The ruby -throated hummingbird (Archilochus colubris) is a species of hummingbird that generally spends the winter in Central America, Mexico, and Florida, and migrates to 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.
Description
This hummingbird is from 7 to 9 cm (2.8 to 3.5 in) long and has an 8 to 11 cm (3.1 to 4.3 in) wingspan. Weight can range from 2 to 6 g (0.071 to 0.212 oz), with males averaging 3.4 g (0.12 oz) against the slightly larger female which averages 3.8 g (0.13 oz). Adults are metallic green above and grayish white below, with near- black wings. Their bill, at up to 2 cm (0.79 in), is long, straight, and very slender. As in all hummingbirds, the toes and feet of this species are quite small, with a middle toe of around 0.6 cm (0.24 in) and a tarsus of approximately 0.4 cm (0.16 in). The ruby -throated hummingbird can only shuffle if it wants to move along a branch, though it can scratch its head and neck with its feet.The species is sexually dimorphic. The adult male has a gorget ( throat patch ) of iridescent ruby red bordered narrowly with velvety black on the upper margin and a forked black tail with a faint violet sheen. The red iridescence is highly directional and appears dull black from many angles.
