Long-crested Eagle numbers have declined by 94 per cent in Kenya.
Α team of Kenyan and international scientists has reported severe declines of Kenya's birds of prey over the past 40 years. In a study published in Biological Conservation, scientists from Kenya, the UK, France and the USA have recorded the first nationwide trends for Kenya's raptors.
Kenya's diurnal raptors were first surveyed in the 1970s by identifying and counting individuals while driving along roads, both inside and outside protected areas. These roadside surveys were repeated multiple times during the 2000s. Of 22 species examined, 19 were seen less frequently during the recent period and the median rate of the decline was -70 per cent. Some of Kenya's most iconic raptors have almost disappeared.
The largest declines were recorded in Secretarybird and Long-crested Eagle -94 per cent; Common Kestrel -95 per cent; Lesser Kestrel -93 per cent; Augur Buzzard -91 per cent; and Hooded Vulture and Montagu's Harrier, both -88 per cent.

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.
