SAFRING and my training mentors strongly recommended that, having put a ring on a Cape Sugarbird’s leg, I should also record the state of the bird’s flight feathers. Initially I had no interest in doing this. I wanted to know where the birds were moving to, so recording the status of the bird’s feathers in terms of moult seemed to me a laborious duty.
Moult is typically recorded for each primary feather, but the demarcation between primary and secondary feathers is not always as distinct as one might hope. Most passerines begin the annual change of feathers at this intersection, but even with years of experience under my belt, I often find myself counting the feathers ‘backwards’, trying to determine where they theoretically meet. Then there’s the task of distinguishing old feathers from new. Trying to do so tests the skills of even the most seasoned ringers.

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.
