Abstract

[Extract] The Golden-shouldered Parrot Psephotus chrysopterygiusis listed as an Endangered species under Schedule 2 of the Queensland Nature Conservation (Wildlife) Regulation 1994, and the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). The species fits the criteria of endangered under IUCN Red List categories (IUCN SSC 2001): Category B1a,b(i)(ii)(iii)(iv) (extent of occurrence <5000 sq.km, occurs at fewer than five locations, continuing projected decline in extent of occurrence, area of occupancy, quality of habitat, number of mature individuals; (Garnett & Crowley 2000)). It is listed under Appendix I of Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) (Garnett & Crowley 2002). The species occurs only on Cape York Peninsula in two areas totalling less than 2000 km2area of occupancy and ranging over less than 3,000 km2 extent of occurrence. The northern population is centred around Morehead River in an area of around 1,380 km2, and the southern one around the Staaten River in an area of around 400 km2(Fig 1). The population of adults is in the order of 2,000 to 2,300 birds, increasing possibly to 3,600 adult and juvenile birds after the breeding season and declining back to the core population during the later dry season and wet season each year. Due to limited surveys and data, it is not clear whether or not the population is increasing, stable or declining. A Recovery Plan for the golden-shouldered parrot Psephotus chrysopterygius2003-2007 (Garnett & Crowley 2002) was prepared in 2002 and included a number of objectives. This report responds to: Specific Objective 3: Determine population trends. A Prospectus for the study, 'Re-assessment of the status of the Golden-shouldered Parrot Psephotus chrysopterygius', prepared for the Caring for Our Country grants provided the scope of the study (Appendix 1). Anticipated outcomes of the study were expected to be: A report documenting trends in the Morehead population of Golden-shouldered Parrots enabling a comparison to be made with population estimates in 1996 and 2001 and a reassessment of conservation status. GPS locations of all located nest sites for the 2009 breeding season. The work undertaken complies with this scope, and is described below. The contract (CY TBIO 01) for the study included two milestones: •A nest survey of the Morehead population during the late breeding season between March and May 2009 to ascertain whether the apparent reversal in the decline of the Morehead population has been maintained; •Observations of predation and nest damage, of flock sizes, sex ratios, number of juveniles together with presence/absence of Pied Butcherbirds and/or Black-faced Wood swallows. The survey was urgent as the previous survey was conducted about 8 years ago (2001) and should have been conducted within 5 years of the previous one. This project was funded by the Federal Government's Caring for Our Country program, and managed by the Queensland Government Dept of Environment & Natural Resource Management.
