Polioptila plumbea
Drawn from open occurrence records in and around Machalilla 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 Tropical Gnatcatcher in and around Machalilla National Park, and the 3,146 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.
Osa Peninsula, Corcovado and Arenal are among the six atlas places where the Tropical Gnatcatcher is recorded, with records gathering most thickly in Costa Rica, Panama, Colombia, Venezuela and Ecuador. The atlas holds about 140,000 open records of this bird from 15 countries, and the map follows where they concentrate. Because it is recorded in both hemispheres, seasons differ by region and each place page shows the months recorded there.
Of the 51 species with an atlas page recorded in and around Machalilla National Park, the Tropical Gnatcatcher is the 3rd most recorded.
