Abstract

Raptors are often described as highly visual predators possessing superior capabilities of visual resolution (e.g., Walls 1942, Pearson 1972, Shlaer 1972, Fox et al. 1976, Meyer 1977, Snyder & Miller 1978, Miller et al. 1989, Waldvogel 1990). Raptor visual capability was assessed in American kestrels (Falco sparverius) for this thesis. These investigations measured kestrel behavioral responses to visual stimuli in the laboratory.
