Lesser flamingos flying in formation. When in gliding flight, the upward aerodynamic force is equal to the weight.In gliding flight, no propulsion is used; the energy to counteract the energy loss due to aerodynamic drag is either taken from the potential energy of the bird, resulting in a descending flight, or is replaced by rising air currents ("thermals"), referred to as soaring flight.
The great white pelican rivals the kori bustard, which has even more pronounced sexual dimorphism, as the heaviest flying bird to reside in Africa (both averaging perhaps slightly heavier than the cape vulture and the wattled crane). There are a small few slightly heavier flying birds in the Eurasian portions of the range.
Most birds have approximately 175 different muscles, mainly controlling the wings, skin, and legs. Overall, the muscle mass of birds is concentrated ventrally. The largest muscles in the bird are the pectorals, or the pectoralis major, which control the wings and make up about 15–25% of a flighted bird's body weight.
Description. The Rüppell's vulture is a large vulture, noticeably outsizing the closely related white-backed vulture, with which they often occur in the wild. Adults are 85 to 103 cm (33 to 41 in) long, [3][6] with a wingspan of 2.26 to 2.6 m (7 ft 5 in to 8 ft 6 in), and a weight that ranges from 6.4 to 9 kg (14 to 20 lb). [3][7][8] Both ...
[16] [17] However, other sources claim a mean species body mass of 10.3 kg (23 lb) for the Andean condor. [18] The Andean condor is the largest living land bird capable of flight if measured in terms of average weight and wingspan, although male bustards of the largest species (far more sexually dimorphic in size) can weigh more.
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]
Snowy albatross. The snowy albatross (Diomedea exulans), also known as the white-winged albatross, wandering albatross, or goonie, is a large seabird from the family Diomedeidae; they have a circumpolar range in the Southern Ocean. It is the most recently described species of albatross and was long considered to be the same species as the ...
Kori bustard. The kori bustard (Ardeotis kori) is the largest flying bird native to Africa. It is a member of the bustard family, which all belong to the order Otidiformes and are restricted in distribution to the Old World. It is one of the four species (ranging from Africa to India to Australia) in the large-bodied genus Ardeotis.
