Blue-winged parrotlet Forpus xanthopterygius (Aves: Psittacidae), feeding over water in Southeast Brazil

The blue-winged parrot Forpus xanthopterygius is widely distributed in South America, where it lives in groups in different types of environments and feeds on fruits, seeds, flowers and nectar. In 2023 we observed a group of these birds moving from a forested area to an area of aquatic vegetation on the bank of a water reservoir in Southeast Brazil. The birds landed among the leaves of a cluster of Polygonum ferrugineum, approximately 45 cm above the water surface, and consumed flower buds and flowers — a plant species not yet reported for their diet. This behavior occurred during the driest period of the year (April), and may represent an alternative diet due to the scarcity of the preferred resources of this bird species during this period. The species is known to use habitats associated with water and to feed at low heights or even on the ground. However, this behavior of searching for resources on aquatic vegetation at the water surface in the middle of an urban reservoir has not been described and shows the adaptability of these birds to human environments and their high capacity to find food in the most varied types of habitats.
