Nest Box: A Sheltered Breeding Place in the Garden
Natural cavities are becoming rarer in gardens. A nest box creates a replacement and gives tits, sparrows and other hole nesters a safe place to breed. Unlike a feeding house it does not serve the feeding, only the breeding. Three things decide how well it works: the diameter of the entrance hole, a quiet position and the cleaning after the season.
The entrance hole decides
Who moves into the box depends above all on the diameter of the entrance hole. Around 26 to 28 mm suit blue tits, while 32 to 34 mm suit great tits and sparrows. The Kerbl nest box with metal roof for garden birds has an entrance hole of 35 mm and therefore speaks to the larger hole nesters. The metal roof protects the box from rain and extends its life in the garden. For parakeets in an aviary or indoors there is the Kerbl nest box for parakeets with 21 cm, which serves as a breeding cavity in the cage.
Position and cleaning
Hang the nest box facing east or south east if you can, so it catches the morning sun and does not stand in the full midday heat. A box tilted slightly forward lets rain run off instead of collecting on the lid. Choose a quiet spot away from paths and make sure that cats cannot simply get to it. Cleaning happens in late autumn, once the brood is through. Take the old nest out and brush the box out dry, then it is ready for new occupants again the following spring.
Frequently asked questions
Which entrance hole for which bird?
Around 26 to 28 mm suit blue tits, while 32 to 34 mm suit great tits and sparrows. The diameter therefore decides which species accepts the box.
Which way should the box face?
East or south east is best. That way the nest box catches the morning sun and does not heat up too strongly around the middle of the day.
When do I clean the nest box?
In late autumn, once the breeding season is over. Take the old nest out and brush the box out dry, then it is ready again in spring.
Nest boxes for garden birds and parakeets
Natural cavities are becoming rare, and a nest box creates a replacement. Who moves in depends above all on the diameter of the entrance hole. Around 26 to 28 mm suit blue tits, while 32 to 34 mm suit great tits and sparrows. The Kerbl nest box with metal roof for garden birds has an entrance hole of 35 mm and therefore speaks to larger hole nesters, and the metal roof keeps the rain off. For parakeets in an aviary or indoors there is the Kerbl nest box for parakeets with 21 cm as a breeding cavity. Hang the box facing east or south east if you can, not into the full midday sun. Cleaning happens in late autumn, once the brood is through. A box tilted slightly forward lets rainwater run off well. Choose a quiet spot away from paths that cats cannot easily reach.
