SUMMARY
Loyn, R. H. 1978. A survey of birds in Westernport Bay, Victoria, 1973–74. Emu 78: 11–19.
A survey of birds in intertidal areas of Westernport Bay was begun in October 1973 and is continuing. This paper describes results of the first year's fieldwork. A monthly census at high-tide roosts was carried out with the help of the Bird Observers' Club and other voluntary observers. In this year the Bay supported a population of about 17,000 waders and 18,400 other shore birds. Some species were commoner in Westernport Bay than in other parts of Victoria: Eastern Curlew, Whimbrel, Bar-tailed Godwit, Greenshank, Grey-tailed Tattler and Terek Sandpiper. The distribution of mangroves and time of exposure of mudflats appear to be important factors involved in determining distribution and abundance of birds.
