The article discusses a study on the historic distribution of the Grey Grasswren Amytornis barbatus barbatus in New South Wales (NSW). The study procedure included bird capture using mist nets. The Grey Grasswreb was first reported on July 7, 1967 by researchers N. J. Favaloro and W. Adams. This subspecies was described as vulnerable in accordance with the NSW Threatened Species Conservation Act of 1995. Options for habitat protection and future management of the Grey Grasswren are also presented.

The article discusses a study that documented and monitored the avian faunas in the north-western section of remnant Cumberland Plain woodland communities at Agnes Banks Nature Reserve in New South Wales. Findings show an increase in nectarivorous species from 47 percent of all birds captured in the first period to 58 percent in the second period. Insectivorous species decreased from 44 to 41 percent.

Our objective was to determine the levels of selected airborne contaminants in ambient air at the Mississippi Sandhill Crane National Wildlife Refuge, Mississippi, that might be affecting the health of endangered cranes living there. Two high-volume air samplers were operated at separate locations on the Refuge during May-September 1991. The sampling media were micro-quartz filters in combination with polyurethane foam plugs. Composite bimonthly samples from each station were analyzed for polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), coplanar polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs). Overall, residue concentrations were low. The toxic PCDD isomer 2,3,7,8-tetra-CDD was not detected, nor was penta-CDD. There was no difference (P>0.05) in residue concentrations between stations or over time and meteorological parameters were not correlated with residue concentrations. Because contaminant levels and patterns may differ seasonally, we recommend that air samples collected during winter months also be analyzed for these same chemical groups.
