Mudjimba Island has recently been included in the Maroochy River Conservation Park. One of the factors
influencing the decision was that the island's Wedge-tailed Shearwater
Puffinus pacificus colony may be the only
viable colony remaining in south-east Queensland and one of only two colonies that inhabit mainland islands in
Queensland. The colony was first described by Lane and Battam (1984, 1985) after they visited the island in
February 1984. They estimated a breeding population of between 1 500 and 2 000 breeding pairs. This paper
presents an estimate of approximately 2 700 burrows for the 1997/98 season; breeding rates of approximately
37 per cent for the 1996/97 and 1997/98 seasons; and a breeding success rate of about 84 per cent at fledgling
stage for the 1997/98 season.
