ABOUT

I I

The invention relates to ornithology, in particular, to artificial nests for open-nesting dendrophilous birds, and can be used in forestry to attract birds, as well as in research works in studying the ecology and biology of birds,

The purpose of the invention is to increase the efficiency of the population of the expansion of the species diversity of the inhabited birds by imitating the natural conditions that favor the manifestation of the behavioral reactions of the nesting birds.

The drawing shows artificial nesting sites for open-nesting dendrophilous birds.

An example. A support tree 1 is selected with a vertical U-shaped fork 2 of a trunk or a large branch located near a growing conifer tree 3, such as spruce. As a supporting tree 1, a growing tree is used, or in its absence (rare forest, single trees) cut down, for example, when cutting, the trunk or pole fixed them in the ground near the growing conifer tree 2. A densely branched branch of 4 s branches is selected in the crown 3 The second order is 5, growing just above or at the level of fork 2 and laying it at the base 6 of the fork 2 at an angle to its plane. Then choose the second branch 7 from the next tier and with the help of a tie 8 from twine or flexible harness worn her to the first slow 4, while branches 4 and 7 are oriented parallel to each other at a distance of 10-12 cm between them, with the ends of branches 4 and 7 being protruding beyond the plane of the fork 2 with a downward slope. To reinforce the nest structures, part of the secondary shoots 5 of the upper 7 and lower 4 branches on both sides of the fork are connected to each other, forming vertical supports

(not shown). Thus, in the plane of fork 2, a loose nesting chamber 9 is formed, which is sufficiently well masked and provides conditions that favor the development of behavioral reactions of open nesting dendrophilous birds (finch, swirling, glut, shadoputy, etc.). The height of the nest device is selected by taking into account the specific height ranges of nest placement, in accordance with the nest building requirements for masking and the habitat of the birds attracted.

Claims (1)

The invention of the method of constructing an artificial nest for open nests of dendrophilous birds, including placing a branch of a growing coniferous tree at the base of a fork of the support element, pushing and joining the above branch with the formation of the nest chamber between said branches fork of the support element, which is used as a pole fixed in the ground near the said coniferous tree, characterized in that, in order to increase the efficiency of colonization and expansion of the species diversity of inhabited birds by imitating natural conditions, favoring the development of behavioral reactions of the nests of birds, as well as increasing durability at the same time, the vertex parts of both branches are oriented unidirectionally with a slope to the base of the support element.
