Abstract: A bird nest box system is provided including a housing defining a nesting enclosure, a movable nest floor, and a floor movement mechanism. The nesting enclosure has a front opening and an egg outlet at a back of the nesting enclosure. The nest floor is mounted within the nesting enclosure and over the floor movement mechanism. The floor movement mechanism includes a driveshaft and at least one floor actuation member coupled to the driveshaft and rotatable by the driveshaft to move the nest floor. From a lowered floor position, initial rotation of the driveshaft in a first direction moves at least one of the at least one floor actuation member to tilt the nest floor toward the egg outlet. Continued rotation of the driveshaft moves the at least one floor actuation member to rotate the nest floor toward the front opening and to a raised floor position.
