Wild populations of the Puerto Rican parrot
El Yunque, Caribbean National Forest – 20 – 30
This is the original population that survived the near extinction event
Rio Abajo Forest population 30-40
This is a new population which was started with birds released from captivity. Rio Abajo used to be a stronghold of the PR.
A Short History of the Vivaldi (Rio Abajo) Aviary
Starting date – In 1989 30 Hispaniolan parrots were transferred from the Luquillo aviary to the Rio Abajo aviary to serve as sentinels to detect the presence of infections diseases, to put operational logistics to test, and to evaluate the capacity of the technical staff.

Captive management Philosophy:
The Rio Abajo aviary is a captive breeding facility that is not open to the public. The principal purpose of the aviary is to be a bank of genetic material representative of the species to provide parrots for future reintroductions into the wild. The facility is equipped with everything necessary to perform many procedures without having to remove the birds from the property. We use a management method that is minimally invasive to the birds’ territories, which are composed of different areas of breeding cages. We use large sized flight cages, of 60 feet in length and 14 feet in height, to socialize the young parrots and so that they can form pairs in a free and natural manner so as to produce pairs of the best quality. We try to maintain an environment that is positively stimulating to the majority of the reproductive pairs and results in less stress.
In the Rio Abajo aviary we have a deep respect for the Puerto Rican parrot as an animal with a large cognitive capacity that needs to be provided not just with the basic necessities of food and water, but also of an environment adequate for exercising the full realm of behavior that they possess. To be able to fill their mental needs we provide spacious cages, fruit, branches, leaves, and toys made of wood, coconut, and rope. The adult breeding cages are separated from one another by barriers of vegetation and dark screen. We severely limit the access of humans in the areas of breeding cages. We try to reduce to as little as possible the amount of contact the parrots have with humans to avoid the parrots’ becoming accustomed to human contact. We carefully study the behavior of the young adults and reproductive pairs to look for what might help us to stimulate reproduction in captivity. We maintain a complete database of our activities with the parrots to be able to evaluate the results of our actions. We use the Hispaniolan parrot, Amazona ventralis, as foster parents to incubate eggs and raise PR parrot chicks. The eggs and chicks of the Hispaniolan parrots are used to provide practical experience to PR parrot pairs that are new and inexperienced in incubating eggs and rearing chicks
