More than 20 years ago, at the start of the dry season in the parched rangelands of northern Namibia, a local farmer implicated Lappet-faced Vultures in the killing of his new-born dorper lambs.
He decided to exact presumed retribution and, although he’d been warned of its illegality, he laced two mammal carcasses with poison. The resultant carnage is forever testament to the chilling efficiency of poison as a des troyer in the bird world. Eighty-six Lappet-faced Vultures succumbed. The birds that did not perish immediately from the toxin were summarily shot where they crouched, incapacitated. The toll represented about 10 per cent of the total Namibian population of this species, eliminated at a single stroke. The current African population is estimated at some 8000 birds and the Usakos incident meant the loss of more than one per cent of the continent’s total – by one person, in one place, at one time.

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.
