AB We examined interacting effects of habitat structure, topographic landscape, road edge andvehicle traffic (density and noise), on bird species composition, abundance and diversity inthe laurel forest of Tenerife (Canaries). We examined multivariate habitat and landscapefactors determining bird community composition and structure, and modality of specificresponses by comparing road edge vs interior zones. Abundance of breeding birds in laurelforest showed slight to no increases in response to roads. Two specialized taxa, the palaeoendemicpigeon Columba bollii and Regulus regulus, revealed neatest negative reductions inabundance near roads. Higher noise levels, vegetation density, lower canopy closure andwood selective extraction characterized roadsides. Most passerines showed moderate affinityfor forest edges and did not evidence decreases due to road proximity. The topographiclandscape in these mountainous areas strongly interacted with road edge effects to determinebird community structure. Narrow road disturbances on the laurel forest was relatedto moderate increase in bird abundance and diversity near edges, but at the cost of losingpresence of forest-demanding species playing important ecological roles.
