Diurnal spacing patterns in kit foxes, a monogamous canid

Kit foxes (Vulpes macrotis) are socially monogamous and live in male-female pairs or small family groups. These small desert foxes are nocturnal and spend the day in an underground den. Mated pairs often shared the same den on the same day. However, on days when they did not share the same den, mated pairs did not occupy dens that were closer together (or farther apart) than expected by chance. Closely related foxes on adjacent home ranges also occasionally shared dens. However, foxes living on adjacent home ranges, even when closely related, also did not occupy dens that were closer together or farther apart than expected by chance.
