[email protected] Introduction Hawk migration counts are often carried out at lookouts, or watchsites, which are generally at concentration bottlenecks or along leading-lines (Heintzelman 1975b, 1986; Zalles Bildstein 2000). Data produced at these hawk-counting sites are difficult to use effectively because they are collected under widely varying conditions with many variables. Observer experience, optical equipment, lighting conditions, flight patterns of the birds on a given day, weather conditions, observation hours, and number of observers are some of the variables that can influence the data being collected (Heintzelman 1986; Bednarz and Kerlinger 1989; Bildstein 1998; McDermott 1998).
