Many of our buildings are inhabited by different species of birds and bats, which make use of the cavities present there. Below we show you some species for which the habitat at our houses is very important and how we can help them.

Bats:

Bats like to live behind wall coverings and shutters, in wood piles, roof trusses or nesting boxes. They also like to live in church towers or tree caves.

Swifts:

Swifts are cave breeders and like to build their nests e.g. in roof cavities of older buildings. In the meantime, the building renovation often closes the entrances and converts old attics into living space. As a result, he can no longer find breeding grounds and is dependent on our help.

You can find a good example here.

Swallows:

Swallows build their nests from loamy earth on facades. These are protected by the Federal Nature Conservation Act all year round and must not be damaged or destroyed. Since the nesting possibilities are strongly limited due to the modern house building with flat roofs or smooth plaster, they are dependent on our assistance. For this purpose the LBV has initiated a swallow aid project, where you will find detailed instructions on how to offer the swallows living space.

House sparrows:

The establishment of niches, wall gaps or facade greening with new buildings or building reorganizations are very helpful for the house sparrow, since it can build its nests here. Hedges and trees are also an important place for retreating, nesting and wintering. In addition, an area with native grasses, shrubs and bushes can be built in the garden, where the birds can find more insects for their young. At the same time, in winter the seeds serve as food for the birds.

Jackdaws:

In the nature, the jackdaws hardly find breeding places any more, therefore, some brood in our house-chimneys. It can happen that the chimney is clogged by twigs, clay, grass etc., which can be dangerous for humans and should be reported to the chimney sweep. A chimney cover grille installed by a specialist offers protection against this. The Dawennests may be pestered or eliminated only by agreement of the authorities, since they stand under protection.

What nesting aids are available?

Depending on the species, there are different nesting boxes, nesting stones or individual solutions for birds, such as wooden constructions. Bats like to use crevice quarters with abdominal and back contact to the wall or roof tiles to get into the rooms behind. Here are some examples of nesting aids:

How can they be attached?

There are several ways to do this. On the one hand, the nesting stones can be inserted into the thermal insulation during (preferably planned in advance) or after renovation. On the other hand, nesting aids can be mounted on the façade and also former or still active chimneys can be used as crevice quarters for bats.

Good instructions on how to install them can be found in the BUND practical manual. Please also note the building and incubation calendar there.

How do I clean the quarters?

Since bat quarters are usually specially constructed, cleaning is not necessary. The parents of the birds usually keep their nests clean themselves, which is why the nesting aids do not usually have to be cleaned either. For species with a lot of nesting material such as the house sparrow (best after the breeding season in late autumn or winter) can be cleaned. It is usually sufficient to sweep out the box roughly. Before cleaning, make sure that a dormouse or a dormouse hibernates there.

Often there are concerns that the animals will pollute the house walls, but this is usually unfounded and can be prevented by simple means. For this purpose, a manure board can be placed under the nesting aids at a distance of 50 cm.

What else can you do?

For example, feeding birds on the balcony:

If you don’t have a garden, but still want to feed birds, you can do this from the balcony, for example. In order to make this as dirt-free as possible, you should only buy high-quality food with few fillers. For food without shells such as peanuts, oat flakes, coarsely ground maize, peeled sunflower seeds or yellow millet there is also less waste.
In addition, it is advisable to observe which bird species come into the garden and then buy suitable food for them, as they will also have to sort out less. In addition, a collecting tray, which can be placed under the feeding area, is helpful. However, this must be cleaned daily, as excrement and falling food can mix here.

Land owners can also create hedges, flower meadows or ponds to increase the incidence of insects and thus improve the food supply. In the garden and meadows pesticides should be avoided and old, hollow trees should be preserved as an ideal nesting place.
