Global Range: (>2,500,000 square km (greater than 1,000,000 square miles)) BREEDING: south-coastal and southeastern Alaska, across much of Canada south through much of U.S. to central Mexico; also eastern Buenos Aires province, Argentina, in early 1980s (Ridgely and Tudor 1989); across Eurasia to Mediterranean region, northern Africa, China, Japan. NON-BREEDING: mainly South America, regularly from Costa Rica and West Indies to Tierra del Fuego (but in low numbers south of central Chile and northern Argentina, Ridgely and Tudor 1989); Africa and southern Asia; uncommon in Puerto Rico. Accidental in Hawaii.

Found in the southern savannah of Africa from southeastern Kenya, eastern Tanzania and Mozambique to Angola and southern Zaire, mainly in the Miombo Woodland Zone (5). The Critically Endangered giant antelope is confined to central Angola, where it is primarily located in the Luando Reserve and Cangandala National Park (3) (6).

Incredibly, the bateleur may spend as much as 80 percent of the day in flight, covering up to 500 kilometres, as it searches for food. Flying relatively low, this species scans the ground for signs of food and, when sighted, it descends in a tight spiral to investigate. It is particularly adept at locating carrion, often patrolling roadsides for roadkill, but it is an opportunistic feeder and quite capable of swooping down on live prey or catching birds in flight. The bateleur's broad diet consists of mammals, from shrews to small antelopes, and birds, from starlings to large hornbills, as well as reptiles, insects and dead fish (5). When not in flight, the bateleur can be seen perching on branches or standing on the ground with its wings outstretched, absorbing the heat from the sun (6). The bateleur's courtship is spectacular, and involves the male diving down upon the female while in flight, and making incredibly loud wing claps, audible over a great distance (5). This courtship behaviour helps to establish strong lifelong, bonds between the breeding pairs (6). The bateleur's breeding season varies according to location, occurring from September to May in West Africa, December to August in southern Africa and throughout the year in East Africa (5). The pairs establish a territory, which they actively defend from other bateleurs (6), and construct a robust nest from twigs lined with leaves in the fork of a tree, often near flowing water (5). A single egg is laid and incubated by the female for 52 to 59 days while the male guards the nest and brings food (5). Once hatched, the young take between 93 and 194 days to fledge, after which time they are permitted to stay in the pair's territory for a few months before being driven out (5) (6).

With its extensive range, and a global population estimated to be between 10,000 and 100,000 individuals, at present, the bateleur is not particularly imperilled (1). Nevertheless, in Kenya, Côte d'Ivoire, Namibia, Nigeria, South Africa, Sudan, Zimbabwe, parts of Zambia, and possibly parts of Tanzania the bateleur has undergone significant declines in population and range. This has been variously attributed to the consumption of poisoned carcasses used to control jackal populations (7), trapping for international trade, nest disturbance due to the expansion of human settlements, and the use of pesticides (1).

Distribucion en Costa Rica: Es una especie migratoria abundante durante el otoño (de comienzos o mediados de agosto hasta octubre) y la primavera (de comienzos de marzo a fines de mayo), a lo largo de ambas costas, y más esporádicamente en menor número a través de las bajuras de ambas laderas y hacia arriba a través del Valle Central. Es de poco común a rara en elevaciones mayores, aunque en ocasiones asciende hasta los 3000 m. Es una residente de invierno de distribución amplia, entre común y abundante localmente en ambas vertientes hasta cerca de los 1500 m. de altura. Unos pocos individuos observados en julio pueden ser migratorios tempraneros de otoño.
Distribucion General: Se reproduce desde Alaska y el norte de Canadá hasta la parte central de México. Invierna en forma regular desde Costa Rica y las Antillas hasta la Tierra del Fuego; hacia el norte casualmente se extiende hasta el sur de E.U.A. Goza de una amplia distribución en el Viejo Mundo.
Non-Migrant: No. All populations of this species make significant seasonal migrations.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: Yes. At least some populations of this species make annual migrations of over 200 km.
Arrives in much of U.S. in April, Alaska in May (Terres 1980). Common migrant in Puerto Rico and the Virgin Islands. Migrates through Costa Rica mainly early to mid-August through October and early March-late May or early June (Stiles and Skutch 1989). In South America mainly August to May (though some may linger throughout year) (Hilty and Brown 1986, Ridgely and Tudor 1989). See Turner and Rose 1989 for information on Old World migrations.
