Egretta caerulea
Drawn from open occurrence records in and around Everglades 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: 7 squares of 25 km carry records for Little Blue Heron in and around Everglades National Park, and the 32,026 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, Tortuguero and Arenal are among the five atlas places where the Little Blue Heron is recorded. Records of Egretta caerulea concentrate most heavily in the United States, Costa Rica, Mexico, Belize and Panama. This atlas holds about 1.3 million records from 12 countries, and the map follows where these records concentrate.
Of the 38 species with an atlas page recorded in and around Everglades National Park, the Little Blue Heron is the 3rd most recorded.
