Using sexual dimorphism in morphometric traits to sex Eastern Yellow Robins Eopsaltria australis

Posted: 04/04/2017
Category: Corella
Author(s): Jonathan T. Coleman and Penn Lloyd

The identification of the sex of individuals is important for the investigation of gender roles in the behavioural ecology of species and sex-specific differences in demography. We investigated the extent of sexual size dimorphism in the Eastern Yellow Robin (Eopsaltria australis), a species with no sex differences in plumage, and the utility of morphometric traits […]

Methods for field recognition of individual Australian Pelicans Pelecanus conspicillatus from eggs to adulthood

Posted: 18/02/2017
Category: Corella
Author(s): Gregory R. Johnston

Recognition of individual animals is crucial to being able to answer many pure and applied research questions in zoology. Marking members of species that undergo large changes in size during development can be particularly challenging. This paper describes successful methods used to mark Australian Pelicans Pelecanus conspicillatus, which show mass changes of over two orders […]

Mangrove Gerygones Gerygone levigaster are short-lived compared to other small Australian passerines

Posted: 18/02/2017
Category: Corella
Author(s): Jonathan T. Coleman and Richard A. Noske

South temperate Australian passerines are generally long-lived compared to birds of the north temperate region. However, few data are available on the survivorship of tropical and sub-tropical Australian birds. We examined survival in the Mangrove Gerygone Gerygone laevigaster at a sub-tropical location in Brisbane, south-east Queensland. Based on a dataset of 414 Mangrove Gerygones banded […]

Do exotic birds dominate feeding at garden food stations in Melbourne in winter?

Posted: 25/11/2016
Author(s): Chanaka Ruwandeniya and Alan Lill

Deliberate feeding of wild birds is common in urban Australia and supposedly has both costs and benefits for the birds and the humans that feed them. If urban domestic garden food stations are dominated by common exotic species, they may ultimately not promote, or even reduce, urban native bird species diversity. However, too few investigations […]

Nestling and post-fledging growth and development in an Australian passerine: Hall’s Babbler Pomatostomus halli

Posted: 25/11/2016
Author(s): Dean J. Portelli

Postnatal growth and development has rarely been studied in passerines of the southern hemisphere, particularly Australian species. Developmental changes in external morphology and the growth in body mass and size of nestling and juvenile Hall’s Babblers (Pomatostomus halli) were quantified and described. Additionally, a guide to ageing nestlings to the nearest day was developed to […]
