Selas

Selas, also known as "Selasphorus", is a genus of hummingbirds in the family Trochilidae. These small, vibrantly colored birds are primarily found in the Americas, ranging from North America down to South America. The genus currently contains several species, though taxonomic classifications can sometimes vary.

A key characteristic of selas hummingbirds is their rapid wingbeats, which enable them to hover in mid-air and fly backward, a feat common to all hummingbirds. Their long, slender beaks are adapted for feeding on nectar from flowers, playing an important role as pollinators. They also supplement their diet with small insects and spiders, providing essential protein.

Species within the selas genus are often distinguished by their plumage, particularly the iridescent gorget (throat patch) of the males, which can display a dazzling array of colors. Females typically have more subdued coloration. Their nesting habits are also typical of hummingbirds, with small, cup-shaped nests constructed from plant down, spider silk, and lichen.

The behavior of selas hummingbirds can include territoriality, with males often defending flower patches or feeders aggressively. Their migratory patterns vary by species, with some undertaking long-distance journeys between breeding and wintering grounds. Conservation status for selas species ranges from Least Concern to more vulnerable categories, depending on population trends and habitat availability.
