Rk. Brooke et al., Breeding distribution, population size and conservation of the Greyheaded Gull Larus cirrocephalus in southern Africa, OSTRICH, 70(3-4), 1999, pp. 157-163
The Greyheaded Gull Larus cirrocephalus occurs throughout southern Africa,
both coastally and inland, and has bred at one time or another at 67 known
localities since the 1860s. Most of these sites have been occupied by small
numbers of birds, even single pairs, and for only one or a few years. The
two principal breeding areas are the East Rand in Gauteng and Lake St Lucia
in KwaZulu-Natal, both in South Africa. The next most important sites are
Walvis Bay, Namibia and Lake Ngami, Botswana. The total southern African br
eeding population is estimated as about 2000 pairs. The Greyheaded Gull is
not a threatened species in southern Africa, with 27 breeding sites support
ing more than half the breeding population within formally conserved areas.
