Presqu'ile Provincial Park on the north shore of Lake Ontario is one of the most outstanding natural areas on the lower Great Lakes and a premier destination for birders during migration. Over 200 bird species are recorded annually at Presqu'ile, and about 120 species are known to breed there. However, it is the regular appearance of vagrants - visiting species whose normal range does not typically include the park - which draws birders from across the province and elsewhere. In total, 333 species have been recorded in Presqu'ile, many of which are not seen every year. It is also home to butterflies and dragonflies not typically found in the Ottawa area, and is well known as a stopover point for migrating monarch butterflies in the fall.
