Wildlife Viewing.
Heart Lake's glacial kettle holds spring and fall waterfowl on the open water and migrating passerines through the surrounding upland forest along the TRCA trail network. Claireville Conservation Area's 848 hectares of West Humber wetlands and meadow habitat — the largest CA in the GTA — carry urban-region birding through the spring and fall migration windows, with reservoir-edge waterfowl at the flood-control dam pond.
The Etobicoke Creek riparian corridor through the city's parks adds opportunistic urban-fringe sightings between the two big TRCA properties.
The brief.
Spring waterfowl peaks late March through April on the Heart Lake kettle and the Claireville reservoir; expect mergansers, scaup, ring-necked ducks, and the resident Canada-goose population. Fall passerine migration runs September through October through the upland forest at both sites — warblers, vireos, and thrushes during the peak weeks.
The Heart Lake forest also holds local woodpecker and resident-songbird populations year-round. The Claireville reservoir's flood-control dam pond holds wintering ducks during cold snaps when smaller bodies freeze.
The Etobicoke Creek riparian corridor adds urban-fringe sightings — green herons, kingfishers, and migrating songbirds — between the two main sites. All TRCA sites are free or modest day-use; bring binoculars.
