The foods of nesting and adult starlings (Sturnus vulgaris) poisoned by Lindane

Notornis, 34 (2), 89-94

Szlivka L. (1987)

Article Type: Paper

An accidental bird poisoning in May 1971 in the Obornjaca region, Yugoslavia, exterminated a starling colony. The food in 186 chick and 56 adult stomachs was analysed: more than 95% of the insects eaten were Orthoptera and Coleoptera, including many species harmful to agriculture. Differences in diet between the chicks and their parents may be explained by time of day or by the location in which adult birds foraged.











South Polar skua breeding colonies in the Ross Sea region, Antarctica

Notornis, 33 (3), 155-163

Article Type: Paper

Using ground and aerial surveys between 1980 and 1983, we increased the number of known breeding sites of the South Polar skua in the Ross Sea region from 21 to 55. Some 20 more sites may occur along parts of the coast which we did not survey, especially between Cape Adare and Cape Jones. We estimate that the Ross Sea region has about 15000 skuas. Up to 20% of breeders do not nest in association with penguins. Since the late 1950s, several colonies have increased, while others have decreased. Some colony changes have apparently been due to human activity. Information on banded birds indicates a low rate of exchange between colonies; some movement may be related to more food being available at refuse dumps at scientific bases.
