Abstract

The diet of the Beach Stone-curlew Esacus magnirostris was examined by analysing 242 scat samples collected from four sites in northern New South Wales. All samples included remains of crabs, with some also containing fragments of insects and molluscs. Nine species of crab were identified. The Light Blue Soldier Crab Mictyris longicarpus was the most frequently recorded prey item (present in >80% of scats) at the Wooli and Nambucca Rivers, but the Dark Blue Soldier Crab M. platycheles was most frequently recorded (73% of scats) at the Corindi River. Seven of these crab species have not been described previously in the diet of the Stone-curlew. The diversity of crabs identified in scats indicates that Stone-curlews forage in a variety of habitat types.
