Resumen
La presencia de perros no supervisados en áreas urbanas próximas a sitios de alto valor natural puede tener efecto negativo sobre la fauna silvestre. En la costa patagónica, donde las ciudades suelen estar rodeadas de ambientes naturales, esta problemática puede afectar a colonias de aves marinas. Dos islas con colonias de Pingüinos de Magallanes (Spheniscus magellanicus) pertenecientes a un área protegida vecina a Puerto Deseado, Santa Cruz, sufrieron ataques de perros no supervisados. En 2016 y 2022, varios perros cruzaron a estas islas durante bajamares y atacaron pingüinos. En la isla Quiroga murieron 421 pingüinos en 2016, causando una disminución del 21.4% de su población. En la isla Quinta murieron 30 individuos en 2016 y 32 en 2022, correspondiendo en ambos casos a casi el 100% de la colonia. Estos son los primeros registros de ataques desde que monitoreamos estas colonias (> 30 años). El crecimiento de las ciudades costeras es constante y estos eventos podrían volverse más frecuentes y afectar a más especies de aves marinas. El control de los perros no supervisados en áreas naturales cercanas a urbanizaciones costeras es un desafío que los entes gubernamentales deberían asumir en el corto plazo.
The presence of unsupervised dogs in urban areas close to sites of high natural value can have negative effects on wildlife. On the Patagonian coast, where cities are often surrounded by natural environments, this problem may affect seabird colonies. Two islands with Magellanic Penguin (Spheniscus magellanicus) colonies belonging to a protected area neighboring Puerto Deseado, Santa Cruz, suffered attacks by unsupervised dogs. In 2016 and 2022, several dogs reached these islands during low tides and attacked penguins. At Isla Quiroga, 421 penguins died in 2016, causing a decrease of 21.4% in its population. At Isla Quinta, 30 individuals died in 2016 and 32 in 2022, representing in both cases almost 100% of the colony. These are the first records of attacks since we are monitoring these colonies (>30 years). The growth of coastal cities is constant and these events could become more frequent and affect more species of seabirds. The control of unsupervised dogs in natural areas near coastal developments is a challenge that government entities should respond to in the short term.
