Breeding bird atlases are a collection of maps used to indicate the presence of bird species, usually over a 5 year period. The maps are usually broken into small gridded areas, e. g. 10 kilometre squares, and birding volunteers populate the squares with data that reflect their observations on the presence of specific bird species. A large number of U. S. states and Canadian provinces have their own breeding bird atlas. Outside of North America they are less popular.Most of the atlases listed here have simple maps with points or grid squares indicating the presence of species. Only the Australian site lists some sort of interactive map, albeit limited. Other breeding bird atlases have websites but only the only listed actually have web-accessible maps. A number of atlases are in the process of being updated or created.
