Use of natural and anthropogenic resources by Olrog's Gull Larus atlanticus: Implications for the conservation of the species in non-breeding habitats

We studied the exploitation of crab-beds and fishing grounds by Olrog's Gulls Larus atlanticus in non-breeding areas along the coast of Buenos Aires province, Argentina. During 2004 and 2005, censuses were performed in different areas of Mar Chiquita coastal lagoon and Mar del Plata harbour. Ad...
