We have worked on the avian impacts of numerous transmission and power distribution lines.

These studies have had two foci. First, the impact of lines and towers directly upon birds via collision and the impact of siting of lines on critical habitats. In the first case of collision, studies typically focus on the impact that line-induced mortality may have on the viability of threatened and endangered species populations.

In the second case of habitat, studies focus on how a new transmission line or the expansion of transmission lines would impact critical habitats located in the proposed transmission corridor. For the latter, habitat studies often include the need to ground-truth GIS maps showing the habitats that would be impacted by transmission.
