The 2GR nest box was designed with the assistance of senior forest rangers to provide nesting birds with extra protection from predatory species and mammals. The uniquely protected entrance panel on this box will protect resident birds from cats, magpies, jays and martens. With a choice of oval or three-hole entrance, the nesting chamber is well lit despite its size. This means that birds will construct their nest very low down at the rear of the box, away from the reach of predators. The front panel, with its integrated protection, can be easily removed for inspection and monitoring, providing an unobstructed view of the nest.
The single oval entrance hole (30mm x 45mm) suits coal-, marsh-, blue-, great- and crested tits, redstart, nuthatch, collared and pied flycatcher, wryneck, tree and house sparrow and bats.
The three-hole 27mm entrance is suitable for blue-, marsh-, great tits. Due to the small size of the entrance no other species is able to enter this box.
An additional recess suitable for bats has been created inside the roof space of the 2GR.
These Woodcrete nest boxes are famous for their durability - lasting for at least 20-25 years. Woodcrete is a blend of wood, concrete and clay which will not rot, leak, crack or warp. They are backed by leading ornithologists, nature conservation organisations, government agencies and forestry experts. Schwegler boxes have the highest occupation rates of all nest boxes and are carefully designed to mimic natural nest sites and provide a stable environment for chick rearing and winter roosting.
