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.
