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.

This report presents the main findings from survey work delivered using passive acoustic monitoring devices deployed across the Bailiwick of Guernsey. Through the surveys that we support we aim to improve knowledge and understanding of species distribution and activity, covering a range of taxonomic groups, including bats, small terrestrial mammals and insects. Through this approach we provide robust datasets that can be used to inform better decision-making processes.

Declines in invertebrates and birds – could they be linked by climate change?
Author: Pearce-Higgins, J.W. & Morris, R.K.A.
Published: 2023
The long-term declines evident in many bird and invertebrate species have their origins within a suite of potential drivers, one of which is climate change. As well as impacting bird species directly, could climate change be increasingly hitting bird populations through its impacts on their invertebrate prey?
