In urbanized areas, it is clear that secure nesting sites are limited. Even in rural areas, old snags are often cleared and wild borders eliminated by intensive agricultural practices, leaving little room even for beneficial species such as rodent-consuming barn owls or insect eating bluebirds. Many well intentioned individuals erect bird houses, but often these homes are imprecisely designed, or from garden centers or other "big box retailers" that offer decorative houses that birds never utilize. The houses we offer are built to exacting specifications for each species and are then field-tested for durability and occupancy.
