Distribution and habitat of Australian Pied Oystercatchers Haematopus longirostris along the SE Australian coast
Abstract
Australian Pied Oystercatchers Haematopus longirostris and their habitat were surveyed on 72 beaches and 674 km of coastline, from Fraser Island, Queensland to near the New South Wales-Victoria state border, in 2015-2018. A grand total of 232 individual birds (the sum of mean beach counts) and 41 oystercatcher territories were counted. Regression models for mean oystercatcher count density indicated a positive response to the abundance of the surf clam Donax deltoides, a positive New South Wales Far North Coast regional effect and a negative response to the proportion of urban beach. Models for oystercatcher territory density indicated a positive Far North Coast effect and a negative response to pedestrian access density. This report upgrades the coastal development and human recreation disturbance threats for the species.
