. Flight is fast and direct on their short wings. Most species can take nectar by hovering like a hummingbird, but usually perch to feed most of the time.
WThe Seychelles sunbird is a small passerine from the sunbird family. It is named after the French explorer Jean-Jacques Dussumier. It is native to the Seychelles, where it is known as kolibri in Seychellois Creole. This bird is placed in the genus Cinnyris by some authorities and in Nectarinia by others. Although this bird has a limited range, it is described as common and has a stable population, so the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
WThe yellow-rumped thornbill is a species of passerine bird from the genus Acanthiza. The genus was once placed in the family Pardalotidae but that family was split and it is now in the family Acanthizidae. There are four subspecies of yellow-rumped thornbill. It is a small, brownish bird with a distinctive yellow rump and thin dark bill. It inhabits savannah, scrub and forests across most of Australia and eats insects. The species engages in cooperative breeding.
WTrochilinae is a subfamily of the hummingbird family (Trochilidae). Members of the subfamily Trochilinae are sometimes called typical hummingbirds. They typically display iridescent plumage in metallic reds, oranges, greens and/or blues. Strong sexual dimorphism in plumage and size is evident in many species.
