Screen tonight’s setup
Wind direction and precipitation tell us whether a region has supportive movement, holding, or possible grounding conditions.
Tonight’s movement setup → tomorrow morning’s best places → what Michigan birders are actually reporting. Built for both spring and fall migration.
Combining regional NWS wind/precipitation signals with recent eBird reporting. BirdCast remains the radar confirmation layer.
Use the layers in this order. That keeps weather context, real observations, and radar evidence from being confused with one another.
Wind direction and precipitation tell us whether a region has supportive movement, holding, or possible grounding conditions.
Recent county observations tell us whether birds are already being found near the places you might drive to at dawn.
Open BirdCast for radar evidence, then the county/species pages for the latest local reports and exact birds.
Six focal migration corridors. No mystery score: every recommendation shows the weather signal and recent reporting behind it.
These are broad seasonal groups, not a claim that a particular species migrated last night. Use the live sightings below for what has actually been reported.
Recent statewide notable eBird observations. Tap a species to open its Michigan profile and current sighting map.
Wind and precipitation are a movement setup signal. They do not prove birds flew over a region.
Recent observations show what people have actually reported on the ground. Reporting effort varies by place and day.
Use the official Michigan dashboard to confirm radar-detected nocturnal migration and migration forecasts. This site does not scrape BirdCast.
The same page changes with the migration season, so this URL can build authority year after year instead of splitting spring and fall into competing pages.
Northbound migration builds from waterfowl and blackbirds into sparrows, shorebirds, warblers, vireos, thrushes, and flycatchers. Southerly winds are often the supportive directional signal.
Southbound migration progresses from shorebirds and early songbirds into warblers, vireos, thrushes, raptors, sparrows, kinglets, cranes, and waterfowl. Northerly winds are often the supportive directional signal.
The regional outlook combines National Weather Service forecasts with the count and recency of eBird species reports in each focal county. Favorable directional wind can strengthen a movement setup; rain may create a grounding watch; recent observations strengthen the case that a region is worth checking. Those are planning signals only. Radar-detected migration is verified on BirdCast, and local presence is verified through eBird and this site's county/species pages.
