BTO's international research cuts across many of the organisation's research themes and has a broad remit, taking in classical ecological studies, as well as incorporating elements from the social and economic sciences. We operate in three broad areas – research into the ecology of long-distance migrant birds, provision of technology transfer and capacity building and research into the links between biodiversity, the natural environment and people in developing African countries.

Curlews and godwits - the vanishing tribe

New collaborative research led by the BTO investigates reasons for recent losses in curlews and godwits worldwide and identifies conservation measures which could be put in place to halt the declines.

Cuckoo declines linked to different migration routes to Africa

When the BTO began ground-breaking Cuckoo tracking research in 2011, we had very little idea where these birds spent the winter or how they got there. Our latest research not only reveals this information, but also shows that Cuckoos’ use of autumn migration routes helps explain population declines.

Protected areas help rare duck adapt to climate change

Data from the Wetland Bird Survey have contributed to new research showing how Europe's winter population of Smew has redistributed north-eastwards due to milder winter conditions in the last 25 years. The study, involving scientists in 16 countries, also demonstrated that population growth has been twice as fast inside protected areas compared to outside.
