BTO Research Reports

BTO Research Reports

BTO Research Reports are scientific papers that have been self-published by the BTO. The following is a full list of the published BTO research reports, which includes BBS reports, Waterbirds in the UK (WeBS) reports and SMP reports. Most are free to download, and links to Abstracts are included where possible.

Numbers missing from the list are those allocated but which were never produced or which have not been published. BTO recognises that, particularly in respect of commercially sensitive cases, a period of confidentiality is appropriate for some projects. However, in the interests of scientific development and dissemination of information, we encourage clients to permit publication as soon as it is reasonable to do so.
