Letter-winged Kites Elanus scriptus were found to be feeding predominantly on House Mice Mus musculus in north-eastern South Australia. In its normal central Australian range, the Letter-winged Kites diet has previously been recorded as consisting of native mammals, particularly the Long-haired Rat Rattus villosissimus. Potential ramifications of a major shift in dietary emphasis are discussed.
Brown Treecreepers have been banded and retrapped over a period of fifteen years as part of the Mount Mary Plains Survey in South Australia. Data were obtained on longevity, weight differences between the sexes, and fluctuations in local populations.
The diet of the Mistletoebird Dicaeum hirundinaceum was studied near Beerburrum, south-eastern Queensland. by examination of material voided by 92 birds over a three-year period. Between late December and June, the basic food of the few birds present in the area is fruit of the Viscaceous mistletoe Notothixos subaureus. Mistletoebirds congregate in the area between […]
We discuss a variety of methods of collecting information on the diets of birds, including observation, examination of faeces, emetics and stomach-flushing. Stomach-flushing is described in detail. We believe it has certain advantages over other methods; it samples food from the upper parts of the gut before most digestion has occurred and incurs very low […]
Analysis of the measurements of museum specimens of Mangrove Honeyeaters Lichenostomus fasciogularis indicated that there were significant differences between the sexes. Males had larger wing, tail and culmen lengths and weights than females. Most of these parameters were not normally distributed but Critical Values were calculated to allow sexing of individuals with approximate levels of […]
