Behaviour
Flight is a mixture of a slow, deep flapping and short glides: unlike their European namesakes, White-winged Choughs are not particularly strong or agile fliers and spend the great majority of their time on the ground, foraging methodically through leaf litter for worms, insects, grain, and snails in a loose group, walking with a distinctive swagger, and calling softly to one another every few seconds. A rich find is the cause of general excitement and all come running in to share in it. The family group walks several kilometers each day through its large territory, foraging as it goes, taking to the air only if disturbed.
Choughs are territorial and highly social, living in flocks of from about 4 up to about 20 birds, usually all the offspring of a single pair. Because raising of young is a group effort bands of chough may kidnap fledglings from other family groups so that they will be able to help them to raise their chicks next year.

Famous quotes containing the word behaviour:
“... into the novel goes such taste as I have for rational behaviour and social portraiture. The short story, as I see it to be, allows for what is crazy about humanity: obstinacies, inordinate heroisms, “immortal longings.””
—Elizabeth Bowen (1899–1973)
“When we read of human beings behaving in certain ways, with the approval of the author, who gives his benediction to this behaviour by his attitude towards the result of the behaviour arranged by himself, we can be influenced towards behaving in the same way.”
—T.S. (Thomas Stearns)
“The methodological advice to interpret in a way that optimizes agreement should not be conceived as resting on a charitable assumption about human intelligence that might turn out to be false. If we cannot find a way to interpret the utterances and other behaviour of a creature as revealing a set of beliefs largely consistent and true by our standards, we have no reason to count that creature as rational, as having beliefs, or as saying anything.”
—Donald Davidson (b. 1917)
