Spring migration at Rondeau Provincial Park peaks in the first three weeks of May, when warblers, thrushes, tanagers, and flycatchers pour onto the Lake Erie peninsula after crossing the lake. The calendar only gets you close, though. The weather decides which days are great and which are quiet, so the best plan is a window of several days, not a single fixed date.
This guide covers when to come, how the weather shapes your birding, which species to look for, and where to find them. We’re Skye Hotel Ridgetown, just off Highway 401 in Chatham-Kent. Plan a few nights in the migration window, and you can be in the park on the best days. You can check availability for your May dates now.
When Is Peak Spring Migration at Rondeau?
Peak spring migration at Rondeau runs from early May to about the third week of the month. Those are the weeks when the greatest number and variety of songbirds pass through the park, and when birders arrive from across Ontario and beyond.
The variety is what makes it special. The Rondeau checklist includes 39 warbler species, and on good mornings in peak season, the Friends of Rondeau have reported more than 20 warbler species in a single day. Later migrants such as Blackpoll and Wilson’s Warblers are still moving through toward the end of the peak, and the Prothonotary Warbler stays to nest through May and June.
The park’s own calendar follows the same pattern. Rondeau holds its spring birding festival over these weeks. See our guide to the Festival of Flight in May for hike details and expected 2027 dates.
Why Does the Weather Decide Your Best Birding Days?
Songbirds cross Lake Erie at night, and they wait for favourable conditions to do it. Ontario Parks explains that the lake is a real challenge for migrants, so many hold back until the weather allows a safe crossing, then land on the three Lake Erie sand spits (Point Pelee, Rondeau and Long Point) to rest and refuel.
You can see this in the park’s own records:
- South winds bring birds in. One of the Friends of Rondeau’s migration reports credited south winds blowing across Lake Erie overnight for a fresh wave of warblers and songbirds, with treetops full of feeding birds the next morning.
- North winds slow things down. A Rondeau hike leader told CTV News Windsor that a week of north winds and cold weather made the birding very slow, and then the days that followed were excellent.
This is why a single day trip is a gamble. Arrive on the wrong day, and you may find a quiet forest. Stay a few nights, and you can watch the forecast, then head into the park on the mornings after the birds arrive.
That’s the main reason to base yourself nearby during migration. You’re not locked into one date. If the morning looks slow, rest, plan, and go back out when the wind turns.

The Prothonotary Warbler: Rondeau’s Speciality
The Prothonotary Warbler deserves its own note. It’s endangered in Canada and needs forested wetlands like Rondeau’s sloughs to breed. Rondeau’s chief park naturalist describes it as an almost guaranteed spring sighting along the Tulip Tree Trail, where it gleans insects from the water’s surface below the boardwalks. Listen for the male’s “zweet, zweet” song. Park staff have also put up nesting boxes in the sloughs to help the population.
Where Are the Best Spring Birding Spots in Rondeau?
These locations come up again and again in Rondeau’s migration reports and Ontario Parks’ trail notes:
| Spot | Why Birders Go | Good to Know |
|---|---|---|
| South Point Trail | Named the best birding trail in the park in past migration reports, with large warbler flocks | Ontario Parks currently reports the middle section is washed out. Check before you go |
| Tulip Tree Trail | Prothonotary Warbler nesting area, plus Hooded Warbler, Acadian Flycatcher and Summer Tanager | 1.2 km loop, mostly boardwalk. An all-terrain wheelchair is available from the Visitor Centre |
| Maintenance Loop | A regular warbler hotspot in the reports, including Cerulean and Northern Parula | Productive on busy migration mornings |
| Pony Barn | Connecticut Warbler, Northern Parula and Canada Warbler have been reported here | Worth checking on any warbler morning |
| Visitor Centre and garden feeders | Yellow-throated Warbler, Wilson’s Warbler and Red-headed Woodpecker have been seen here | The indoor birding window is a good option on rainy mornings |
| Spicebush Trail | 1.5 km loop where forest meets marsh. Ontario Parks rates it excellent for birding | A Connecticut Warbler has been reported here |
| Marsh Trail (evening) | Woodcock display flights, calling Whip-poor-wills and bitterns at dusk | 7.2 km one way along Rondeau Bay |
Just outside the park, the Blenheim Lagoons are good for shorebirds and waterfowl, with more than 235 species recorded. Access needs a permit from the Municipality of Chatham-Kent, so arrange it before your trip.
Is Rondeau or Point Pelee Better for Spring Migration?
Both are among the best spring migration sites in Canada. Rondeau tends to be quieter, with room to move on the trails. Point Pelee draws larger crowds.
At the 2023 festival, a Burlington couple told CTV News they prefer Rondeau because it’s less crowded and every trail stays open, with just as many birds. That same week at Pelee, crowds kept them from reaching the tip on several mornings. Rondeau’s broad peninsula also holds a lot of breeding habitat, so you get resident specialties as well as migrants.
You don’t have to choose. Point Pelee runs its own Festival of Birds in May, and Long Point is the third of Lake Erie’s migration sand spits. A base right off Highway 401 lets you pick each morning’s park by the forecast and the latest sightings.
What Should You Know Before a Birding Day at Rondeau?
- Buy your vehicle permit ahead. Ontario Parks sells daily vehicle permits up to five days in advance. Prices vary by park and season, so check Ontario Parks day-use fees.
- Confirm day-use hours before planning a dawn start. Call the Visitor Centre at 519-674-1768 for current hours and programs.
- Leave the speaker at home. The Friends of Rondeau have asked birders and photographers not to use electronic playback devices to attract birds in the park.
- Respect private property. Rondeau has private cottages inside the park. Migration reports have asked birders to keep groups small near them and to park at the Visitor Centre, not along the road.
- Dress for the lake. May mornings on Lake Erie can be cold. Bring layers and waterproof footwear.
- Watch for ticks and poison ivy. Both are present in the park, according to Rondeau’s alerts. Check yourself after each trail.
- Pack your food. A full morning in the field goes better with a packed lunch. The Park Store has a snack bar, but you’ll want to stay near the birds.

Plan Your Spring Migration Stay
Rondeau’s best birding days come with the right weather, and you can’t book that in advance. You can, though, give yourself a few nights in the first three weeks of May and be ready when the birds arrive.
