Ardenna grisea
Drawn from open occurrence records in and around Fiordland National Park, aggregated onto a 25 km grid. A cell is matched by its centre, which can sit up to 16 km outside the boundary, so this covers the surrounding country too.
Occurrence records measure where people looked and found something, which is not the same as where the animal is. This is a relative likelihood, not a probability.
Records exist for January, February, March, April, October, November and December, with the widest coverage in January, February, March, April, October, November and December. A quiet month can mean the animal was absent, or that nobody was looking.
A grid cell is a square of the map, not a sighting: 1 square of 25 km carry records for Sooty Shearwater in and around Fiordland National Park, and the 551 records behind them were collected by other people and published openly. Nothing here counts animals, and a place with more records is not always a place with more animals.
Table Mountain National Park is the atlas place where the Sooty Shearwater is recorded, with records gathering most thickly in the United States, Mexico, New Zealand, Chile and Canada. The atlas holds about 225,000 open records of this bird from 21 countries, and the map follows where they concentrate. Because it is recorded in both hemispheres, the months of recording differ by region. Each place page shows the months recorded there.
Of the 3 species with an atlas page recorded in and around Fiordland National Park, the Sooty Shearwater is the 2nd most recorded.
