Abstract: A bird nest box system is provided that includes a nesting enclosure, a moveable nest floor, and a floor movement mechanism that moves the nest floor between a lowered position and a raised position, the nest floor being mounted over the floor movement mechanism. The floor movement mechanism includes a driveshaft, a gear assembly coupled to the driveshaft and actuatable by rotation of the driveshaft, and a lift arm. The lift arm is actuatable by the gear assembly to rotate the nest floor toward a front opening of the nest enclosure. The gear assembly provides at least one gear reduction between the driveshaft and the lift arm.

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.
