To provide a cable cover preventing birds from perching thereon to turn away birds trying to perch on cables at bus terminals, subway exits, shopping districts, etc., because birds including starlings have a habit of flocking together on cables, street trees, etc., to make beds for the flock to sleep together during the autumn or winter, thus often bothering people with droppings and noises.

A bird-turning-away cable cover 1 composed of two semi-cylinders connected at their one sides is easily set on an existing cable. The cable cover 1 is light in weight, and is provided with a slide ring 3 to be able to turn easily. The cable cover 1 thus has an effect of turning away birds that is sure and lasts longer. Because the cable cover 1 is molded with a synthetic resin, the cable cover 1 can be mass produced in a short period at low cost.
