What the AI looks for in Birdhouse Accessories

Entrance hole size matched to target species: About 1-1/2 inch for eastern bluebirds, about 1-9/16 inch for western and mountain bluebirds, and about 1-1/8 inch for chickadees and wrens. Hole restrictor plates should match these sizes. The hole size decides which species can enter and keeps out larger competitors such as starlings.
Entrance hole protector: Metal portal guards fitted around the hole stop squirrels and woodpeckers from enlarging it. An enlarged hole lets in predators and invasive species.
Predator guard on the mount: Mount the box on a smooth pole with a stovepipe or cone baffle below it. A hole-extending block guard (Noel-style wire cage or wood block) helps stop raccoons and cats from reaching in. Predators climbing to the nest are a leading cause of nest failure. Trees and fence posts are hard to protect.
Mounting hardware fit: Check that pole brackets and flanges match your box's back-board dimensions and your pole diameter before buying. Universal claims often fail on thick cedar backs or non-standard poles.
Nest box cameras: The camera should fit inside the roof cavity without reducing floor space, and should use infrared rather than visible light at night. Bright light or a cramped interior can disturb nesting birds.

Coveside Conservation Products: Nest boxes and related hardware oriented toward bird conservation.
Woodlink: Broad range of birdhouses and mounting accessories.
Erva: Known for baffles and poles that also suit nest box mounting.

Perches added below the entrance; they help predators and house sparrows, not native cavity nesters.
Paint, stain or treatments on interior surfaces.
Mounting boxes on trees or fences with no way to baffle climbing predators.

No. Native cavity nesters do not need one, and a perch makes it easier for predators and competing species to reach in.
