Notes	Due to Covid, we ran the route in 2 2 car caravans, splitting the route in half,instead of a single car with 3- 4 observers. We totaled an incredible 33 Rough-legged Hawks; the hypothesis -these birds had moved further S when the cold and heavy snow cover hit N IL and WI. As the temperature began to moderate and the snow cover lessened, these birds were moving back N, and we caught them as they moved through the area. With the 7 we counted on the LaSalle route conducted on this same day in the AM, we had 40 Roughlegs in total!
