This unit is an extended version of our proven Swift Box No. 17 which has been successfully used for decades in all kind of construction projects. It combines 2 independent swift compartments with very easy installation.

The lightweight nesting box made of non-asbestos vegetable fibre material for installation on the external walls of buildings of all kinds, including houses, industrial premises, churches, roadside structures, walls or even cliffs.

Two fixing brackets and screws/plugs are included. Please check for suitability of the mounting material provided..


Siting & Positioning:
Under or close to roofs, at least 5m from ground. Please ensure unobstructed access for birds entering and leaving the box. The installation of several boxes in a building will assist the rapid formation of swift colonies. Verify safe hold of the box after installation.

Cleaning & Inspection:
Cleaning is easy and convenient with this box but is not essential. The box can be easily opened by rotating the circular plate containing the entrance hole by 90° into vertical position and removing it. Swift nests are always located in the darkest corner as far away from the entrance hole as possible. After replacing the plate: Latch the front plate by rotating the entrance hole into horizontal position.

Nest Boxes can be painted to match the house wall - it is very important to ensure that you always use paint that is air-permeable.
