Assessing offshore wind farm impact assessments for breeding seabirds

As the number of offshore wind farms increases, it is important to correctly assess the impact that these developments can have on wildlife. New research led by the BTO examines this situation for seabirds, considering the current environmental impact assessment process in light of the key factors that determine seabird population dynamics.

Too wet to nest?

Data gathered by nest recorders helps us understand why some nests are successful and others are not. Recent BTO research has developed a method to analyse nest record data more effectively, and revealed some intriguing differences in the effect of rainfall on Blackbird nest success.

Why are Willow Warblers decreasing in the south, but not the north?

New research involving the BTO suggests that Willow Warbler population declines in southern Britain might be reversed by improving productivity there.

GPS tracks and cutting edge stats shed new light on seabird flight heights

New research led by the BTO has used a combination of GPS-tracking and advanced statistics to provide new insights into seabird flight heights by night and day. This study gives important information on the risk of seabirds colliding with offshore wind turbines and at a time when governments worldwide are investing in offshore wind farms.
