The sturdy plastic pieces snap together with plastic screws to form a two story red, grey, and white barn.
Has slip resistant floors, landing and take-off rails on each floor, and swing-up doors for easy cleaning.
Each room measures 6" x 6" x 6" for the nesting martin families, but if you'd like larger compartments and fewer families, you can easily adjust the inner compartments to 6" x 6" x 12" in order to create ten nesting sites.
The entrances to the four uppermost apartments allow you the option of round or crescent shaped openings.
Ventilated door panels provide maximum comfort, and the crescent-shaped starling resistant entrances deter pest birds looking to usurp your rightful martin tenants.
Overhangs, gutters, and rails also help protect martins and their eggs.
