Environmental Research Database

SummaryBTO Winter Gull Roost Survey (WinGS): 2004/07. To assess the significance of Northern Ireland gull populations Background The BTO has organised national surveys of winter gull roosts each decade since 1953 in order to estimate numbers of wintering gulls. The last survey took place in January 1993, during which over 2.5 million gulls were counted in Great Britain. A further 19,000 gulls were also counted in Northern Ireland, 3,850 in the Isle of Man and 8,500 in the Channel Islands. (The re [continued...

The effect of the Sep wind park near Oosterbierum, Friesland, The Netherlands, on birds. De invloed van de Sep-proefwindcentrale te Oosterbierum (Friesland) op vogels; Deel 3: Aanvlieggedrag overdag  

Energy Technology Data Exchange (ETDEWEB)

The study concerns 1984-1991. The wind park consists of 18 three-bladed 300 kW horizontal axis wind turbines of 35 meters height, and a rotor diameter of 30 meters, seven meteorological towers, and three cluster and control buildings. Aspects studied included disturbance of breeding, resting or feeding, and migrating birds, behavior of birds approaching the wind turbines during the day and night, and bird victims due to collision with the wind turbines and the meteorological towers. The flight behavior of birds approaching the wind park system during daylight is also dealt with. For at least a fifth of the observations it was noted whether the birds passing within 100 meters distance of a turbine showed a reaction or not. The proportion of the reactions was related to the wind park in operation or not in operation, and to the distance between the wind turbines, species, flight height, the passing distance, wind direction and wind force. Secondly the flight path of birds approaching the ...
