Range: Resident throughout the UnitedStates, southern Canada, and northern Mexico. Habits and economic status: The littlescreech owl inhabits orchards, groves, andthickets, and hunts for its prey in such placesas well as along hedge-rows and in the warm spells in winter it forages quiteextensively and stores up in some hollow treeconsiderable quantities of food for use duringinclement weather. Such larders frequentlycontain enough mice or other prey to bridgeover a period of a week or more.
