Ontario Breeding Bird Atlas

Yellow warbler © Ken Janes

The Atlas of the Breeding Birds of Ontario is your comprehensive guide to everything about breeding birds in the province.

The Ontario breeding bird atlas contains more than 700 full colour pages of photographs, maps, and charts for the 300 species that breed in Ontario. Profits from the sale of atlases go towards bird conservation projects in the province. Order your copy now for just $63.

The Atlas of the Breeding Birds of Ontario is a collaborative undertaking of Ontario Nature,  Bird Studies Canada, Canadian Wildlife Service, Ontario Field Ornithologists, and the Ontario Ministry of Natural Resources. It is a volunteer-based effort that used a rigorous scientific approach to determine the distribution and populations of bird species breeding in Ontario, and how those numbers have changed since the 1980s.

  • More than 3,000 volunteers logged over 150,000 hours of field work during the development of the atlas.
  • Volunteers submitted 1.2 million individual breeding bird records.
  • 286 species were reported with breeding evidence in the province from 2001–2005.
  • Breeding records were submitted for more than 4,800 10-kilometre squares: covering areas of the province from Hudson Bay to Pelee Island.
  • Over 68,000 point count surveys (which quantify species abundance) were conducted and will be used to produce the first province-wide maps of the relative abundance of many species.
  • Over 18,000 forms were submitted for rare or colonial species.

Atlas data is a critical resource for scientists and conservation and can be used to inform recovery plans for species at risk, environmental assessments, and land use planning. The atlas is an invaluable reference for both environment and resource managers and birders alike.


The atlas is a monumental achievement. Not only is it a stirring example of co-operative research but the detailed results have been presented with a remarkable clarity and style.

Invaluable for the thoroughness of its science, the Atlas is also a wonderful book to simply browse. The species accounts are clean, jargon-free, and inviting; the graphics contain a wealth of visual information; and the text is profusely illustrated with photographs of the birds. This book is a must for everyone interested in birds, Ontario, and the natural world.
