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 ...
The table contains a list of the largest birds living on this planet by wingspan, at maximum, assumed to be reliable by experts and verified records, at least 3 m (9 ft 10 in). Rank Image
In bird flight aerodynamics, the area of interest is the total wing area, that is, the area of both wings plus the area of the intervening portion of the body known as the "root box". [10] The root box is estimated from a measurement of the wing width at the base (the root chord ) and the difference between the wingspan and two times the extent ...
The largest bird of all time was likely the elephant bird Aepyornis maximus, which was estimated to have weighed 275–1,000 kilograms (610–2,200 lb) and stood at 3 metres (9.8 ft) tall. [4] [5] The largest wingspan of all time likely belonged to Pelagornis sandersi at roughly 5.2 m (17 ft). [6]
[14] [19] [20] The mean wingspan is around 283 cm (9 ft 3 in) and the wings have the largest surface area of any extant bird. [20] It has a maximum wingspan of 3.3 m (10 ft 10 in). [21] Among living bird species, only the great albatrosses and the two largest species of pelican exceed the Andean condor in average and maximal wingspan. [20] [22]
The wingspans of the largest great albatrosses (genus Diomedea) are the largest of any bird, exceeding 3.40 m (11.2 ft), although the other species' wingspans are considerably smaller, at as low as 1.75 m (5.7 ft). [20] The wings are stiff and cambered, with thickened, streamlined leading edges.
The species also has the second-largest average wingspan of any North American bird, after the California condor. This large wingspan allows the bird to easily use soaring flight for migration. Body weight can range between 7.7 and 30 lb (3.5 and 13.6 kg), although typically these birds average between 11 and 20 lb (5.0 and 9.1 kg). [10]
The Laysan albatross is normally a silent bird, but on occasion may be observed emitting long "moo"-ing sounds, descending whinnies, or rattles. [6] Female Laysan albatrosses may bond for life and cooperatively raise their young. [8] A female Laysan albatross named Wisdom is the oldest known wild bird in the
