Spring Migration in Indiana: Where, When, and What to Look For

Indiana sits squarely on the Mississippi Flyway, which means hundreds of millions of birds funnel through the state every spring. The peak window is roughly April 25 through May 15, with neotropical warblers leading the show. Here’s what to expect, when, and where.

Late March: Waterfowl and early arrivals

The first wave is dabbling ducks and Sandhill Cranes. Goose Pond Fish & Wildlife Areain Greene County is the marquee hotspot — thousands of cranes stage there in late February and into March, and Northern Pintail, Green-winged Teal, American Wigeon, and Northern Shoveler come through in big numbers. Eagle Creek Reservoir in Indianapolis is a reliable closer-to-home alternative.

Early-to-mid April: Sparrows, shorebirds, the first warblers

Henslow’s Sparrows arrive on grassland reclaimed mine land. Pectoral and Solitary Sandpipers begin showing up at flooded fields. The first warblers — Pine, Yellow-rumped, Palm, Louisiana Waterthrush — arrive in deciduous forest. Eagle Creek Park, Holliday Park, and the Tippecanoe River State Park oak forests are productive.

April 25 through May 5: The big push

Peak warbler week. On a good morning at Eagle Creek Park’s North Beach woods, fifteen to twenty warbler species are realistic: Black-throated Green, Black-throated Blue, Magnolia, Chestnut-sided, Cape May, Bay-breasted, Blackburnian, Tennessee, Nashville, Northern Parula, American Redstart, and an assortment of Empidonax flycatchers, vireos, and thrushes. Use Birder AI’s sound ID liberally — warblers don’t sit still and the songs are diagnostic when learned.

May 6 through May 15: The cleanup

Late warblers (Mourning, Connecticut, Wilson’s, Canada), late thrushes (Gray-cheeked, Bicknell’s on rare occasions), and the last Empidonax flycatchers come through. Shorebird passage continues at Goose Pond, with Stilt Sandpiper, Wilson’s Phalarope, and (in good years) White-rumped Sandpiper.

Tactics for a good morning

• Be on-site by 6:30am. Songbirds are most active in the first two hours after sunrise. By 10am, the show is usually over.
• Listen first, look second.You’ll hear ten warblers for every one you see. Birder AI’s sound ID can tag what’s singing while you scan visually.
• Move slow. A mile in two hours is a fast morning of birding. Stop every fifty yards and listen for thirty seconds.
• Check the weather. South winds at night dump migrants in the morning. North winds clear them out. BirdCast gives nightly migration intensity forecasts.
