Ardea purpurea
Drawn from open occurrence records in and around Yala 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, May, June, July, August, September, 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: 2 squares of 25 km carry records for Purple Heron in and around Yala National Park, and the 3,223 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.
Garden Route, Table Mountain and Kruger National Park are among the four atlas places where the Purple Heron is recorded, with records concentrating in India, Spain, France, South Africa and Taiwan. The atlas holds about 336,000 open records of this bird from 36 countries. Because the map shows where these records concentrate, it represents a portion of the total range.
Of the 15 species with an atlas page recorded in and around Yala National Park, the Purple Heron is the 2nd most recorded.
