...S. V. Briggs; S. A. Thornton This study investigated relationships between durations of inundation in River Red Gum wetlands and waterbird breeding, in particular the durations of flooding under nest trees that waterbirds need to breed successfully; and developed guidelines for managing water...

...Adam Smith At the time of European settlement, the wetlands of the Clarence River floodplain sustained considerably higher numbers of waterbirds than at present. These wetlands were valuable natural resources for the local Aboriginal people with ducks, geese and swans easily hunted using...

Overall waterbird abundance and diversity was low due to flood conditions and local rainfall providing ample feeding and nesting areas, thus spreading...

... of take-off distances on animal responses, which consistently showed that greater take-off distances resulted in less disturbance during take-off. These findings were mainly limited to studies of waterbirds, aquatic birds and pinnipeds. However, one study on Red-winged Blackbirds found that launching...

... bird species were detected on sites during our study, 125 being considered landbird species and 13 being waterbirds. A further 42 species were detected outside the spatial or temporal boundaries of the timed 10 minute site counts, 17 of which were waterbirds that were seen at adjacent dams...

... and harbour a great variety of plants and waterbirds. However, there has been a recent shift from the traditional sheep and cattle grazing land use in this area to agriculture and a con- sequent need to monitor the affects of this change on the native flora and fauna.

These reasons are partly why the concept of flyway , a geographic area used to encompass the entire range of migratory waterbird species, was proposed, to (i) represent the complexities of migration in a simple and inclusive geography, (ii...
