Of the more than 30 species of marine mammal occurring within the Great Barrier Reef Marine Park (GBRMP), three are the focus of wildlife-based tours: humpback whales (Megaptera novaeangliae), dwarf minke whales (Balaenoptera acutorostrata) and dugongs (Dugong dugon). Currently (April 2001), 19 permits, comprising 31 ships and two aircraft, allow whalewatching in the GBRMP. The combined passenger capacity of these craft is 3,238 at any one time (e.g., per day). However, fewer than 15,000 persons were recorded in ?dedicated? whalewatching tours each month during the May - October ?whale-watching? season between 1998 and 2000. Watching M. novaeangliae occurs primarily in the Central and Cairns Sections of the GBRMP, with most activity focused in the Whitsundays. Permitted levels of whale-watching are capped at eight permits in the Cairns Area, and at 11 permits in the Whitsundays. Other tours include: a specialised form of whale-watching involving swimming with B. acutorostrata which ...

The attraction of lighthouses to night-flying birds is a well known phenomenon and there are many reports of casualties in collisions with them (Lockley, 1973; Durham, 1976; Avise and Crawford, 1981; Verheijen, 1981).

Brief observations of forty-six landbirds of New Caledonia were made during a one-month search for the Wood Rail Tricholimnas lafresnayanus in December 1976. The effects of current policies on the island are probably endangering some endemic species.

The birds of the Cocos (Keeling) Islands, Indian Ocean, were surveyed by T.S. and W.S. in January 1982 and other records by W.S. and K.D. are included. Thirty-four species are recorded, of which nine are new records for the islands. Three species, introduced between 1885-1906 and recorded in 1940-41 or 1958, are believed to be extinct. Very few land or sea birds remain on the main atoll and the large rookery of seabirds on North Keeling Island is threatened by a recent increase in the number of birds killed. The endemic subspecies of the Buff-banded Rail Rallus philippensis andraosi which is common on North Keeling Island but rare on the main atoll, appears to be endangered.
