The 1B is the bestselling nest box for garden birds and one of the official nest boxes of BTO's National Nest Box Week. The 1B nest box will attract a wide range of species with different entrance hole sizes available to prevent birds from competing with each other for the boxes. The 1B is available in four colours: brown, green, white and red. The nest box can be attached to the tree using an aluminium nail or by hanging over a branch.
Order the 32mm entrance hole to attract Great-, Blue-, Marsh-, Coal and Crested Tit, Redstart, Nuthatch, Collared and Pied Flycatcher, Wryneck, Tree and House Sparrow and bats.
The 26mm entrance hole suits Blue-, Marsh-, Coal- and Crested Tit and possibly Wren. All other species are prevented from using the nest box due to this smaller entrance hole.
The Oval entrance hole (29x55mm) suits Redstart and all other species which nest in the 32mm boxes. However, because more light enters the brood chamber it is preferred by Redstarts.
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.
23cm high x 16cm diameter. Aluminium nail and hanger included.
