One hundred and ninety two (192) islands, islets and rocks were surveyed over 21 days in December 2006. Seabird nesting habitat was mapped in its entirety […]

FORAGING OF WHITE-BELLIED SEA-EAGLES Haliaeetus leucogaster IN RELATION TO MARINE FISH FARMS IN TASMANIA
Posted: 10/04/2021The ranging and foraging behaviour of adult male White-bellied Sea-Eagles Haliaeetus leucogaster, at three marine fish farms and three non-aquaculture sites, were studied in the breeding season (August–December 2000) by radiotelemetry. At non-aquaculture sites (Sea-Eagle nests >8 km from fish farms), areas of Sea-Eagle home ranges averaged 77.2 square kilometres (minimum convex polygon) and 92.2 […]

Posted: 10/04/2021The Tasmanian Department of Primary Industries and Water maintains a database of raptor nests through its Natural Values Atlas for the purpose of nest-site management (the Tasmanian Raptor Nest Database). During late spring 2003, 79 of the 237 White-bellied Sea-Eagle Haliaeetus leucogaster nests then listed in the database were surveyed. Three nests were found to […]
Read MoreMODELLING THE NESTING HABITAT OF THE WHITE-BELLIED SEA-EAGLE Haliaeetus leucogaster IN TASMANIA
Posted: 10/04/2021The nesting habitat of the White-bellied Sea-Eagle Haliaeetus leucogaster was assessed and modelled in a region of south-eastern Tasmania. The selected habitat was assessed by comparing the habitat parameters of 28 nest sites with those of the entire study area. The activity status of nests during the 1997–98 breeding season, and some variables, were measured […]

Posted: 10/04/2021TIME PARTITIONING AND SUBSTRATE USE OF RED-BACKED FAIRY-WRENS Malurus melanocephalus
Posted: 10/04/2021Red-backed Fairy-wrens Malurus melanocephalus are small insectivorous birds that inhabit Australia’s tropical and subtropical savannas. We studied a colour-banded population in the Kimberley, Western Australia, to describe how they partition their time among the main habitat elements within their savanna environment. Eighty-nine focal watches on 29 individuals showed that Red-backed Fairy-wrens spend most of the […]
