Tringa stagnatilis
Drawn from open occurrence records in and around Blue Mountains 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, September, October, November and December, with the widest coverage in January, February, 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: 1 square of 25 km carry records for Marsh Sandpiper in and around Blue Mountains National Park, and the 224 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.
