Habitat and Ecology
In some localities it was observed during the early morning hours. Nests may be inside natural cavities of trees or built of leaves and sticks placed on branches of trees. Larvae and adult insects are common in the diet; peanuts, corn, oats, apples, peaches, mangos, plums, grapes, tomatoes, and anurans also are consumed. This species occasionally enters cornfields and can considerably damage ripening corn. Several females were recorded with embryos (2 to 4) in March, July, and August; two females on April were lactating; and a nest containing several small young was found in August in a hollow branch of a tree (Best 1995).
