The following pages contain lists, of nearly all the bird species recorded within the Fermilab site boundaries. The names and ordering follow that of the American Ornithologists Union's check-list of North American birds. The lists also indicate at what time of year each species was found. To do this we have divided each year into 48 quarter-months and split the entire survey into five year periods. The first period started in 1987. A symbol is entered into the table for each record, indicating in which survey periods the record occurred. A legend describing these symbols is included with each page. Each list entry also contains a link to some text describing the bird's status on the site. Some exotic species have been excluded from the main list since they are extremely unlikely to have occurred naturally.
