Ruby-Throated Hummingbird

Description:

The Ruby-Throated Hummingbird is 7–9 cm (2.8–3.5 in) long and has a 8–11 cm (3.1–4.3 in) wingspan. Weight can range from 2 to 6 g (0.071 to 0.21 oz), with males averaging 3.4 g (0.12 oz) against the slightly larger female which averages 3.8 g (0.13 oz).[3][4] Adults are metallic green above and greyish 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.[5][6]
