Seabirds around fishing vessels

White-chinned petrel

Procellaria aequinoctialis

The white-chinned petrel breeds in burrows on islands around the subantarctic region. The species' main breeding area is in South Georgia. However, around 200,000 pairs are estimated to breed in New Zealand, mainly on Disappointment and Antipodes Islands. This species is difficult to distinguish at sea from the black petrel and the Westland petrel, and misidentifications can be expected.

Mean number of white-chinned petrel recorded around fishing vessels during counts carried out by government observers, binned to 0.4 degree of longitude and latitude. The size of the circle indicates the number of observations, whereas the colour indicates the mean number of birds recorded during counts. Empty circles indicate that no birds were observed. The grey areas indicate water depths of less than 1000 m.
