Wildlife-Road Interactions and Conservation

On this paper new bird registers are provided on the Quilmes and Avellaneda (Buenos Aires province, Argentina) district?s river coast. The studied region includes two preserved areas: Municipal Natural Reserve Los Sauces and Natural Park and Municipal Ecologic Reserve Selva Marginal Quilmeña, as well as uncategorized conservation sectors, covering, as a whole, more than 300 hectares. Observations were made by the Bernal?s Bird Observers Club, as well as by students from Facultad de Ciencias Naturales y Museo (Universidad Nacional de La Plata). 31 new species were added in comparison to old papers, belonging to the families Tinamidae (1), Falconidae (1), Anatidae (2), Ardeidae (1), Rallidae (3), Strigidae (2), Cuculidae (1), Alcedinidae (1), Furnariidae (7), Sturnidae (1), Motacillidae (1), Thraupidae (2), Tityridae (5), Icteridae (2). Registers on Spartonoica maluroides (Bay-capped Wren-spinetail) and Asthenes hudsoni (Hudson's Canastero) stand out, both of them labeled as vulnerable, besides several other species classified as scarce and sensitive to anthropogenic disturbances. A single specimen of Icterus croconotus (Orange-backed Troupial), a native species from Chaco Húmedo (Wet Chaco) ecoregion, was spotted too. It is noteworthy to point out the recording of Acridotheres cristatellus (Crested Myna), a bird that was introduced in our country and whose impact on native birds and other animal species is unknown. With this contribution, registers with conservationist value were added, and the number of observable species rises from 124 to 155 for this area, which is under an important antropic impact, and it is considered a possible ecological corridor between Punta Lara and Costanera Sur natural reserves.
