BTO Research Report No. 252.
BTO, Thetford.

This report is a "one-stop-shop" for information about the population status of our common terrestrial birds. With one page per species, readers can quickly find all the key information about trends in population size and breeding performance as measured by BTO monitoring schemes. It provides an overview of trends for the period 1966-1999.
The report covers over a 100 breeding bird species but excludes colonial seabirds and relatively rare species, which are already well covered by other schemes.
For each species, we provide: 
  General information on a species' conservation listings (to show the level of concern about the species);
  A brief summary of its population changes and information about the possible causes of population changes;
  A series of graphs and tables to show the trends and changes in population size and breeding performance over the past 30 years.
New for this report are:
  Trends from the BTO/JNCC/RSPB Breeding Bird Survey (BBS), not only for the UK but also for each of its constituent countries (England, Scotland, Wales and Northern Ireland);
  A new system of Alerts that highlight where population declines of greater than 25% or greater than 50% have occurred over the past 5 years, 10 years, 25 years and 30 years.

This report is the third in a series, prepared within the Partnership between the British Trust for Ornithology (BTO) and the Joint Nature Conservation Committee (JNCC) (on behalf of Natural England, Scottish Natural Heritage, Countryside Council for Wales and the Environment & Heritage Service of Northern Ireland) as part of its programme of research into nature conservation.

It is the result of the sustained long-term fieldwork efforts of many thousands of the BTO's volunteer supporters. Without their enthusiasm for collecting these hard-won facts, the cause of conservation in the UK would be very much the poorer.

The BTO is grateful to Mr and Mrs J A Pye's Charitable Settlement, which provided additional support towards the development of the website. We are also very grateful to Susan Waghorn who has put in a huge amount of skill and effort in designing and putting together the website for this report.

We are particularly grateful to Malcolm Vincent (JNCC) for his helpful discussions, comments and support during the production of the report. We would also like to thank the following for helpful discussions on previous editions of this report: David Stroud, Rowena Langston, David Gibbons, Jacquie Clark, Nigel Clark and Jeremy Greenwood. Analyses of ringing data would not have been possible without the hard work of members of the Ringing Unit at the BTO HQ in Thetford: Jacquie Clark, Sue Adams, David Anning, Jez Blackburn, Bridget Griffin, Jackie King, Linda Milne, Brenda Read, Anne Trewhitt, Angie Whybrow.
