RECOVERY OUTLINE Hooded Plover (eastern) 1 Family Charadriidae 2 Scientific name Thinornis rubricollis rubricollis (Gmelin, 1789) 3 Common name Hooded Plover (eastern) 4 Conservation status Vulnerable: C2b 5 Reasons for listing 9 Ecology The population of this subspecies contains fewer than Hooded Plovers live on ocean beaches, particularly 10,000 individuals, and is likely to be decreasing. It is wide beaches with large amounts of beach-washed sufficiently mobile to be considered one sub- seaweed, and creek mouths or inlet entrances with population (Vulnerable: C2b). large flat areas of sand and some storm wrack (Schulz, 1988). They also use nearby reef platforms, coastal Estimate Reliability inlets and lakes. They forage in the shore-wash zone, 2 Extent of occurrence 1,500,000 km high taking polychaetes, molluscs, turions, crustaceans and trend stable high seeds (Marchant and Higgins, 1993). They lay 2-3 eggs Area of occupancy 4,000 km2 medium on the upper levels of the beach, in adjacent sand trend stable medium dunes (Marchant and Higgins, 1993), or, less often, on No. of breeding birds 3,000 medium rocky headlands (G. Backhouse). trend decreasing medium No. of sub-populations 1 medium Generation time 5 years low 6 Infraspecific taxa T. r. tregellasi from south-west W. A., a taxon re- established by M. A. Weston (unpublished) on the basis of morphology and plumage (D. Rogers in Marchant and Higgins, 1993), is Near Threatened, as is species as a whole. Genetic samples are to be analysed to verify taxonomy. 7 Past range and abundance Found along coasts of south-east Australia from Wide Bay, south-east Queensland to Fowlers Bay, 10 Threats S.

Birds around human settlements are increasingly since 1940s (Morris, 1989, Cameron and Weston, subject to predation by artificially high numbers of 1999, NSW NPWS, 2000). Otherwise distribution as Silver Gulls Larus novaehollandiae (T. Dennis) and above. Regional estimates: Tasmania, 1,700 individuals ravens Corvus spp. (P. Park, M. Weston). Predators are (Newman and Patterson, 1984, Holdsworth and Park, more likely to be successful where there is also human 1993), including 815 birds counted along 391 km in disturbance, and humans often accidentally crush eggs 1996/7 (Woehler and Park, 1997); Victoria, at least or young (Schulz and Bamford, 1987, Buick and 470 and probably as many as 600 birds (Murlis, 1989, Paton, 1989, Hanisch, 1998, Dowling and Weston, Weston, 1995); New South Wales, about 50 birds 1999). At Mornington, before controls were (Morris, 1989), South Australia, 540 birds, including up introduced, over 30% of nests were trampled by dogs to 200 birds in the south-east (Natt and Weston, or people (Dowling and Weston, 1999).
