Abstract
As wind farms have been developed in Japan, concern has been growing for their impacts on birds. There are three types of impacts: wind turbine collisions, habitat abandonment and barrier effects. During the period from April 2001 to March 2014, 341 bird carcasses were recovered at wind turbines in Japan. Many of them were Black Kites, White-tailed Eagles, gulls and crows. Habitat abandonment was reported from Kyoto and Mie Prefectures, where bird population density decreased around the wind turbines. Barrier effects were reported from Ehime Prefecture
for Honey Buzzards and for Hooded and White-naped Cranes from Nagasaki Prefecture. These species changed their flight paths to avoid wind turbines. The continuous monitoring of birds in wind farms is needed to study the effects of wind turbines on birds.
