Field observations reveal new predation and kleptoparasitism by Andean Gull in endangered vertebrates, suggesting ecological implications.
We record two new predation events and one new kleptoparasitic Andean Gull (Chroicocephalus serranus) behavior, interactions that directly link to the Titicaca Grebe (Rollandia microptera) and Titicaca Water Frog (Telmatobius culeus). Our reports expand the understanding of the gull's ecological niche and reveal previously overlooked interactions between it and two endemic and endangered Lake Titicaca species which act as indicators of Lake Titicaca's ecosystem health.
