The Detroit River runs from Lake St. Clair in the north to Lake Erie in the south, forming part of the border between Michigan in the United States and Ontario in Canada. During the autumn months, the lower Detroit River becomes a corridor for the passage of migratory birds, and has gained international recognition for the annual volume of birds of prey. Hundreds of thousands of migrating hawks, eagles, falcons, and vultures are concentrated at this location where it is possible to systematically count them each year.
A standardized monitoring program - the Detroit River Hawk Watch - is conducted by the U.S. Fish and Wildlife Service (USFWS), the Detroit River International Wildlife Refuge (DRIWR), and its friends group, the International Wildlife Refuge Alliance (IWRA), at the Lake Erie Metropark in Gibraltar, MI. Join us at the Boat Launch and witness spectacular flights of Broad-winged Hawks, Turkey Vultures, Sharp-shinned Hawks, and both Bald and Golden Eagles! See the Calendar of Hawk Movement below for numbers and types of raptors expected each season.

concentrate at the lower Detroit River each September after nesting in deciduous or mixed-deciduous forests of Ontario. Tens of thousands of these raptors will pass overhead on their way to wintering areas in South America.
