Hillman Marsh Conservation Area

The shorebird half of a Point Pelee trip, and the reason to bring a scope.

Hillman Marsh sits a few minutes north of Point Pelee and does the job the park cannot. Open mudflat, managed water levels, shorebirds standing still at range. Most birders pair it with a Pelee morning, and almost all of them wish they had brought more glass.

Shorebird migration at Hillman Marsh, week by week

Late April to early June, then again July to September. Mid-May for spring shorebirds, when the shorebird cell is drawn down to expose flats.

  1. Late April – early June

    Spring shorebirds on exposed flats.

    What arrives

    • Dunlin, Least and Semipalmated Sandpipers
    • Short-billed Dowitcher, Black-bellied Plover
    • Yellowlegs, both species, often side by side for comparison
    • Dabbling ducks and herons through the marsh edges

    What it asks of your optics

    Everything is out on the flats at 80 to 200 metres, in worn or half-moulted plumage, and none of it is coming any closer. Pure reach and resolution.

    • A spotting scope

      This is the site that sells scopes. Shorebirds at this range are guesswork in binoculars and perfectly straightforward at 30x.

    • A stable tripod

      The flats are open and the wind comes straight across them. At 40x it’s the tripod underneath that decides what you can see, not the glass on top of it.

  2. July – September

    Happening now

    The longer, quieter southbound passage.

    What arrives

    • Adult shorebirds moving south from early July
    • Juveniles following through August and September
    • Pectoral and Stilt Sandpipers, godwits in some years
    • Egrets and herons concentrating as water drops

    What it asks of your optics

    A longer season with far fewer people than May, though heat shimmer off the flats usually puts an end to serious looking by late morning.

    • Quality scope glass

      Heat shimmer is brutal on cheap glass. Better optics buy you usable magnification for maybe an extra hour either side of midday, which is often the difference between a day list and a wasted drive.

    • A digiscoping adapter

      Juvenile shorebirds are the ones you want to photograph and puzzle out later. A phone adapter on the scope is the cheapest way to do it.

Hillman Marsh questions we get asked

Effectively, yes. Shorebirds on the flats sit between 80 and 200 metres out and stay there. Binoculars tell you something is present. A scope tells you what it is. If you only take a scope to one site on a southern Ontario trip, take it here.
Point Pelee in the morning for songbirds, Hillman in the afternoon for shorebirds. They are fifteen minutes apart and the species overlap is close to zero, so pairing them roughly doubles a day list.
The shorebird cell is managed, and water levels are drawn down for spring migration, so the best mudflat is usually there from late April into early June. Conditions vary year to year. Worth checking recent reports before you make the drive.
