A key component of post construction monitoring at windfarms is assessing the levels of bird and bat collisions. At Eire Ecology we specialise in this field and are keen to offer these services to you.
Carcass searches were traditionally completed by human observers whose efficiency is influenced by a number of factors including; carcass type (size, color, state of decomposition), environmental conditions (vegetation type and density, topography, weather conditions) and observer competence (ability to detect). Reviews of previous studies state human searches are often conducted with low efficiency rates which may contributes to severe bias in mortality estimates. The use of dogs and their olfactory capabilities has been suggested as a way to increase carcass detection rates (Bernardino et al; 2012).
Numerous studies have been conducted demonstrating that dogs have a superior ability to detect bird and bat carcasses than humans, particularly with small carcasses or in dense vegetation (Homan et al. 2001; Arnett 2006; Paula et al. 2011; Reed et al. 2011; Mathews et al. 2013).
