78. Tommy Thompson Park, Toronto, Ontario

Find cormorants, night-herons, warblers, thrushes, owls, shorebirds, waterfowl, and egrets at this globally significant Important Bird Area on Lake Ontario.

The Leslie Street Spit, a man-made peninsula that is home to Tommy Thompson Park, has been colonized by a remarkable variety of plants and animals, including more than 300 bird species. The Tommy Thompson Park Bird Research Station, a monitoring and education initiative, is located on Peninsula D.

The park is one of my favorite places to go birding because the mosaic of landscapes provides habitat for a wide variety of species year-round. Activity is highest during spring and fall when migrating songbirds and shorebirds pass through. I often stop in the Wet Woods, south-southwest of the parking lot, in search of warblers, flycatchers, orioles, and other songbirds during migration.

Summer breeding season attracts more than 50 species to nest, including large colonies of Double-crested Cormorants and Black-crowned Night-Herons. Winter is only slightly calmer as ducks and owls (including Boreal Owl and Northern Hawk Owl in 2008) find refuge here. To me, the most amazing aspect of Tommy Thompson Park is that all of this diversity is found within a major urban center. — Tom Flinn
