Structures offered at the retail chain provide shelter for avian species. These manufactured dwellings, designed to mimic natural nesting sites, come in various shapes, sizes, and materials. For instance, a simple wooden box with an entry hole is a common design.
Providing these artificial habitats contributes to local biodiversity by offering safe havens for birds, especially in areas where natural cavities are scarce. Historically, people have constructed these shelters to attract birds for pest control, aesthetic enjoyment, and ornithological observation.
