A flock of Crimson-fronted Parakeets (Aratinga finschi) call in the forest off the road leading out of Bribri, near Puerto Viejo de Talamanca (Costa Rica), 6/22/99.
This is a flock of Orange-chinned Parakeets (Brotogeris jugularis) in flight. This is certainly one of the most common parrots in Costa Rica - Usually they travel in large flocks, and they always, always chatter. (Costa Rica)
