In 1988, HBMO persuaded Detroit Edison to donate a 40 foot Hawk Tower which is now at the site. Southwestern Ontario has a funneling effect on migrating raptors due to the geography of the nearby lakes and the reluctance of most raptors to cross large bodies of water. Birds gain altitude over the flat farmland to the north and east, rising easily with the thermals that such areas provide in abundance. As the birds head south they meet Lake Erie and, reluctant to cross it , turn west. Clear, cool, and gusty NW winds all day.
Great cloud cover for birds.
Sunny and cold in the morning, heavy cloud cover in the afternoon. Good looks Several large flocks of Tree Swallow migrated. Hundreds of birds. Near our platform were 3 Lincoln's Sparrows, seemingly feeding on the developing Bur Marigold seeds. On the lake 2 Lesser Black-backed Gulls had been seen.
