Hanging Nesting Boxes - The Best Tips and Hints
In Germany, bird protection is very important. One of the measures is to hang nesting boxes, which will also delight the garden owner with birdsong.
Optimal entry hole for all bird species
Not every nesting box is suitable for every type of bird. Wagtail, spotted flycatcher and common redstart nests like robins, wren and blackbird in semi-open boxes. Incubators with a 28 millimeter infeed hole are suitable for blue or coal tit.
Coal and crested tit need 32 millimeters in flight. Oval entry holes of 34 millimeters attract field and house sparrow, nuthatch or redstart. Great spotted woodpeckers and starlings prefer to inhabit boxes with 45 millimeters of strong entry. For jackdaw and pigeon is a Einführloch to 80 millimeters, for the Tawny Owl one to 130 millimeters. The dimensions of the boxes are secondary. Cavities fill the birds with nesting material.
Think of thermal insulation, but do not fill it specifically
A bird house should always be made of wood, wood-concrete or pumice. The reason for this are the heat-insulating properties that alternative materials such as plastic and metal do not meet. A common mistake when hanging nesting boxes is the interior. Even a self-made incubator, the home improvement should not equip with materials. As soon as the birds start to nest, they procure the required material independently.
For self-made nesting boxes, take note of safety
Anyone who wants to build nesting aids themselves, screws 20 mm thick wooden boards and drills small ventilation holes in the floor. For weather resistance you should treat the box with linseed oil, but not for the bird's health with wood preservative or paint. The Einfluglochunterkante on the front wall must be 17 centimeters above the box floor and the top edge is decorated with a canopy.
Not too many small area nesting aids
If the gardener wants to invite various birds to his garden, he must keep a distance of at least three meters between the nesting boxes true. For boxes of the same type, the distance should be ten meters.
One box is sufficient for every 100 square meters. Only star boxes and spar boxes may hang closer together. The number of nest boxes in a garden depends on the size of the food and the size of the garden. The garden owner can support the food situation by hanging sunflower seeds, as most songbirds eat them.
Safe Cave at a Safe Height
When hanging up the rain boxes, the bird lover considers predators and climatic influences. The incubators hang in sheltered places at a height of at least two meters. Walls, garages, beams, roof bases or gables and trees are suitable as a carrier. Free approach to the entry hole and an entry opening with north, northeast or east orientation ensure safety and weather protection. The box should lean forward slightly so that neither rain nor hail can penetrate.
Take care of the tree while hanging up
So that the nesting box respects the well-being of trees just as much as birds, not nails. They can start to rust and damage the tree. The hobby gardener therefore uses a wire hanger sheathed with garden hose to suspend the hides.
Cleaning and moving in every fall again during the autumn
The optimum time to hang the nesting aids is autumn. The birds have enough time to discover and get to know the incubator before the breeding season. If the fledglings are fledging the following autumn, the garden owner should use a hard brush and warm water to clean the nesting box so that a new family can move in.
