Claim 12:
13. 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, with the nest floor in a lowered floor position, initial rotation of the driveshaft in a first direction moves at least one of said at least one floor actuation member to tilt the nest floor toward the egg outlet; and
continued rotation of the driveshaft in the first direction moves the at least one floor actuation member 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,
wherein the at least one floor actuation member comprises a lift cam member mounted to the driveshaft, wherein the nest floor further comprises a cam follower and the lift cam member engages the cam follower, a position of the cam follower being adjustable along a lengthwise direction of the nest floor to thereby adjust the angle of inclination for the lowered floor position.
