The Santa Marta Parakeet (Pyrrhura viridicata) is a poorly studied species and several aspects of its biology remain unknown. This study carried out between July and December 2006 in the Cuchilla de San Lorenzo, Sierra Nevada de Santa Marta, describes its social behavior and vocalizations during foraging. During the first half of the morning, we recorded the greatest activity between 06:00 and 08:00 hours and group size ranged from three to 20 individuals, with a most frequent size of ca. 10 birds. Larger groups were associated with a concentrated source of food and with the start of the breeding season. We characterized four vocalizations associated with different stages of the events observed. Groups maintained high cohesion during foraging, which depended on group size and was related to the spatial distribution of individuals in the vegetation. Additionally, we noted the recurrent presence of parakeets in the same trees for weeks, which is common for other parrots, and was related to their foraging cycle and food availability. These data may allow identification of critical areas, resources and stages during the life cycle of the parakeet, which could be essential for conservation planning.
