The Purple Martin Migration House
This is the 12-unit bird house designed specifically for the mosquito-eating purple martin. The communal birds migrate to South America every fall and return to North America every spring to breed—often to the same nests. This house contains a dozen 6″ x 9″ compartments and features small, crescent-shaped doors, that keep out predators and other birds that compete for the same dwellings. It’s constructed from polypropylene copolymer plastic (PPC), has four perches, nesting bowls, slip-resistant floors, and built-in water drainage. With a 12′ H x 2″ diameter pole.Price $149.95
