Use of anthropogenic resources by seabirds breeding in Argentine Patagonia

Abstract

Seabirds are one of the most threatened groups of birds globally. However, several human activities also provide resources that these birds can use for their benefit. We present a synthesis of knowledge on the use of anthropogenic resources by seabirds breeding in the Argentine Patagonian coast. Research indicates that fifteen species use anthropic resources during the months of the breeding season. Of the different food resources of anthropogenic origin identified, the one provided by commercial fishing during operations at sea is used by the largest number of species (twelve) and the one that represents the most geographically widespread offer. A smaller number of species make use of urban waste (four) and resources derived from recreational fishing (tree) and agricultural-livestock activity (six). In relation to anthropic resources used for nesting, the available information is mostly anecdotal, and indicates that six species take advantage of anthropic environments and/or structures to build their nests, and seven incorporate anthropic materials in their nests. We discuss the potential benefits and costs associated with such use, and consider the potential conflicts with other species and human populations. We expect that this synthesis of knowledge, identifying limitations of previous studies and information gaps, will contribute to the definition of research priorities and the development of recommendations for monitoring interactions between breeding seabirds and human activities.
