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.

Spatial distribution and habitat preferences of the House Sparrow, Passer domesticus in urbanised landscapes

Author: Shaw, L.M., Chamberlain, D., Conway, G.J. & Toms, M.P.

Published: 2011

The House Sparrow Passer domesticus has declined in urban areas across Europe since the late 1970s and is now listed as a species of conservation concern. Recent research into the causes of decline suggests that breeding populations may be influenced by a number of urban habitat features. These include pollution levels, insect abundance, nest site availability and the presence of predators. In this Research Report, we examine how the presence of certain features within the urban environment relates to the location of House Sparrow colonies.
