<p>The yellow-faced parrot (<i>Alipiopsitta xanthops</i>) is a “Near Threatened” species endemic to the Cerrado. This study aimed to examine its diet in the Brazilian Cerrado through citizen science data, and compare our results with a compilation of food items found in the literature. Searches for photographic records of with evidence of feeding activities were done in the WikiAves platform. A total of 172 feeding records were obtained by citizen scientists in 68 municipalities located mainly in central, southeastern and southwestern Cerrado. Most feeding records showed parrots feeding on fruit, floral resources and vegetative parts of native and exotic plant species. Families, genera and species of plants whose fruits were consumed by these parrots were more numerous than those of consumed floral resources. Feeding records involving the consumption of fruit were more numerous than those with floral resources; this was valid for both the native and exotic plant species. The most frequent plant species in the diet of yellow-faced parrots in both seasons were identified. Our study suggests that this parrot has a generalist diet. The information on food items produced by citizen scientists was greater than that obtained by ornithologists. Considering these two sources of information, 94 species of 35 plant families are currently known to be part of its diet. Of this total richness, 52 species (55%) were recorded exclusively by citizen scientists. Therefore, photographic records available in online citizen science databases, such as WikiAves, can improve our knowledge about aspects of the feeding ecology of Neotropical parrots.</p>
