Point Pelee National Park Trails Professional Review and Guide
"Point Pelee’s real claim to fame is as a bird-watching mecca. The number of bird species sighted here has reached 370. So many warblers–42 of the 55 species of American wood warblers–have been seen so far, and at least 36 of those are seen every year, that the park is known as the “warbler capital of North America.”
The spring migration, which peaks in mid-May, begins in late January or February, when horned larks appear, followed by ducks, blackbirds, geese and swans. In the fall, species often seen include buffbreasted sandpipers, golden eagles, merlins, northern sawwhet owls, peregrine falcons and red-necked phalaropes. The birding season is so important to the park, that staff open an additional 12km (7.4mi) of temporary trails for the spring migration, which are allowed to grow over after May."
