Since 1972, 807 Peregrine Falcon chicks have been banded in Victoria and 66 of these have been either recovered or resighted. There was a slight but significant (P < 0.05) female-bias in the sex ratios of both the nestlings banded and the subsequent band recoveries. Most (69.7%) recoveries were made more than 4 km from […]
Socially monogamous Magpie-larks Grallina cyanoleuca were studied to evaluate whether the potential for sperm competition was reduced by mate guarding or frequent copulation with the mate. Breeding among nearby pairs was sufficiently asynchronous to generate opportunities for extra-pair copulations, but frequent intra-pair copulation was not evident. The mean intra-pair and pair-to-nest distances were significantly smaller […]
The post-juvenile moult strategies of three coexisting woodland finch species in monsoonal northern Australia were compared. Juvenile Gouldian Finches tended to moult at the same time of year as each other regardless of age, whereas in juvenile Long-tailed and Masked Finches the commencement of moult was progressive through the year and may be related more […]
