Boundary Bay Professional Review and Guide
"Tucked into the southwest corner of the 16-km (10-mile)–wide Boundary Bay, this regional park provides opportunities to view large concentrations of wintering and migratory birds. Like the Fraser estuary, the tidal bay is an important stopover in spring and fall for geese and shorebirds on their way between their northern breeding grounds and the southern regions where they pass the winter. Migrating birds must pause during these arduous journeys to rebuild their energy by resting and feeding, and so we witness the arrival and departure of flocks of western sandpipers, dowitchers and yellowlegs as well as hundreds of Brant geese.
Some shorebirds, such as sanderling and dunlin, go no farther, but winter in the bay along with thousands of ducks and diving birds. Resident hawks, owls and eagles are joined in winter by fellow raptors; swallows and warblers fly in for the summer to share the pickings of the fields inside the dyke. Highlights: Tidal lagoon, beach, dunes; dune plants, field flowers; gulls, shorebirds, ducks, raptors; cottontails, muskrats. Terrain: Flat. Dyke, foreshore and field path."
