Abstract
The present invention relates to avian enclosures which are rotated. The invention is presented as a separate electrical device that rotates birdhouses and/or birdfeeders or it can also be made part of the whole enclosure. The electromechnical device that rotates the avian enclosures basically consists of a power source, a motor, and a gearbox. Power is supplied from batteries, and/or solar cells, or an alternating current source. A more complex version of the present invention is also presented that incorporates an electronic circuit to sense the presence of birds and activate the motor only for a predetermined period of time. Consequently, the main purpose of this circuit is to conserve power which is very important for non-rechargeable batteries.
