ABSTRACT
The impact of electric energy transfers from power plants generation to substations then to consumers and its own environment is tremendous. Among various hazards, the overhead wires associated with power lines are the most fatal hazard to birds. The power lines and poles have caused fatal risks for birds and have affected their habitats significantly. Dangerous types of power poles in the middle voltage lines which have small distances between the lines and short insulators cause short-circuits between conductor wires or ground-faults. This paper presents a survey conducted in Multan city, Pakistan. In this survey, all 132kV high voltage grids and their 11kV outgoing feeders are observed and their locations are also marked on Google map. This survey includes current construction type of power lines and poles, principles for bird safety, photographic records, public views about deadly poles and Ultraviolet vision in Birds. This study also highlights the cause of bird casualties on high and large scale from overhead power lines. It presents different technical solutions for bird safety such as proper adjustments to the routing of the power lines and power pole constructions can effectively reduce the risks posed to birds. Detailed study is recommended on large scale; so that conservation measures can be suggested for reduction of losses on birds by power stations in Pakistan.
