Procellaria parkinsoni Black Petrel Gray 1862
Family: Diomedeidae

Taxonomy

Procellaria parkinsoni Gray 1862 is accepted nomenclature for the Black Petrel. Originally Procellaria parkinsoni Gray 1862. The Black Petrel has previously been considered polytypic with Procellaria westlandica. (Westland Petrel) until Jackson (1958) proposed recognition at the specific level based on demographic differences, a view also supported by morphological and genetic differences (Marchant & Higgins 1990, Nunn & Stanley 1998). ACAP has concluded on advice from its Taxonomy Working Group that available data warrant recognition of the Black Petrel at the specific level with the nomenclature widely accepted (Brooke et al. 2008, ACAP 2012e).

Endemic to New Zealand with two breeding sites on Great Barrier Island, and Little Barrier Island (ACAP 2012e). The Black Petrel is an annual breeder when successful (Imber 1987). Adults arrive at colonies from October with females laying a single egg from mid-November to late
