Vanellus chilensis
Drawn from open occurrence records in and around Iguazú 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 Southern Lapwing in and around Iguazú National Park, and the 13,539 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.
The Osa Peninsula and Corcovado are the two atlas places where the Southern Lapwing is recorded. Its records concentrate in Chile, Argentina, Brazil, Colombia and Panama, and the atlas map follows where they gather most thickly. There are about 534,000 open records of this bird from 14 countries.
Of the 55 species with an atlas page recorded in and around Iguazú National Park, the Southern Lapwing is the 3rd most recorded.
