 During the autumn months, our teams of volunteer hawk counters identify and tally 19 species of birds of prey, working under the leadership of an experienced dayleader. Hawks are counted systematically using a repeatable method, called the Quadrant System, so that data from different years can be compared. The count results help us look for trends and patterns in hawk populations over time.
