Author: H.T. Harvey & AssociatesPublication: American Wind and Wildlife InstituteYear Published: 2018 Bird collisions with anthropogenic objects are well documented in the literature, including those involving wind turbines. The purpose of this study was to evaluate and help improve the effectiveness of an automated detection and deterrent system designed to minimize the risk of raptors…

Wind Harvest’s VAWT-Bird Collision Calculator

Author: Matthew WylderPublication: Wind Harvest InternationalYear Published: 2014 WHI commissioned UCD engineer Matt Wylder to take the Scottish Natural Heritage model for calculating bird strikes in HAWTs and redo it for VAWTs. His paper “Vertical Axis Wind Turbines and Birds: Calculating a Theoretical Collision Risk Assuming No Avoiding Action” summarizes a number of runs he…

Calculating a Theoretical Collision Risk Assuming no Avoiding Actions

Publication: Scottish Natural HeritageYear Published: 2000 Windfarms may impact on ornithological interests in a number of ways. There may be: loss of habitat due to the construction of turbine bases and tracks, displacement of birds as a result of disturbance, and potential mortality through collision. SNH Guidance note describes a methodology for assessing in full…

Impacts of Wind Farms on Birds: A Review

Author: Ralph PowleslandPublication: Science For Conservation 289Year Published: 2009 The impacts of wind farms on New Zealand bird species and populations are unknown. This document reviews available literature on the impacts of on shore wind farms on birds, based on studies in other countries. A key finding is that wind farms tend to have variable effects on bird…
