bird species which interacts with powerlines

Mortality of birds on power lines through collisions and electrocutions, in particular to large birds of prey, bustards, cranes, storks and flamingos is a threat of unknown extent. These wildlife-power line interactions may also cause blackouts, resulting in high maintenance and repair costs. Smaller birds including Sociable Weavers, Red-billed Buffalo-weavers and crows use power line structures for roosting and nesting and are a further source of wildlife-related faulting. Bird interactions with power lines include: Collisions with power lines; Electrocutions on electricity infrastructure; Breeding activity on power lines causing short circuits; Bird droppings causing flashovers; Destruction of sensitive bird habitat caused by the construction of new power lines.
