Claim 9:
10. A bird nest box system comprising:
a housing defining a nesting enclosure, the nesting enclosure defining a front opening for a bird to enter and exit the nesting enclosure and an egg outlet at a back of the nesting enclosure;
a movable nest floor having a front end and a back end;
and a floor movement mechanism, the nest floor being mounted within the nesting enclosure and over the floor movement mechanism, the floor movement mechanism comprising:
a driveshaft; and
at least one floor actuation member coupled to the driveshaft and rotatable by the driveshaft to move the nest floor, wherein the at least one floor actuation member comprises a lift arm coupled to the driveshaft and having a distal end positioned to engage the nest floor forward of a center of gravity of the nest floor and lift the nest floor, the system further comprising a sliding pivot mechanism coupling the nest floor to the housing, the sliding pivot mechanism being positioned forward of the distal end of the lift arm,
wherein, with the nest floor in a lowered floor position, initial rotation of the driveshaft in a first direction raises the distal end of the lift arm, the distal end engaging the nest floor forward of a center of gravity of the nest floor, to raise a front portion of the nest floor, thereby tilting the nest floor toward the egg outlet, the sliding pivot mechanism allowing limited vertical and upward movement of the front portion of the nest floor; and
continued rotation of the driveshaft in the first direction further raises the distal end of the lift arm to raise the back end of the nest floor above the front end, thereby rotating the nest floor toward the front opening and to a raised floor position, the sliding pivot mechanism allowing the nest floor to rotate about the sliding pivot mechanism.
