How large is the nesting space and why does size matter?

The interior accommodates adult barn owls and provides room for a family, with overall dimensions of 15.8 × 10.6 × 8.7 inches. A roomy cavity helps birds feel secure and lets parents move comfortably when tending chicks. Size also improves ventilation options and reduces crowding-related stress.

• Interior volume sized for larger owl species and broods
• Room to install natural nesting material without packing the cavity

How does this box perform outdoors throughout the seasons?

The nesting box is intended for outdoor use and sized to provide shelter from wind and rain when mounted correctly. Proper placement—facing away from prevailing winds and under modest overhang—helps keep the interior dry. Routine checks after severe weather keep the cavity in good condition for occupants.

• Designed for outdoor placement on poles, posts, or building ledges
• Mount where water runoff and prevailing winds are minimized
• Simple maintenance and inspection recommended after storms

What should I know about attracting owls to this box?

Placing the box in a quiet area with open hunting grounds nearby increases the chance of occupancy. Mounting it 10–20 feet high, away from heavy human traffic, and keeping the entrance unlit at night helps owls feel secure. Avoid placing food sources too close to reduce unwanted predator attention.

• Choose a quiet, open location with good hunting habitat nearby
• Mount at recommended height and avoid frequent human activity
• Keep entrance area free from artificial lighting and food attractants
