Preventing the Electrocution of Birds

Preventing the Electrocution of Birds

The silent epidemic of bird electrocution 

Bird electrocution at power lines has been documented for over a century, yet the issue persists and the scale of the problem has increased, such that electrocution is now the single most important cause of mortality for a number of endangered species. The impact of electrocution can be especially severe for globally threatened predators and scavengers such as the Saker Falcon, Steppe Eagle, Spanish Imperial Eagle, Egyptian Vulture, White-backed Vulture and Cape Vulture. The Bird Strike Indicator (BSI) is an automated vibration-sensing and recording tool designed to detect bird strikes on aerial cables such as power lines and guy wires. It affordably provides utilities the ability to identify the most dangerous line segments and determine the effectiveness of line marking devices. The BSI uses accelerometers to record stress waves and vibrations caused by a bird strike. The BSI sensors are installed on the monitored wires and transmit strike activity wirelessly to a nearby base station where the data is recorded.
