Designed for use with wooden nest boxes, the plate screws directly over the nest box hole to prevent squirrels, woodpeckers and other predators enlarging the hole to reach the young birds inside.
We recommend that nest box plates are fitted before the start of the breeding season in February to avoid disturbance of nesting birds inside.
Use the screws provided to fix the plate cover over the nest box hole.
28mm plates for blue tit, coal tit, crested tit, great tit, marsh tit, tree sparrow and willow tit.
32mm plates for great tit, house sparrow,tree sparrow, nuthatch, and pied flycatcher.
