The dominant context for our scientific work is undertaking impartial research on bird populations in a changing environment, to better inform the management of resources and to aid conservation effort. We are committed to developing and advancing the science of ornithology through the use of innovative analyses and the latest data-gathering technology.

Our approach involves work at a range of scales from extensive volunteer-based monitoring programmes to intensive observations and experiments. While the focus of our research is on British and Irish birds, we are increasingly involved in international work and in collaborative research that includes other taxa.

Much of our research is based on data derived from our long-term monitoring schemes. Our population dynamics and modelling theme is continuing to develop the understanding of demographic processes and their environmental drivers. Climate change is a cross-cutting issue, touching on many aspects of our research, both directly in terms of its impact on the natural environment and indirectly through Government policies designed to mitigate and adapt to the change. Our theme on multi-scale habitats addresses the ecological consequences of land-use and landscape change. Using our expertise to collaborate on international projects is becoming an important priority for the BTO, as is broader inter-disciplinary work. We have a long history of migration research and knowledge about the ecology of migration is important in understanding the mechanisms causing population change in migrant species. Through our wetland and marine theme, we are at the forefront of delivering information on waterbirds in the UK, often in response to the requirements of international legislation and policy development. In recent years we have increased our involvement in seabird research to complement our expertise on waders and wildfowl.

We endeavour to publish much of our scientific work in peer-reviewed journals. To see details of all our recent publications please visit the Publications page.

Where appropriate, we collaborate actively with those who have complementary expertise such as the statutory conservation agencies, universities and other research institutes. We are an Affiliated Institute of the University of East Anglia, a member of the Cambridge Conservation Initiative and we also maintain particularly strong links with the University of Birmingham. Collaborative work with Europe is promoted through our active involvement in EURING (European Union of Ringing) and in the European Bird Census Council. We are always seeking to extend these areas of collaboration.

Might migrants introduce West Nile Virus?

Although not yet found in Britain, West Nile Virus (WNV), which can cause serious illness and even death in humans, has been reported as close as southern France. WNV can be carried by wild birds and Britain falls on major migration routes of birds travelling from countries where WNV is found. This study investigates the possibility that WNV could be introduced to Britain by migratory birds.

Is Willow Warbler breeding changing with the times?

New research by the BTO and the University of East Anglia uses information from the Nest Record Scheme to investigate changes in Willow Warbler breeding between the 1960s and the present day. Despite advances in the timing of egg laying, there has been little change in Willow Warbler productivity over this period.

Are Tree Pipit and Lesser Redpoll declines linked to changes in young woodland?

New research examining the relationship between the availability of young woodland and two declining species - the Tree Pipit and the Lesser Redpoll - indicates that while important, young woodland availability is not the primary driver of population trends in these species.
