Tips for Birding in Illinois

1

Check tide tables before visiting coastal locations in Illinois — low tide exposes mudflats that attract the most shorebirds and waders.

2

Bring waterproof boots and insect repellent when visiting Illinois's wetland areas — trails can be muddy and mosquitoes are active in warmer months.

3

Learn bird songs before exploring Illinois's forested areas — many woodland species are heard long before they are seen, especially warblers in the canopy.

4

Plan visits during peak migration (mid-April through May and September through October) for maximum species diversity in Illinois.

5

A spotting scope is essential at Illinois's lakes and reservoirs — many waterbirds stay far from shore and are difficult to identify with binoculars alone.
