Hawk Watch! - 14 Sep 2013
If you look at the 30 year data for the Detroit River Hawk Watch you'll see that Broad-winged Hawks outnumber all other raptors this time of year. When conditions are favorable a day-count of 100,000+ birds is possible! This usually happens within 3-4 days of the 17th of September.
At approximately 10 am, after the first hour or two of really slow flight several large kettles of Broad-wings started forming over Canada. Within minutes the birds started streaming north and passed overhead. Unfortunately the birds were high enough in the blue skies that naked eye viewing was next to impossible. I managed to to get the scope on one kettle, and digiscoped this short video.
I would leave shortly afterward, and the day would end up being fairly successful. But the 'big' flight never materialized. A summary of the day's count can be found at HawkCount.
