Abstract

An adult female Wahlberg's Eagle from northern Namibia was tracked by satellite ovcr a total distance of 8816 km and located 104 times between 11 February and 4 November 1994. It migrated on an almost due north heading to northern Cameroon, north-eastern Nigeria and western Chad through the rain forest belt of the Congo and Zaire after the breeding season. The total trans-equatorial distance between the breeding and non-breeding ranges was 3520 km. During the non-breeding season the bird ranged over a large area (ca. 60 000 km2) for about six weeks (29 April - 14 June) in these three countries in a rather nomadic pattern covering a minimum distance of 1256 km. During two further months (14 June - 14 August) it restricted its movements to an area of about 50002 km near Maiduguri in the Sudan savannah of north-eastern Nigeria. The return migration took about two weeks longer than that to the north, which took about a month.
