In Russia, many birds die due to electrocution caused by power lines. Uninsulated parts, such as wires and contacts, and grounded support posts and crossarms are easily accessible to birds. If the bird touches both the grounding element and the wire, it completes the circuit, which gives bird an electric shock, usually fatal. The distance between the wire and the corner of the grounded crossarm is 15-25 cm, which is roughly the body size of a small bird. It is less common for birds to close a circuit between wires, since the gap between the phases is much larger, but this is nonetheless dangerous for large species of birds.
Power lines are an integral part of the industrial landscape of the Central Non-Black Earth Region. In the north of the Moscow Region, where the “Crane Land” system of specially protected natural areas is located, there is a developed network of power lines with various characteristics. Before 2015-2017, when the bird diverters were installed and the bare wires were replaced with self-supporting insulated wires, the death of birds from electric shock was often there. Moreover, there are a number of negative factors that cause the death of birds, and so this article is the first one to summarize those causes.
Keywords: birds and power lines, bird diverters, self-supporting insulated wires, industrial landscape.
