BTO publishes various reports, from those covering the annual results of core surveys, through scientific studies, and on to those produced in partnership with other organisations. Many of these are published as BTO Research Reports. You can access all of our reports from here, though note that we are currently updating the reports section, working backwards through time to bring all of the report pages into a consistent format. You can read our Annual Report and Accounts in the Governance section.

Multi-species spatially-explicit indicators reveal spatially structured trends in bird communities
Author: Massimino, D., Johnston, A., Noble, D.G. & Pearce-Higgins, J.W.
Published: 2015
The BTO/RSPB/JNCC Breeding Bird Survey is the primary source of information about changes in national populations of over 100 bird species. Here we describe analyses of this dataset which has identified important spatial variation in population indicators, highlighting previously unreported declines in habitat specialists in southern and eastern Britain.

The avoidance rates of collision between birds and offshore turbines
Author: Cook, A.S.C.P., Humphreys, E.M., Masden, E.A., Band, W. & Burton, N.H.K.
Published: 2014
Report of work carried out by the British Trust for Ornithology in collaboration with the Environmental Research Institute on behalf of the Marine Scotland Science.Accurately estimating birds’ risk of collision with offshore wind turbines is a key part of the decision-making process for proposed renewable developments. However, the evidence base for quantifying the number of birds likely to avoid colliding with turbines is limited. Recent BTO-led work helping to fill this gap, improving the understanding of the impacts of offshore renewables on marine wildlife.
