Included here are nesting range maps for those species which normally nest in the state, and the approximate location(s) where migrants, winter visitants, casual and accidental species occur or have occured.

For regularly occuring species which are strictly migrants, summer visitors or winter visitors, the maps attempt to depict those areas where these species are most often or most likely to be found. Not every record is depicted for migrants, as they can often occur anywhere. In those cases where migrants usually occur in a very restricted area, (e.g., Parasitic Jaeger, Red Knot), only those locations are shown, even though records from other areas may have been recorded.

These maps are only intended to be used as a general guide. Obviously, without accompanying text to put species maps in their proper context, the real status of any bird depicted cannot be very accurate. Details such as abundance, frequency or records outside the normal range or season of regularly occuring species are not shown.

While we have made every effort to depict accurate information, variations in actual ranges from year to year are inevitable. For a more complete discussion, refer to Robert Janssen's Birds in Minnesota.
