Consequences for birdlife of installation of smaller wind turbines. Konsekvenser for fuglelivet ved etableringen af mindre vindmoeller

Technical Report:

Abstract

Wind turbine arrays are often placed in open coastal areas which may well be important breeding of gathering localities for a number of bird species. Nine windmill parks (55-99kW) in Denmark have been observed for a period of 15-18 hours (for each park). Local birds appear to habituate to the windmills, and migrating wildfowl, especially swans and geese often change their course at a long distance from the sites. Waders, however do not react until they come close and often react violently, yet only two birds, out of 1939 passing flocks, have been recorded as killed during the period of observation. It was concluded that if windmills are placed in a line at small intervals across a migration route they may present a serious problem to wildfowl and cormorants, for example. The problem is greater where wind turbine arrays have been placed at locations being used as feeding grounds by the birds. It was observed that some species had restricted their feeding areas. It is concluded that windmills present a minor threat to migrating birds compared to radio towers. It is recommended that migration routes and gathering areas of sensitive species, primarily wildfowl and waders, should be avoided as sites  More>>
