In order to breed, waterbirds require appropriate sites for their nests. Most nests of waterbirds (families Pelecaniformes, Ciconiiformes) in River Red Gum wetlands were in clumps of live, mature trees next to open water. Often these Red Gums had branches leaning over the water. Retention of these nest trees is essential for waterbird conservation. The […]

Pied Currawong abundance was surveyed in 1988, 1989 and 1990 in Armidale, New South Wales. Pied Currawongs congregated each April and dispersed in the following September. This pattern is consistent with other studies in south eastern Australia and is best explained in terms of a combination of dietary shifts and breeding pressure. The seed dispersal […]

Author(s): Kenneth Er, Andrew Robinson and Christopher Tidemann

The fixed-width strip transect method is increasingly becoming an important bird sampling technique in Australia. In this survey, different sampling durations and strip widths were evaluated for the sampling of birds in Yellow Box woodland remnants in the ACT. The survey showed that the choice of sampling duration and strip width had a significant effect […]
