Infanticide by the White-throated Cacholote (Pseudoseisura gutturalis) in the Monte Desert, Argentina

Abstract

We documented a case of nonparental infanticide at a nest of White-throated Cacholote (Pseudoseisura gutturalis) in 2018 in xeric northwestern Argentina, the first confirmed for the large family Furnariidae. Competition for resources such as food or nest sites, rather than cannibalism or short-term mating opportunities, may underlie this event.
