Bird and bat species' global vulnerability to collision mortality with wind farms revealed through a trait-based assessment.

In a changing world, the development of green energy is more important than ever. One of the most well-developed and cheaply available options is wind power, but there is evidence that wind farms can also have a negative impact on biodiversity. This 2017 study, funded by the Cambridge Conservation Initiative and led by BTO, is the first to look at the global impact of wind farms on bird and bat populations.

Environmental correlates of breeding abundance and population change of Eurasian Curlew Numenius arquata in Britain

Wader populations are declining worldwide, with causes often being linked to the loss and degradation of habitats, increased predation, and a changing climate. Here in the UK, we have seen dramatic declines in Curlew populations over recent decades, resulting in the species being proposed as the UK’s most important bird conservation priority. If we are to halt and reverse these declines then we first need to understand which threats this iconic species is facing.

The risk of extinction for birds in Great Britain

The UK has lost seven species of breeding birds in the last 200 years. Conservation efforts to prevent this from happening to other species, both in the UK and around the world, are guided by species’ priorities lists, which are often informed by data on range, population size and the degree of decline or increase in numbers. These are the sorts of data that BTO collects through its core surveys.

Flight Lines: Tracking the wonders of bird migration

This stunning new book brings together the latest research findings, delivered through an accessible and engaging narrative by the BTO's Mike Toms, with the wonderful artwork generated through the BTO/SWLA Flight Lines project. If you have an interest in our summer migrants, then you'll welcome this fantastic opportunity to discover their stories through art and the written word.
