SCHWEGLER 33
The Kestrel is a Bird of Prey that seeks its food on the ground. Farmers and foresters welcome it because of its preference
for Field Mice which, together with other types of mice, account for 80 or even 90 per cent of its diet. Kestrels
tend to remain in the same area. This nesting aid, which has been used to great effect for decades, can be easily and
flexibly attached to almost any surface using the strap supplied (e.g. with screw-in hooks, cable ties, clamps etc.)
Material: The Nest Box is made of SCHWEGLER wood-concrete, which has proved to be highly effective and
weather-resistant.
Bedding: To encourage the Birds to adopt the box a mixture of coarse sawdust, wood shavings and washed sand
should be moistened and placed inside.
Height above ground: Best 6 to 8 m (minimum installation height: 2.5 to 3 m).
Siting: On solitary trees, quiet places on the edge of woodlands, barns in open countryside, electricity masts, silos,
wind generators, etc. The following sites are recommended in urban areas: large buildings, high walls, chimneys,
industrial buildings, churches, etc. In the absence of trees the boxes can be installed on high poles to assist the
Birds in their hunt for mice.
Entrance hole: Facing south-east or away from the prevailing wind. Alternatively
under rafters, in recesses on historic buildings, in gaps in masonry, etc.
External dimensions: W 33 x H 36 x D 45 cm.
Interior of nesting chamber: W 30 x H 34 x D 30 cm.
Width of entrance: 17 x 24 cm.
Weight: approx. 13 kg.

Jackdaws are another endangered species. They live in colonies, and therefore several Nest Boxes should be

attachment have been designed to withstand the Jackdaw's tendency to "play" with things.
