<p>A bird-feeding station (KE) has a carrying rod (1) fitted out with an eccentric vertical hole, a co-axial hole through a spring (3), which is, together with slat (2), glued onto rod (1), a movable longitudinal weight (7) on the shorter (left) end, and a feeding unit (6) on the longer (right) end, and is suspended from a fixing wedge with a knitted steel wire (4). The position of rod (1) on the knitted steel wire (4) with a weight, which keeps the knitted steel wire strung out, is determined by the position of support clip (8). Weight (7) on the transverse rod (1) and spring (3) enable an immediate re-establishment of balance and horizontal position of the rod (1). Such a bird-feeding station can solve the problem of supplying only certain bird species with food, may be inaccessible to cats and other predators, and can reduce the possibility of transference of parasites from one bird to another. <IMAGE></p> |
