Silver Gull populations have increased substantially in the past 50 years. This is primarily because they are scavengers and have been able to utilize human refuse.

The density of nesting burrows of the Wedge-tailed Shearwater Puffinus pacificus was measured in 224 quadrats on Heron island, Great Barrier Reef. Field measurements of the unconfined compressive strength of the soil material were made for each quadrat. Lowest burrow densities occurred in quadrats at both upper and lower ends of the soil strength range, […]

Assessment by routine morphometric analysis found no geographic variation in the Regent Honey-eater Xanthomyza phrygia but distinguished significant sexual dimorphism in size, intensity of plumage colour and extent of warty skin on the face. Seasonal distribution of records indicates that coastal south-eastern Australia forms part of the core breeding range of the species.

Comparisons between the ecology of Flame and Scarlet Robins at a sympatric breeding site suggested that Flame Robins migrated during the winter months because of a decline in the availability of their major prey. During the nine months that Flame Robins were present at the breeding site, they foraged for flying insects twice as often […]
