Seabirds are the world’s most threatened group of birds, primarily a result of deadly encounters ‘at sea’ with fisheries and ‘on land’ with invasive pest mammals. Additionally, the struggles to find available, suitable habitats compound the threat faced by seabirds.
The Auckland region is renowned as a seabird hotspot, with 27 breeding species in the greater Hauraki Gulf in particular. Most of these are ‘threatened’ or ‘at risk’ of extinction. Auckland Council, through provisions in the Auckland Plan and Indigenous Biodiversity Strategy, is implementing seabird management practices to improve their regional conservation status. Critical steps to implementing these practices are to establish a stocktake of where seabirds are in the region, an understanding of what their breeding success is, and what threats exist at breeding sites.
This report details the first comprehensive survey of grey-faced petrel, or ōi, Pterodroma macroptera gouldi (GFP) and little penguin, or kororā, Eudyptula minor iredalei (LP) on Auckland’s west coast, the seabirds which are most likely to be breeding over the winter on Auckland’s mainland. The survey was undertaken on the Constable Road local parkland (also known as the Muriwai Marginal Strip) and surrounding areas between Muriwai Beach and Te Henga (Bethells Beach). This area was chosen because of specific interest by Auckland Council’s Biodiversity group to identify biodiversity values in this area to help identify and prioritise management actions, and also as there have been anecdotal observations of GFP and LP in this area.
