First Report on the Diet of the Chaco Owl (Strix chacoensis) in the Monte Desert, Argentina

Results suggested some temporal variation in the Chaco Owl’s diet composition, although sample sizes were too small for statistical analyses. Rodents and scorpions were taken during all seasons, but the former were mostly consumed during winter and the latter during spring-summer. In addition, insects were absent in the winter diet, but constituted a large proportion of the spring and summer diets, indicating that Chaco Owls respond to the seasonal availability of their prey, as do Rufous-legged Owls. The high consumption of scorpions reflected the high availability of this prey in semiarid environments. Predation on silky mice and pallid fat-tailed opossums suggested that Chaco Owls hunted throughout the available habitats: silky mice are strongly associated with grasslands, whereas pallid fat-tailed opossums inhabit both shrubs and rocky areas with scarce vegetation near watercourses.
