Resumen
Las aves marinas son uno de los grupos de aves más amenazados a nivel global. Sin embargo, varias actividades humanas también proveen recursos que estas aves pueden utilizar en su beneficio. Se presenta una síntesis del conocimiento sobre el uso de recursos antrópicos por parte de las aves marinas que se reproducen en el litoral patagónico argentino. Las investigaciones realizadas indican que un total de quince especies utilizan recursos antrópicos para su alimentación y/o nidificación durante los meses de la temporada reproductiva. De los diferentes recursos de alimento de origen antrópico identificados, el provisto por la pesca comercial durante las operaciones en el mar es utilizado por el mayor número de especies (doce) y el que representa la oferta de mayor extensión geográfica. Un menor número de especies hacen uso de residuos urbanos (cuatro) y de recursos derivados de la pesca recreativa (tres) y la actividad agrícola-ganadera (seis). En relación a los recursos antrópicos para nidificar, la información disponible es mayormente anecdótica, e indica que seis especies aprovechan ambientes y/o estructuras antrópicas para construir sus nidos, y siete incorporan materiales antrópicos en los mismos. Se discuten los posibles beneficios y costos asociados a dicho uso, y se consideran los posibles conflictos derivados en relación a otras especies y las poblaciones humanas. Se espera que esta síntesis de conocimiento, identificando limitaciones de estudios previos y vacíos de información, contribuya a la definición de prioridades de investigación y al desarrollo de recomendaciones para el monitoreo de las interacciones entre aves marinas reproductoras y actividades humanas.
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.
