Volatinia jacarina
Drawn from open occurrence records in and around Chapada dos Guimarães 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 Blue-black Grassquit in and around Chapada dos Guimarães National Park, and the 1,428 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, Corcovado and Arenal are among the four atlas places where the Blue-black Grassquit is recorded, with records concentrated in Costa Rica, Colombia, Belize, Panama and Brazil. The atlas holds about 250,000 open records for this bird from 17 countries, and the map follows where these records gather.
Of the 35 species with an atlas page recorded in and around Chapada dos Guimarães National Park, the Blue-black Grassquit is the 9th most recorded.
