African Pygmy Goose Scientific Name: Nettapus Auritus Class: Aves Order: Anseriformes Family: Anatidae African Pygmy Goose Scientific Name: Nettapus auritus Class: Aves Order: Anseriformes Family: Anatidae The African Pygmy Goose is a perching duck from the sub-Saharan Africa area. They are the smallest of Africa’s wildfowl, and one of the smallest in the world. The average weight of a male is 285 grams (10.1 oz) and for the female 260 grams (9.2 oz). Their wingspan is between 142 millimeters (5.6 in) to 165 millimeters (6.5 in). The African pygmy goose has a short bill which extends up the forehead so they resemble geese. The males have a white face with black eye patches. The iridescent black crown extends down the back of the neck. The upper half of the fore neck is white whereas the base of the neck and breast are light chestnut colored. The sixteen tail feathers are black. The wing feathers are black with metallic green iridescence on the coverts. Range The African pygmy goose is found in sub-Saharan Africa and Madagascar. They are known to be nomadic. Habitat They live in slow flowing or stagnant water with a cover of water lilies. This includes inland wetlands, open swamps, river pools, and estuaries. Gestation The female lays 6 to 12 eggs that are incubated for 23 to 26 days. Litter There is usually between 6 and 12 young with each mating. Behavior They live in strong pair bonds that can last over several seasons and their breeding is triggered by rains. Reproduction The African pygmy goose will nest in natural hollows or disused holes of barbets and woodpeckers in trees standing in or close to the water. They have strong pair bonds that may last over several breeding cycles. The move to mate is triggered by the rains which increases the food supply to the parents and young. Wild Diet The African pygmy goose eats predominantly the seeds of water lilies, seeds, and vegetative parts of aquatic plants. They also may eat aquatic insects and small fish. .

Oromia is the largest National Regional State of Ethiopia. Here we present the first comprehensive checklist of its birds. A total of 804 bird species has been recorded, 601 of them confirmed (443) or assumed (158) to be breeding birds. At least 561 are all-year residents (and 31 more potentially so), at least 73 are Afrotropical migrants and visitors (and 44 more potentially so), and 184 are Palaearctic migrants and visitors (and eight more potentially so). Three species are endemic to Oromia, 18 to Ethiopia and 43 to the Horn of Africa. 170 Oromia bird species are biome restricted: 57 to the Afrotropical Highlands biome, 95 to the Somali-Masai biome, and 18 to the Sudan-Guinea Savanna biome.

  • Population Sizes of Cotton Pygmy-Goose Nettapus Coromandelianus Coromandelianus Gmelin in Some Places of Assam (India)

K. Department of Zoology, T. H. B. College, Karchantola, Sonitpur (Assam), PIN-784189, India. Accepted 29 November, 2011 The breeding season is of paramount importance to the population size of waterfowl. All of the increase in population size occurs, as does much of the mortality during that season, which is often but a fraction of the entire year. Population of a species is indicative of the environmental factors of that area which strictly influences the species. The study includes the population size of the Cotton Pygmy- goose Nettapus coromandelianus coromandelianus Gmelin, a least concern anatid of South-east Asia and near relatives of Pygmy-goose of New South Wales which is under threatened condition. The study also includes the parameters influencing the population sizes. Two hundred and three (203) Cotton Pygmy-geese were observed during breeding season in 2006 and 2009 in study sites of Assam. Adult survival rates were found high 0.99 to 0.94 (SE < 0.005), but duckling survival was much lower, varying from approximately 0.1 to 0.3 during 2007 to 2009. No naturally died specimens have been collected during the study period, but 7 specimens have been reported to be killed by hunters among a total of 22 gooses were killed during 2006 to 2008.

  • A New Anseriform Genus and Species from the Nebraska Pliocene
    A NEW ANSERIFORM GENUS AND SPECIES FROM THE NEBRASKA PLIOCENE LESTER L. SHORT AMONGavian fossilson loan to me from the University of Nebraska State Museumis the tarsometatarsusof a goose-likeanseriform bird from the early Plioceneof Nebraska. The tarsometatarsushas somefeatures of geeseand swans,and of the anatinetribe Tadornini,but it alsotends somewhattoward the Cairinini in someof its features. Comparisonwith extant and fossilAnseriformes in the American Museum of Natural History and the United States National Museum and a study of the literature have convincedme that this tarsometatarsusrepresents an undescribed speciesthat is sufficientlydistinct to warrant placementin a new genus. I thank the authoritiesof the above-mentionedmuseum for their help in conductingmy studies.I am gratefulto CharlesG. Sibley,who originally borrowedthe fossil,for permissionto studyit. It is a pleasureto acknowl- edgethe aid of C. B. Schultzfor the loan of the material, and H. B. Gundersonof the Universityof NebraskaState Museumfor usefulinfor- mationconcerning the fossil. The use and potential importance of stereophotographyin avian paleontologyhas beendiscussed by Cracraft (1968: 3-4).
