Abstract: Animal feeders are disclosed that include a barrier limiting access to feed inside the feeder, doors controlled by an actuator and a control system configured to feed certain species to the exclusion of others by the recognition of those species. Cameras and, in some cases, other detectors are used to detect and identify animals by species. Doors may be configured to be open by default and remain open for the feeding of desired animals with the doors closing to prevent feeding upon the approach of an animal targeted for exclusion.

Abstract: Animal feeders are disclosed that include housings resilient to specific species, feed compartments resilient to selected species, a protected region in the housing, a barrier between the protected region and the feed compartment, an access door, a species recognition device, an access door actuator, a controller, and an arm projecting through the housing or the barrier.

Abstract: Animal feeders useful in feeding particular groups of animals are disclosed. Animal feeders described herein may, for example, include an electrically conductive exterior structure; a door; a door lock; a species recognition device; and an electric shock deterrent. Methods of feeding animals utilizing an electric shock deterrent are also disclosed.
