Most African vultures depend pri-marily on the kills made by large carnivores for their food.
This perhaps best applies to those birds that spend their time within naturally functioning wild areas where large carnivores still live and flourish. Rüppell’s, White-backed, Lappet-faced, White-headed and Hooded vultures, as well as Tawny Eagles and Black Kites, routinely feed in this way. Scavenging from a kill made by another animal is an excellent strategy as the birds are able to feed on a high-protein food source without having to expend energy or expose themselves to the risk that comes with subduing large prey.

WATER IS LIFE. As wildlife photographer Greg du Toit knows better than most.
winter wanderer
as summer becomes a memory in the south, the skies are a little quieter as the migrants have returned to the warming north. But one bird endemic to the southern African region takes its own little winter journey.

Southern SIGHTINGS
The late summer period naturally started quietening down after the midsummer excitement, but there were still some classy rarities on offer for birders all over the subregion. As always, none of the records included here have been adjudicated by any of the subregion's Rarities Committees.
flood impact on wetland birds
One of the features of a warming planet is increasingly erratic rainfall; years of drought followed by devastating floods. Fortunately, many waterbirds are pre-adapted to cope with such extremes, especially in southern Africa where they have evolved to exploit episodic rainfall events in semi-arid and arid regions. But how do waterbirds respond to floods in areas where rainfall - and access to water - is more predictable? Peter Ryan explores the consequences of recent floods on the birds of the Western Cape's Olifants River valley.
