Nesting Box
Information on species-appropriate nesting aid:
The supplied rough wood must not be sanded smooth and needs to stay rough. This is important for the fledged young birds to be able to leave the
nesting box. If the wood is smooth, they have nowhere to hold on to! For any possible waterproofing you should of course only use wood protection
that is non-toxic and odourless.
Size of entrance holes:
The diameter of the entrance hole determines which birds can use the box. A well-dimensioned
entrance hole protects the inhabitants from predators and the weather.

Birds and matching entrance hole size:
Positioning of the nesting box:
It is important to make sure that the boxes are attached high enough to protect from predators. The entrance hole should be on the side pointing
away from the main weather direction and should be protected from direct sunlight. Nest boxes should be placed in autumn, because some types of
bird like to use them as sleeping places in winter.
Cleaning:
Nesting boxes need to be cleaned annually. This should be done in months when birds are not breeding. Only clean the nesting box with a brush and
hot water. Do not use cleaning products.

hole for the entrance hole with a suitable Forstner bit dependending
on the size required.
Now glue the back wall on with wood glue as shown in the drawing
and attach with seven nails.
Note: place the board for the door (5) as spacer between the side
panels.
Use a wood rasp or a belt sander to bevel the top edge of the back
panel to match the slope of the side panels. (see drawing!)

Nesting Box
Attach the wooden strip (4) with glue and at least two nails (9) to the
back panel of the nesting box. This strip is for attaching the nesting
box to a wall, a tree etc. You can add holes for screws or to attach a
wire or cord. You could also add a nail (9) at the same height on each
side and attach a cord or wire to hang the box up on a branch.
