Designed to protect. Built for survival.
This innovative nest box is engineered to deter predators and significantly improve fledging success. A smart internal tunnel and right-aligned entrance hole make it extremely difficult for predators such as cats, squirrels, and pine martens to reach the nest.
Small birds like Great Tits and Nuthatches can easily navigate the two-turn tunnel into the nesting chamber, while larger birds and mammals simply can’t twist or stretch their way inside.
Nest predation is far more common than many realise, with research showing up to 20% of nests are affected. The Seattle Predator Protection Nest Box was developed in response to this ongoing loss, offering a safer, more effective solution that truly makes a difference.
