Open-access The Common Potoo Nyctibius griseus (Nyctibiiformes: Nyctibiidae) in mangroves of the Brazilian Amazon

The Common Potoo, Nyctibius griseus (Gmelin, 1789), is a nocturnal bird widely distributed in South America, primarily in tropical forests and dense vegetation areas. Despite its broad range, its presence in Brazilian coastal mangroves remains poorly documented. We recorded the species in the Amazonian mangroves of the Ajuruteua Peninsula, Bragança, Pará. Observing an adult with a chick confirms that mangrove forests serve as reproductive habitat. This record demonstrates the ecological plasticity of N. griseus and its ability to occupy structurally distinct environments. Our findings highlight the importance of mangrove ecosystems for terrestrial avifauna and underscore the need for further studies on bird biology in understudied Amazonian habitats.
