22-3-2017 TROGON LODGE, COSTA RICA - RUBY THROATED HUMMINGBIRD (FEMALE) COURTESY MRS VALERIE FISHER


The Ruby-throated Hummingbird, Archilochus colubris, is a diminutive jewel, measuring a mere 7 to 9 cm in length with a wingspan stretching from 8 to 11 cm. These birds are a marvel of iridescence; the males boast a fiery ruby red throat patch, or gorget, which can appear black when not caught in the right light. Females, on the other hand, are more demure with white throats and a notched tail featuring a mosaic of green, black, and white.

To identify the Ruby-throated Hummingbird, look for the metallic green upperparts and the grayish white underparts. The male's unmistakable ruby-red gorget is bordered with black, while the female's throat may show faint streaks or spots. Their wings are near-black, and they possess a long, slender bill perfect for sipping nectar.

These birds favor deciduous and pine forests, forest edges, orchards, and gardens. They are adept at making their homes in a variety of environments, as long as there is a rich supply of nectar-bearing flowers.

The Ruby-throated Hummingbird breeds across eastern North America, from Canada down to Florida, and spends winters in Central America, Mexico, and the West Indies. They are known for their impressive migratory journey, which includes a nonstop flight across the Gulf of Mexico.
