Developed in collaboration with Senior Forest Ranger Dr. Otto Henze ().
The design of this nest box and its front panel provides effective protection against cats and martens. With its choice of oval or three-hole entrance, the nesting chamber is well lit despite its size. Because of the light entering, the nest is built very low down at the rear of the box, away from the reach of predators. The front panel, with its integrated protection against cats and martens, can be easily removed for inspection and monitoring, providing an unobstructed view of the nest.

With its enlarged brood chamber and predator protection, the 2GR is widely used in parks and woodlands. A common feature of monocultures is the prevalence of attack by insects and other pests; the 2GR helps by encouraging a higher breeding success by birds that eat pests.

The box is supplied with a hanger and aluminium nail.

NEW: An additional recess suitable for bats has been created inside the roof space. See Fig. 3.

2GR Nest Remover:

(only for use with the 2GR)

Please see Fig. 7 and Fig. 8.

This is used in the 2GR nest box for inspection and cleaning purposes. The aluminium plate is carefully slid between the nest and the floor of the nest box. This enables the entire nest to be removed from the 2GR nest box without the need to touch it.

This is also a wonderful means of acquainting children and young people with nature. The nest can be easily replaced after inspection.
