The authors analyse the use that birds are doing of the new habitats associated to the construction of this motorway. They have focused their analysis in the evaluation of bird's composition variation on slopes and, also, in the spatial distribution of the species observed. Also temporal evolution and comparison between cuttings and embankments are analysed.  Big differences are remarked in the evolution for each slope and the bird's population difference in the surrounding's forest. The authors have noticed that the slopes constitute an habitat very differentiate of the surrounding, with a new trophic offer for the granivora species. Presence of big trees in the slopes constitutes an important element that facilitates the entrance of insectivora species form the surroundings. The slopes, moreover are used for wintering individuals, robins mainly, that found new resources to exploit.\n\nEl art\u00edculo es resultado de una experiencia llevada a cabo en el autov\u00eda de Vallvidrera entre 1990 - 1993.

En el estudio se pusieron de manifiesto grandes diferencias entre la evoluci\u00f3n seguida por cada uno de estos taludes as\u00ed como con las poblaciones existentes en los entornos forestales no alterados.
