‘We found that Grey Parrots voluntarily and spontane-ously help familiar parrots to achieve a goal, without obvious immediate benefit to themselves,’ says study coauthor Désirée Brucks of the Max Planck Institute for Ornithology, Germany.
Parrots and crows are known for having large brains relative to the size of their bodies and problem-solving skills to match. For that reason, they are sometimes considered to be ‘feathered apes’, explain Brucks and study coauthor Auguste von Bayern.
However, earlier studies showed that despite their impressive social intelligence, crows don’t help other crows. In their new study, Brucks and Von Bayern wondered: what about parrots?

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.
