The BOU supports students studying ornithology including their attendance at conferences, including this first EOU meeting in the UK. The BOU also runs a Career Development Bursary scheme for early career reasearchers and awards Small Ornithological Research Grants annually to projects around the world. British Trust for Ornithology www.bto.org The BTO is a scientific research organisation specialising in birds and their habitats. We undertake impartial research and analysis to advance the understanding of natural systems. The BTO provides high quality, impartial and policy-relevant data and information, relied upon for informed decision making. We work in partnership with the academic and conservation science communities, Government, and the private and voluntary sectors. Edward Grey Institute of Field Ornithology www.zoo.ox.ac.uk/egi The Edward Grey Institute of Field Ornithology (EGI) is part of the Department of Zoology of the University of Oxford. Founded in 1937, it researches the behaviour, ecology, evolution and conservation of birds, emphasizing the need to understand organisms in their natural environments. The EGI is well known for its groundbreaking population studies of birds, and was a founding supporter of EOU. RSPB www.rspb.org.uk The RSPB speaks out for birds and wildlife, tackling the problems that threaten our environment. We are the largest wildlife conservation organisation in Europe, with over a million members.

Therefore, despite recent economical downturns and hardships, funding cuts, and other obstacles affecting many people in Europe, ornithologists manage to do fairly well. This is clearly demonstrated by a large number of attending delegates, coming from every corner of Europe and beyond, as well as by a diverse set of scientific presentations. Like their highly mobile study subjects, many ornithologists have recently become wanderers, often having worked in several different countries by the mid-point of their careers, producing great benefits in terms of the cross-fertilization of ideas and practices. The second visible and very positive current tendency is a growing number of international teams carrying out continent-wide collaborative studies. The promotion of such interactions in Europe is the role of the EOU and conferences are the most important means by which it achieves its objectives. This abstract book, containing a rich and varied set of talks and posters, shows that the Norwich conference will certainly fulfil that purpose. For that we have to thank not only the speakers and the authors of the posters, but the symposium organisers and the Scientific Programme Committee (under the chairmanship of Nikita Chernetsov), who have solicited contributions from all over Europe and drawn them together into an exciting programme. The EOU, without staff and almost without financial resources, depends on the voluntary efforts of many people. Conferences depend on the hard work of the organising team in the host country and our UK hosts have done us proud. They have provided excellent arrangements. This will allow us to get the most out of both the programme and the informal part of the conference – discussions and making new contacts are such an important part of our meetings. A significant part of the organisation of this conference has been to provide modest financial support for young ornithologists and for those from lower income countries, to help them to participate in the meeting. In addition to the contribution from the EOU, the British Ornithologists' Union has funded the attendance of 45 student and early-career researchers and the BOU and Swarovski are sponsoring prizes for the best student oral and poster presentations. Continuity and communication between conferences depends on the EOU’s Council. A new team of officers and Council members is to be elected at the General Meeting on Thursday, to which all conference participants are invited. Please give the EOU and their officers your support, share with them ideas about how the work of the Union may be developed, so that European ornithology continues to flourish and to grow in strength and effectiveness. Welcome to Norwich and to EOU 2013! Enjoy the conference!
