Easily increase the size of your local bird colony using these Esschert Design Plywood and Concrete Swallow's Nests. Rectangular, plywood backing handily supports these 4 concrete hemispheres, forming truly unique nesting spots for 4 of your feathered friends. The plywood bases affix easily to a wall directly beneath a roof overhang, keeping the units protected from the elements, and the concrete sections form welcome roosting spots for select birds. A 1.5" long and 2.375" wide, U-shaped opening on the front of each unit enables small swallows and house martins to enter, leading to a compact nesting area. A small opening on the base of each allows any water to drain from the nest, and the textured exterior offers a natural, aged effect. Predrilled holes in the plywood backing make placement against a wall simple, and the units are designed to sit flush against an overhang for thorough elemental protection. Invite additional birds to roost near you with these Plywood and Concrete Swallow's Nests.
