Detroit River Hawk Watch entering 41st year

The Detroit River Hawk Watch (DRHW) is excited to announce the upcoming 41st year of monitoring diurnal raptor and turkey vulture migration at the mouth of the Detroit River beginning Sept. 1. This season will be the 26th year of consistent coverage at the Lake Erie Metropark and the seventh season the DRHW is welcoming back professional hawk counter Kevin Georg.

Last season, with the help of dedicated volunteers, Kevin conducted 573 hours of data collection over 87 days and tallied an astounding total 145,577 turkey vultures and raptors across 15 different species. This total was 16% above the Long-Term Average (LTA) of roughly 125,048 raptors counted by the Detroit River Hawk Watch at Lake Erie Metropark between 2013-2022. We compared this season’s totals to the respective LTA for each species since 1998.

In 2022, turkey vulture (26%), broad-winged hawk (13%), American kestrel (10%), merlin (59%), and peregrine falcon (28%) were the only species counted above the LTA. Osprey (-84%), bald eagle (-42%), northern harrier (-12%), sharp-shinned hawk (-2%), Cooper’s hawk (-77%), northern goshawk (-87%), red-shouldered hawk (-24%), Swainson’s hawk (-100%), redtailed hawk (-4%), rough-legged hawk (-88%), and golden eagle (-52%) were lower than their respective LTA. Two northern goshawks and zero Swainson’s hawks were counted this year. There were no “unknown” raptors counted this past season.

Because DRHW is located in a major flyway, our site’s numbers represent only a sample of the overall migration. A lower count at DRHW may mean an elevated count at a neighboring site! Raptor count data are entered into a database managed by the Hawk Migration Association of North America to facilitate collaboration and allow more accurate estimates of raptor population health than assessing one raptor count site alone could offer.

You can visit the Detroit River Hawk Watch daily from Sept. 1 through Nov. 30 near the boat launch at Lake Erie Metropark located at 32481 West Jefferson, Brownstown, MI 48173.
