Description

The wattled starling is 21 cm long, with a short tail and pointed wings. It has mainly grey plumage except for a white rump, and black flight feathers and tail. The breeding male has a white shoulder patch and a distinctive head pattern, with unfeathered yellow skin, and black forehead and throat wattles. The extent to which these seasonal features develop increases with the age of the bird and some old females may show a weaker version of this plumage. The non-breeding male has a feathered head except for a small yellow patch behind the eye. There are no wattles, but there is a black moustachial stripe. The white shoulder patch is much reduced. The female and juvenile plumages are similar to the non-breeding male, but the flight feathers and tail are brown. The black flight and tail feathers and white rump make this species unmistakable in flight. This species has a range of wheezing or grating calls comparable to those of the

Behaviour

Breeding

The wattled starling is a colonial breeder, and may share its colonies with the Cape weaver. It always nests in trees or bushes, including

at between 1 and 10 m above the ground. The globular nest is made from twigs and lined with grass or feathers. The two to five, usually three or four, eggs are pale blue, immaculate or with some brown spots, and are laid before the dome of the nest is completed. Both sexes build the nest, incubate the eggs and feed the young. The eggs hatch after 11 days, and the chicks leave the nest in another 13–16 days. They cannot fly, and suffer heavy predation from large

. Breeding is linked to an abundant insect supply, and colonies will be abandoned, even with chicks in the nest, if, for example, locust swarms are destroyed by control measures.

Roosting

The wattled starling is highly gregarious and will form large flocks, often with other starlings. Its reedbed roosts, which can be huge, may also be shared.
