Climate change disrupts species’ populations worldwide
Newly published research led by the BTO shows a consistent impact of climate change on biodiversity around the world.
Range expansion as a short-term consequence of climate change
New BTO research has used data from the Breeding Bird Survey to show that many of our birds have expanded their geographic range as a short-term response to climate change.
British Woodcock show declines in breeding population size and range
Results from the 2013 Woodcock Survey show that breeding numbers and breeding range have both declined considerably since the previous survey in 2003. The rate of decline varied regionally but was least pronounced in areas that contained large tracts of continuous woodland.
Garden bird feeding and a changing climate are driving evolutionary change in Blackcaps
New research using data from Garden BirdWatch has revealed that bird food provided in British gardens has helped Blackcaps to rapidly evolve a successful new migration route. This is the first time that garden bird feeding has been shown to affect large-scale bird distributions.
When does a changing climate impact on bird populations?
Climate change impacts are well-known but what are the drivers that bring about the changes we are seeing in our bird populations?
