Gray hawks (Asturina nitida) range from the Amazon Basin in South America into the southwestern United States. They are migratory in the northern part of their range, arriving in southern Arizona and extreme south Texas in the spring to breed, and occasionally entering New Mexico. These northern members of the species generally depart in mid-October to overwinter in Mexico, although they can be found in south Texas year-round, and rare records exist of winter residents in Arizona. Further south in their range, gray hawks are non-migratory (Glinski, 1998; Kaufman, 2000; Stiles and Skutch, 1989; Terres, 1980).
