Here, the measurement of length, wing, tail, tarsus, and two forms of culmen measurement are shown. Bird measurement or bird biometrics are approaches to quantify the size of birds in scientific studies. The variation in dimensions and weights across birds is one of the fundamental sources of diversity among birds, and even Within species ...
Bird wing. The skeleton of a bird wing. Places of attachment of various groups of flight feathers are indicated. Bird wings are a paired forelimb in birds. The wings give the birds the ability to fly, creating lift. Terrestrial flightless birds have reduced wings or none at all (for example, moa). In aquatic flightless birds (penguins), wings ...
Wing chord is an anatomical measurement of a bird 's wing. The measurement is taken with the wing bent at a 90-degree angle, from the most prominent point of the wrist joint to the most prominent point of the longest primary feather. It is often taken as a standard measurement of the proportions of a bird and used to differentiate between ...
The distance A to B is the wingspan of this Boeing 777-200ER. The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the opposite wingtip. For example, the Boeing 777–200 has a wingspan of 60.93 metres (199 ft 11 in), [1] and a wandering albatross (Diomedea exulans) caught in 1965 had a wingspan of 3.63 metres (11 ft 11 in), the official record for a living ...

Birdwing. Birdwings are butterflies in the swallowtail family, that belong to the genera Trogonoptera, Troides, and Ornithoptera. Most recent authorities recognise 36 species, however, this is debated, and some authorities include additional genera. Birdwings are named for their exceptional size, angular wings, and birdlike flight.
They range in size variably, but on average measure 53–64 cm (21–25 in) in length, have a wingspan of 103–117 cm (3.38–3.84 ft) and weigh 0.63–1.4 kg (1.4–3.1 lb). [54] The Henst's goshawk (Accipiter henstii) and Meyer's goshawk (Accipiter meyerianus) do rival it in terms of wing size and body mass.
As with wing formulae, this measurement is useful for distinguishing between similarly plumaged birds; however, unlike wing formulae, it is not necessary to have the bird in-hand to make the measurement. Rather, this is a useful relative measurement—some species have long primary extensions, while others have shorter ones.
