Hummingbirds are birds native to the Americas and comprise the biological family Trochilidae. With approximately 366 species and 113 genera, they occur from Alaska to Tierra del Fuego, but most species are found in Central and South America. About 28 hummingbird species are listed as endangered or critically endangered, with numerous species declining in population.
In biology, coevolution occurs when two or more species reciprocally affect each other's evolution through the process of natural selection. The term sometimes is used for two traits in the same species affecting each other's evolution, as well as gene-culture coevolution.
The 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 the most common hummingbird in eastern North America, having population estimates of about 35 million in 2021.
The black-chinned hummingbird is a hummingbird occupying a broad range of habitats. Its summer range is in the western United States and southwestern Canada. It is migratory, wintering as far south as Mexico. In sunlight, the gorget of iridescent purple feathers bordering its black chin is noticeable.
The 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".
The black-throated mango is a species in subfamily Polytminae of the hummingbird family Trochilidae. It is found in Panama, in every mainland South American country except Chile, and in Trinidad and Tobago.
The broad-tailed hummingbird is a medium-sized hummingbird species found in highland regions from western United States and Western Canada to Mexico and Guatemala.
The snowcap is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Costa Rica, Honduras, Nicaragua, and Panama.
The sword-billed hummingbird, also known as the swordbill, is a neotropical species of hummingbird from the Andean regions of South America. It is the only member in the genus Ensifera. Among the largest species of hummingbird, it is characterized by its unusually long bill, being the only bird to have a beak longer than the rest of its body, excluding the tail. It uses its bill to drink nectar from flowers with long corollas and has coevolved with the species Passiflora mixta. While most hummingbirds preen using their bills, the sword-billed hummingbird uses its feet to scratch and preen due to its bill being so long.
The volcano hummingbird is a species of hummingbird in tribe Mellisugini of subfamily Trochilinae, the "bee hummingbirds". It is found in Costa Rica and Panama. This hummingbird is the one that appears on the 20 thousand colones bill from Costa Rica.
In zoology, a nectarivore is an animal which derives its energy and nutrient requirements from a diet consisting mainly or exclusively of the sugar-rich nectar produced by flowering plants.
The lucifer sheartail or lucifer hummingbird is a medium-sized, 10 cm long, green hummingbird with a slightly curved bill and distinctive outward flare of its gorget feathers. Its habitat is in high-altitude areas of northern Mexico and southwestern United States. It winters in central Mexico.
The broad-billed hummingbird is a small-sized hummingbird that resides in Mexico and the southwestern United States. The bird displays sexual dimorphism, and the juveniles resemble the female adult more than the male adult. The broad-billed hummingbird is a bright coloured bird with a broad and bright red bill. The bird is also known for its other common names – the Colibrí Pico Ancho in Spanish and Colibri circé in French. It is a diurnal bird.
The horned sungem is a species of hummingbird native to much of central Brazil and parts of Bolivia and Suriname. It prefers open habitats such as savanna and grassland and readily occupies human-created habitats such as gardens. It recently expanded its range into southern Amazonas and Espírito Santo, probably as a result of deforestation; few other hummingbird species have recently expanded their range. The horned sungem is a small hummingbird with a long tail and a comparatively short, black bill. The sexes differ markedly in appearance, with males sporting two feather tufts ("horns") above the eyes that are shiny red, golden, and green. Males also have a shiny blue head crest and a black throat with a pointed "beard". The female is plainer and has a brown or yellow-buff throat. It is the only species within its genus, Heliactin.
The bumblebee hummingbird is a species of hummingbird in tribe Mellisugini of subfamily Trochilinae, the "bee hummingbirds". It is endemic to Mexico, but has occurred as a vagrant in the United States.
The Esmeraldas woodstar is a rare, neotropical species of hummingbird in the family Trochilidae. There are six different species in the woodstar genus. Most of them are poorly studied due to their small size, extremely similar resemblance to each other, and rarity. Esmeraldas woodstars are one of the smallest bird species. They are sexually dimorphic. The main difference between sexes is that males have a bright purple throat. Esmeraldas woodstars are found only on the Pacific coast of west Ecuador in semi-deciduous to evergreen forests. They feed on the nectar of flowering shrubs and trees. The main threat to this species is deforestation. Esmeraldas woodstars are Vulnerable and require habitat protection.
The black-bellied hummingbird is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Costa Rica and Panama.
The sapphire-throated hummingbird is a shiny metallic-green hummingbird found in Panama, Colombia, and more recently Costa Rica. The sapphire-throated hummingbird is separated into three subspecies; Chrysuronia coeruleogularis coeruleogularis, Chrysuronia coeruleogularis coelina, and Chrysuronia coeruleogularis conifis.
The buffy hummingbird is a species of bird in the hummingbird family Trochilidae. It is the only species placed in the genus Leucippus. This bird lives in dry forest and scrubland in northern South America where it feeds on insects and the nectar, flesh, and juice of cactus fruits.
The vervain hummingbird is a species of hummingbird in tribe Mellisugini of subfamily Trochilinae, the "bee hummingbirds". It is found on Hispaniola and Jamaica.
