The invention relates to a freely suspended bird nesting box. With such nest holes it is customary to mount the entry opening as high as possible above the nest floor and to keep it very narrow to match the body size of the bird. The invention has the task of providing a nesting cavity create that is suitable for cave-breeding birds and also for semi-cave-breeders. For example, was an occupation with marsh tits, blue tits, great tits, coal tits, crested tits, blackfly tugs, Redstart and Black Redstart preserved.

Decisive for the design was the desire to give the brooding bird a safe and pleasant one To create a stay and to reach the young birds (preferably the weaker young birds) to facilitate the entrance hole. The prerequisite for this is that the entrance hole is much deeper will.

According to the invention, the lower edge of the entry gap is now at a height of 60 to 120 mm, preferably 80 mm above the deepest point of the bottom of the nest cavity interior, and the floor runs approximately from the middle of the interior of the nest cavity to the lower edge of the entrance gap sloping upwards. It turned out to be beneficial if this rising part of the ground with notches, steps or the like. Was provided.

In the drawing, an advantageous embodiment of the nest box according to the invention is schematically shown. It shows

F i g. 1 shows a vertical section through the entrance opening and

Fig. 2 is a section along the line II-II of Fig. 1.

The in F i g. 1 the nest box shown is suspended from the eyelet 1 by means of a wire, swinging freely, namely, it is advantageous to use two eyelets, as this makes it easy to turn the nest cavity can avoid which, in particular, would make it more difficult to approach the flight hole. The eyelets 1 should so far above the center of gravity of the asymmetrically designed nest cavity that this hangs vertically. 2 shows the sloping, approximately conical roof, which at 3 turns into a vertical, so roughly cylindrical part passes. At 4, a drip tray is indicated that the from Roof allows water to drip off freely so that the walls of the nest box are not unnecessarily damp will. The part 5, which is in front of the entrance hole, can be made larger so that the entrance hole is further reconsidered and in this way too

inclined rain does not get into the nest cavity. In the case of the entrance hole 6, which is designed as a flight gap the upper limit is designated with 7 and the lower limit with 8.

So the entrance hole is in the front closure 9 of the nesting cavity. A small metal tab 10 is folded over after the insertion of the closure part so that it holds and supports the closure part. The bottom 11 of the nesting cavity rises in steps at its flight hole-side edge at 12, so that the lower edge 8 of the flight hole 6 appears as the last step of this stair-like rise surface. This makes it possible for the bird parents to transport smaller sick young birds out of the nest; Larger sick young birds can also climb up to entry gap 6 when they are hungry to attract their parents. The enlargement of the nest space by means of the rising surface has the additional advantage for the young birds that they can crouch outside of the original nest when they get bigger. As a result, the plumage in particular can be cleaned better, which can be of vital importance for the first, most dangerous time after the flight. Since the nesting material also requires a certain height, a small step of a few centimeters in height can be provided between the inclined notched part 12 and the nesting trough 11 , which is then later bridged by the bird parents with introduced nesting material.

Fig. 2 shows the nest cavity according to Fig. 1 in Section along the line II-II seen from above. It can be seen that the wall 13 of the nest cavity in the direction is bulged out on the closure 9, so that the aforementioned free movement space is created here, which is beneficial not only for the young birds but also for the bird parents. The bird parents are sitting

not immediately in front of the entrance hole and have the option of lowering the tail that goes into the Most nesting holes have to be carried very steeply. From the entrance gap 6 the path leads diagonally over down the steps 12 to the nesting trough 11.

Numerous substances more or less imitated from nature are known as the material for the nesting holes; it is also convenient to use pumice as a building material.

In the nest cavity according to the invention, a sick, not yet fully fledged young bird, which by its excrement, which is excreted without a covering skin, poses a threat to the other young birds, brought by the bird parents without difficulty over the sloping surface to the flight gap and there be thrown out. If the sick young bird is already bigger, it becomes the attractiveness of the parents follow while feeding until he climbs out of the nest himself. The interior space is beneficial in the illustrated way, so that the bird does not keep the tail upright even when breeding must hold. Enlarging the entrance hole beyond the dimensions of the bird makes it easier acceptance by half-cave breeders and is easily possible with the subject matter of the invention, as the freely swinging suspension is relatively well protected from uninvited visitors at the entrance hole and because the bird that is breeding in the lower part is still far enough away from the entrance hole, to feel safe enough there in the semi-darkness. The nest is also better ventilated.
