Background.
The conservation status of the Grey-crowned Babbler Pomatostamos temporalis is near threatened being extinct in S.A. and A.C.T. endangered in Vic. and declining in N.S.W. (Garnett & Crowley 2000). This project will investigate the relationship of habitat types and land use to the presence or absence of Grey-crowned Babblers at two study sites in north-east New South Wales and it will also investigate their group formation and movements. This information would be useful for conservation and land management. There is little published data on measurements of Grey-crowned Babblers and this project will provide morphometric data which could be useful for sexing. The project will also examine the movements, and species abundance of bird assemblages at the two site
Project Aims.
Determine the effect of two different types of land management, in the same forest type, on Grey-crowned Babbler populations.
Identify family groups of Grey-crowned Babblers at two study sites within the study area and determine if there is any movement of individuals between groups.
Determine territory size of Grey-crowned Babblers at the two study sites.
Determine the seasonal changes in abundance of nectarivorous and insectivorous bird populations at the two study sites and provide morphometric data for these birds.
Determine the seasonal site fidelity of nomadic and migratory birds at the two study sites.
