Most kinds of bird wings can be grouped into four types, with some falling between two of these types. These types of wings are elliptical wings, high-speed wings, high aspect ratio wings and soaring wings with slots. The short and rounded (elliptical) wings of the Blue Jay are adequate for short flights in densely-vegetated habitats.
Most kinds of bird wing can be grouped into four types, with some falling between two of these types. These types of wings are elliptical wings, high speed wings, high aspect ratio wings and slotted high-lift wings. [25] The budgerigar's wings, as seen on this pet female, allow it excellent manoeuvrability.
Smith's longspur (Calcarius pictus) is a bird from the family Calcariidae, which also contains the other species of longspurs. A bird of open habitats, it breeds in northern Canada and Alaska, and winters in the southern United States. Primarily a ground-feeding seed-eater, it supplements its diet with insects in the summer.
When roosting on the ground during the day, this medium-sized (20–23 centimetres (7.9–9.1 in) long) nightjar is mainly variegated grey, with a browner collar. It has a shadowy form with easy, silent moth-like flight; this nightjar is relatively short-tailed, and lacks white in the wings or tail. The song is a churring trill. [1]

By shaking its wings 100 times a second, the club-winged manakin can produce around 1,400 single sounds during that time. [5] In order to withstand the repeated beating of its wings together, the club-winged manakin has evolved solid wing bones (by comparison, the bones of most birds are hollow, making flight easier).
