Experimental Effects of Hiking on Breeding Mexican Spotted Owls

  title={Experimental Effects of Hiking on Breeding Mexican Spotted Owls},
  author={Elliott C H Swarthout and Robert J Steidl},
On the Colorado Plateau, some environments occupied by Mexican Spotted Owls ( Strix occidentalis lucida ) receive a great deal of recreational use. To assess the effects of hikers on breeding owls, we quantified changes in the activity budgets of owls at nests in response to a controlled amount of hiking in canyons of southern Utah in 1997 and 1998. We examined differences in the duration and frequency of eight behaviors as well as in the type and frequency of owl vocalizations between hiking… CONTINUE READING
