A dog feeder that includes a base, a lid, and a coupler. The base includes a left wall and a right wall that extend vertically away from a tray between the left wall and the right wall. The tray is configured to contain dog food. The lid includes a front side and a back side, where the front side includes a protrusion that protrudes outwards away from the back side. The coupler couples the base to the lid such that the lid is capable of swinging between the left wall and the right wall. The protrusion is configured such that when a head of a dog pushes against the protrusion to swing the lid to expose the tray, ears of the dog do not reach an edge of the lid.

A system for limiting access by flying animals to fans of an air-cooled condenser comprises a plurality of perimeter netting segments and interior netting segments. The fans are mounted on a framework and arranged in a matrix. Each fan comprises either (i) a perimeter fan positioned along any one of three or four outer edges of the matrix or (ii) an interior fan. Each perimeter netting segment is adapted to be positioned at least partly below a corresponding one of the perimeter fans. Each interior netting segment is adapted to be positioned at least partly below a corresponding one of the interior fans. Each perimeter netting segment has a first edge adapted to be affixed to the framework and a second edge affixed to a corresponding interior netting segment. At least a portion of each perimeter netting segment is angled inward and downward toward its corresponding interior netting segment.

A modular pest deterrent kit is configured to mate with one or more types of pole tops. The modular pest deterrent kit comprises a spike having a first coupling member and a base having a second coupling member configured to mate with the first coupling member. The base is contemplated to have a first bottom surface. An alternative base is contemplated to have a third coupling member configured to mate with the first coupling member. The alternative base has a second bottom surface, which is differently shaped from the first bottom surface.

A nesting deterrence device for elevated infrastructure is designed to be mounted within a deterrence area on elevated infrastructure, such as cell and data towers, utility poles, sports lighting, and the like, in order to deter raptors (i.e., Osprey) and other birds with relatively long wingspans, greater than 33 inches (84 centimeters), from entering into a deterrence volume immediately above the deterrence area. Birds are deterred from flying through the deterrence volume by a plurality of deterrence rods, spaced and oriented within the deterrence volume, which would interfere with bird flight. Because birds would be prevented from freely flying through the volume, they would be unable to alight and nest in the deterrence area below.

A bird guard assembly and methods for installing on a roof for preventing bird nesting underneath a solar panel. The assembly includes a bird guard with a rail arranged for abutting at least a part of a frame edge of the solar panel and a bird barrier for extending to the roof and a fastener comprising an arm and an arm sleeve arranged for only cooperating with the arm in a fastening direction for fastening the rail to the frame edge.

A protective apparatus for a distribution line conductor includes an elongate tube configured to be installed on the conductor and a plurality of annular members concentrically positioned on the tube and configured to rotate independently of each other. The tube has a longitudinal axis and defines a longitudinally extending chamber configured to receive the conductor. The tube has opposite first and second ends and a longitudinally extending opening from the first end to the second end that facilitates installation of the elongate tube on the conductor. Each annular member includes an outer surface and a plurality of circumferentially-spaced apart members extending outwardly from the outer surface. Each annular member includes a longitudinally extending slot that is configured to align with the longitudinally extending opening of the tube to facilitate installation of the elongate tube and the plurality of annular members as an assembly on the conductor.
