What does Illinois’s count include?

  • Regular species and rare visitors alike.
  • Extinct species, and species no longer found in Illinois.
  • Not counted: one scrub-jay accepted as either a California or a Woodhouse's Scrub-Jay, without saying which.

Why might you see a different number?

A state’s count is every species ever accepted on its official list, so a figure from another year, or one that counts something else, won’t match.

Every state’s list follows its own rules: see why the counts differ from state to state.

How do you count your own Illinois list?

Your state list is every species you’ve seen in the state. If you log your sightings in eBird, it lets you filter your life list by place, a state included (eBird’s My eBird help page, updated March 28, 2025), and the data download you can ask for gives the state of every sighting: our guide shows how to download your own eBird data. On paper, count the species you’ve seen in Illinois; what is a life list? explains how birders keep their lists.

If you’d like your whole life list in print, Birdfolio turns it into a hardcover book, each species beside a classic painting.

Northern Cardinal

Illinois’s state bird is the Northern Cardinal, the state bird since 1929. Chosen by a vote of Illinois schoolchildren.

Audubon painted it too: plate 159 of The Birds of America.
