Dipper Nest Box No. 19 is very popular for securing existing stocks or restoration of streams, etc. As it is secure against small predators, hatching successes are significantly better than in natural nest location.

Dipper and Pied Wagtail Nest Box No. 19

Occupants: Dipper and Pied and Grey Wagtails, around buildings also Black Redstarts.
Fixing: The brackets are adjustable and easy to install using screws or bolts.
Cleaning: Because Dipper nests are usually infested with parasites it is advisable to clean the nest box after the breeding season (i.e., from August onwards).
Material: Plant fibre and wood-concrete (100 % asbestos-free).
Siting: Under bridges and on vertical walls which are directly adjacent to natural, moving water which should be relatively clean. The No. 19 should always be installed at least 0.5 m above the high water line. Practical experience has shown that the box should always be placed above deeper, flowing water, because Dippers tend to dive into the water if danger threatens. For the Pied Wagtail, the No. 19 can also be used in wetlands.
External dimensions: approx. W 19 x H 19 x D 37 cm.
Internal dimensions: 18 x 18 cm.
Weight: approx. 4.7 kg.
