Body weights and dimensions were recorded for 70 fledglings at Heron Island, on the southern Great Barrier Reef. Results show that the length of the longest primary feather and tarsus were significantly different between habitats, with the Fringe showing highest and Buildings area showing lowest means. This outcome probably resulted from most nestlings measured in […]

Morphological measurements were made from 233 wild Wedge-tailed Eagles Aquila audax on the Nullarbor Plain, 116 museum specimens from southern Australia and 30 dead birds from New South Wales. In the birds from the Nullarbor Plain, reversed sexual size dimorphism (female larger than male) was found in all characters examined. Among the museum specimens (a) […]

Bird species richness and abundance were recorded along 28 fixed-width strip transects located within 10 study sites dominated by Yellow Box Eucalyptus melliodora and Blakely’s Red Gum E. blakelyi. This was conducted across four seasons in 1994. This paper reports the seasonal variation in bird species composition and abundance observed in these study sites. The […]
