Eastern woodrats (Nemotoma floridana) are medium-sized, nocturnal rodents that collect sticks and other objects as house building materials.

Woodrats range from their houses to retrieve sticks and thus offer the opportunity to examine central place foraging for nonfood items. This paper examines procedures for determining the stick size-value relationship for woodrats initiating house building
