Other Birds of Note
Smallest Bird - Male bee hummingbirds (mellisuga helenae), which live in Cuba, weigh 0.056 ounces and are 2.75 inches in length. The bill and tail account for half of this length.
Smallest Bird of Prey - The black-legged falconet ( Micrphierax fringlius ) of southeast Asia and the white-fronted or Bornean falconet ( M. latifrons ) of northwestern Borneo both have an average length of 5.5-6 inches, including a 2 inch tail, and weigh approximately 1.25 ounces.
Smallest Parrot - The Pygmy parrots of Papua and nearby islands. Genus Micropsitta. There’s six different sorts - Yellow-capped, Buff-faced, Finsch’s, Geelvink, Meek’s, Red-breasted - all around 3" long (8cm). Thought to eat lichens and mosses but not much is known about their lifestyles.
Fastest Swimming Bird - Gentoo Penguin found on the Antarctic Islands can swim 40 km per hour. Large populations are found at South Georgia, Falkland Islands, and Iles Kerguelen although their breeding distribution is circumpolar. An orange bill and a white stroke behind its eye distinguish the black and white gentoos from the smaller adelie and chinstrap species. Long stiff tail feathers stick out behind as they walk, often cocked up in the water, no other penguin has such a prominent tail. They breed in winter at the more northerly sub-Antarctic islands, laying two eggs as early as July. Can dive over 300’ though most prey dives are shallower. Most dives last only half a minute.
Biggest Carnivorous Bird - Titanis Walleri. This bird is known from the early Pleistocene (Ice Age) of Florida. It is the last known member of the family Phorusrhacidae, a group of large, flightless birds which evolved in South America. This creature had an estimated body height of 3 meters (if it stood fully erect, and 2.5 meters in more normal situations). Titanis really had arms instead of wings.
Heaviest Flying Birds - The Kori Bustard or paauw (Ardeotis Kori) of northeast and southern Africa and the great bustard (Otis tarda) of Europe and Asia weigh about 40-42 pounds. There is a report of a 46 lb. 4 oz. male great bustard shot in northeastern China. It was too heavy to fly.
Heaviest Birds of Prey - Andean condors (Vultur gryphus) are the heaviest species of bird of prey. Males weigh 20-27 pounds and have a wingspan of at least 10 feet. A male California condor (Gymnogyps californianus) preserved in the California Academy of Sciences is reported to weigh 31 pounds. It is rare for the species to exceed 23 pounds in weight.
Longest Feathers - The phoenix fowl or Yokohama chicken (a strain of the red junglefowl Gallus is bred in Japan for ornamental purposes. A rooster with a 34 ft. 9.5 in. Tail covert was reported in 1972.
Longest Bills - The bill of the Australian pelican (Pelicanus conspicillatus) is 13-18.5 inches long. The longest beak in relation to body length is that of the sword- billed hummingbird ( Ensifera ) of the Andes. At 4 inches, the beak is longer than the bird’s body (excluding the tail).
Biggest Bird - The largest and strongest living bird is the North African ostrich (Struthio camelus . Males can be up to 9 feet tall and weigh 345 pounds, and when fully grown the have one of the most advanced immune systems of any animal. South Africa was the first country to see the commercial potential of ostrich products - the creature are prized not only for their large soft white feathers and their meat but also for their skins, which are made into the strongest commercially available leather in the world. Ostrich farming is believed to have begun in the Karoo and Eastern Cape c. 1863. By 1910 there were more than 20,000 domesticated ostriches in the country, and by 1913 ostrich feathers were the fourth most important south African export product. Demand began to dry up soon afterwards, but there was an ostrich revival in the 1920’s when farmers started to produce biltong ( dry strips of ostrich meat) commercially.
Biggest Seabird - The Northern Royal Albatross (Diomedea epomophora sanfordi) with a wing span 3 metres, flight speed up to 115 km/h. 80% of life spent at sea. White body, black on backs of wings.
