Anas undulata
Drawn from open occurrence records in and around Aberdare 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: 3 squares of 25 km carry records for Yellow-billed Duck in and around Aberdare National Park, and the 1,890 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.
In Addo Elephant National Park, uKhahlamba-Drakensberg Park and Garden Route National Park, the Yellow-billed Duck is recorded among 14 atlas places. Its records concentrate in South Africa, Kenya, Uganda, Lesotho and Rwanda. The atlas holds about 200,000 records of the species across six countries, and this map follows where they gather most thickly.
Of the 72 species with an atlas page recorded in and around Aberdare National Park, the Yellow-billed Duck is the 10th most recorded.
