Dickcissels exhibited a complex interaction between turbine and grass height: in the presence of turbines they were denser in tall grasses, which coincided with increasing distance, but in the absence of turbines they were distributed uniformly. In contrast, the density of Eastern Meadowlarks ...
also occur during the day. Factors such as topography, turbine lighting, turbine height, the presence of guy wires, weather, and numbers of birds moving through an area on migration can influence the number of migrant collisions observed at a facility. ...

Inform students that they will be working in groups to build wind turbine models, and testing the effects of using different sized blades on each model. Review with students the basic parts of a wind turbine: base (or tower), axle (or shaft) and rotor with the blades and hub. How do ...
The movement of wind-turbine blades creates a vortex of lower air pressure around the blade tips similar to the vortex at the tip of aeroplane wings. Others have suggested that this could be lethal to bats, but until now no-one had carried out necropsies to verify the theory. ...
Some critics raise concerns about the visual impact of wind farms on landscapes and the potential effects on wildlife, particularly birds and bats. Addressing these concerns requires careful planning and technological innovations, such as the development of bird-friendly turbine designs and strategic ...
Several methods are used to study the behaviour of birds of prey in relation to wind farms, including telemetry data, field observations, and comparisons of turbine base areas. Special attention is given to the effects on different bird species and the impact wind farms may have on population ...
casualties as a result of collisions with rotating rotor blades for a wind farm of 1000 MW represent only a very small fraction of birds killed from hunting, high-voltage lines, and traffic; the estimates predict a maximum level of six to seven bird collisions/turbine/year (see Table II)....
In light of wind turbine rotor diameter approaching 300 m, the question arises, if there are any limitations on the size of the offshore wind turbines, and what implications this might have on the design of the associated floating platforms. A number of studies have attempted to investigate ...
Wind farms generate lots of energy, but they cause several side effects, such as noise and a threat to wildlife. It is reported that the bird collision rate of a wind turbine ranges from 0.01 to 23 annually. It is more serious in the case of rare and endangered birds. In order to ...
