From 1973 to 1976, I studied Black-faced Woodswallows
Artamus cinereus in the wheatbelt of Western
Australia, where the species is resident all the year round. By 1975 all the birds in one group were individually
colour-banded and their contributions at four nests were recorded during 68 hours of hide-watches. All birds,
presumably of both sexes, took part in incubating the eggs, and in brooding and feeding the nestlings.
