Ruby-throated Hummingbirds are about 7 to 9 cm (2.8 to 3.5 in) long and have 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).
The Ruby-throated Hummingbird is a small hummingbird that inhabits woodlands and brushy habitats. A male's throat is ruby-red and his chin is black. There is almost no buffy tone on the underparts of the female (maybe a very light wash on the flanks). Sugar water feeders and flower gardens are common places where he can be found. The most common summer hummingbird in the eastern U.S. and Canada. Panama is where he spends the winter. Very difficult to differentiate from Black-chinned Hummingbirds, especially females and young males; thankfully the range overlaps only slightly. These subtle differences include a slightly brighter green upper surface, a shorter and straighter bill, and slightly narrower outer wing feathers.
