Today, I heard about Hawk Ridge Nature Reserve in Duluth, MN. Last year, Hawk Ridge saw over 101,000 broad-winged hawks migrate overhead in a single day. On the 16th of this month, Hawk Ridge saw over 31,000 broad-winged hawks migrate overhead in a single day. I'm generally happy to get a few different bird species to my backyard feeders on a regular basis and to see a single hawk or two on a car trip. I cannot imagine what 31,000 or more hawks flying overhead must look like. I'll have to add "Hawk Ridge in September" to my list of Places to See.
