The Belvédère Raoul-Roy, a bird observatory located in the Parc national du Bic (Québec), is one of the best places in the province to watch migrating raptors. To date, 17 raptor species have been observed from the site, with the 2 most abundant being the red-tailed hawk (Buteo jamaicensis) and the sharp-shinned hawk (Accipiter striatus). A monitoring program was established at the site in 2002, and among its aims are the description of the abundance and diversity of raptors moving along the south shore of the St. Lawrence Estuary and the identification of favourable migration conditions for raptors. The program has helped document the temporal changes in spring migration of each of the species monitored and it has also provided information concerning population growth of species such as the turkey vulture (Cathartes aura), bald eagle (Haliaeetus leucocephalus), golden eagle (Aquila chrysaetos) and peregrine falcon (Falco peregrinus). A greater understanding of the spring migration of raptors should help inform conservation efforts, particularly environmental assessments for future wind farm projects in eastern Québec.
