With the increase in the number of birders, new species have been added to the southern African bird list with surprising regularity over the past few years. A popular pastime among twitchers – often indulged in on long road trips to chase yet another vagrant – is to speculate what the next ‘mega’ to reach our shores will be. Another species to add to that list is the American CliffSwallow Petrochelidon pyrrhonota.
The 11 species of Petrochelidon swallows occur across the world, with five species in Africa, one in southern Asia, two in Australasia and three in the New World. In southern Africa we are familiar with the South African CliffSwallow P. spilodera, which breeds in colonies, mainly under bridges, in summer and migrates north to winter in central Africa.

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.
