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. 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.

The State of UK’s Birds reports have provided an periodic overview of the status of the UK’s breeding and non-breeding bird species in the UK and its Overseas Territories since 1999. This year’s report highlights the continuing poor fortunes of the UK’s woodland birds, and the huge efforts of BTO volunteers who collect data.

The acoustic identification of small terrestrial mammals in Britain
Author: Newson, S.E., Middleton, N. & Pearce, H.
Published: 2020
Britain is home to several species of small mammals, which include rats, mice, voles, dormice and shrews. All of these are difficult to observe in the wild, and it is usually necessary to capture them to confirm their presence. By describing the vocal repertoire of small mammals in Britain, research published in British Wildlife by a team led by the BTO provides new possibilities for sound identification to be used as a non-invasive survey method.

Published: 2020
A newly published assessment of the evidence that climate change is causing biodiversity populations to decline as a result of divergent changes in the timing of consumer demands and the availability of species that they feed on, highlights significant evidence gaps.
