    The Puerto Rican parrot, Amazona vittata vittata, is an endemic bird of Puerto Rico and an endangered specie. The purpose of this research was to recover mycelial fungi in the nesting structures, claws, beak, and vent from parrots in Río Abajo forest in Arecibo, Puerto Rico. Samples were taken from wood shavings of 25 nests structures and using the pour plate technique, colonies were isolated in Petri dishes containing Rose Bengal Agar. Using a sterile swab, samples from the claws, beak, and vent of 25 parrots were taken. Samples were striated in Petri dishes with Malt Extract Agar. Fungal species belonging to Aspergillus spp. and Penicillium spp. were subcultivated in Czapek Yeast Extract Agar, Malt Extract Agar, and 25 % Glycerol Nitrate Agar. Other fungal genera were subcultivated in Potato Dextrose Agar. To identify the fungal species recovered macroscopic and microscopic characteristics and taxonomic keys were used. Penicillium camembertii, Penicillium spp., Mucor hiemalis f. hiemalis, Mucor racemosus f. chibinensis, and Aspergillus candidus were the most frequent species. These species are common environmental contaminants, some of them produce strong toxins, and some could be oportunistic organisms. Daily cleaning of materials that are in contact with parrots can help control these fungi.
