“…In Florida (USA), monk parakeets have been reported to cause electric shortages while building nests in electric towers, costing as much as USD 585,000 for repairs (Avery et al, 2006), but there is no evidence of that occurring in Puerto Rico. Moreover, wild and captive Psittaciformes are known vectors of avian and diseases and parasites, and also human diseases (Clark et al, 1988;Orosz et al, 1992;Magnino et al, 1996;Mase et al, 2001;Azevedo, 2014;Done & Tamura, 2014;Briceno et al, 2017). We found an unidentified species of mite (probably Pararalichus) on white-winged parakeets.…”

Puerto Rico has experienced multiple introductions of Psittaciformes which have established self-sustaining populations, and the white-winged parakeets (Brotogeris versicolurus) has been considered the most successful invasive psittacine species in the island. In this study, we evaluated their population size, calculated growth rates and estimated the breeding proportion in two populations by performing roost counts for four consecutive years in addition to evaluating their range expansion. We also assessed their diet and breeding ecology. Population estimates parakeets during the study period showed a steady increase, with a maximum of 3,010 individuals in the San Germán population, and a maximum of 3,128 individuals in the San Patricio population. Both populations exhibited a geometric mean population growth rates of 25% per year. As expected, the data indicates that the populations experienced a lag-phase and prior to growing exponentially. This is supported by the island-wide sighting trends and range expansion. Moreover, we detected range expansion during our study via colonization of new areas. The population estimates and population growth rates, along with the sighting trends and their wide distribution makes the white-winged parakeet the most successful psittacine species in Puerto Rico. The factors leading to their invasion success are likely to include propagule pressure, their diet breath and their capability as primary nesters in termite mounds, which are abundant in the island. Currently, the growth rate of the whitewinged parakeet does not appear to be limited by any predator, resources or nest availability, and we expect them to continue increasing and expanding their range.

Introduced psittacine birds can become highly invasive. In this study, we assessed invasions of Psittaciformes in Puerto Rico. We reviewed the literature, public databases, citizen science records, and performed in situ population surveys across the island to determine the historical and current status and distribution of psittacine species. We used count data from Ebird to determine population trends. For species whose populations were increasing, we modelled their potential distribution using niche modeling techniques. We found 46 Psittaciformes in Puerto Rico, of which 26% are only present as pets, at least 29 species have been reported in the wild, and of those, there is evidence that at least 12 species are breeding. Our results indicate that most introduced species which have been detected as established still persist, although mostly in localized areas and small populations. Clear evidence of invasiveness was found for Brotogeris versicolurus and Myiopsitta monachus, which have greatly expanded their range in recent years. Psittacara erythrogenys and Eupsittacula canicularis also showed population increases, although to a lesser degree. The niche models predicted suitable areas for the four species, and also indicate the potential for range expansion. We discuss the factors leading to invasion success, assess the potential impacts, and we discuss possible management strategies and research prospects.

“…However, avipoxvirus outbreaks have been reported in captive native [15] and exotic [39] Psittaciformes in Brazil, showing low and high mortality rates, respectively. BFDV has been recently detected in captive exotic and native species [17,18] in Brazil. Based on the initial findings of the present study, it is likely that wild parrot populations can still be unreached by the global spread of BFDV [40].…”

“…A neglected virus in wild birds, the avipoxvirus, has also caused an outbreak in psittacine species located in a facility in Brazil [15]. In addition, the Psittacine Beak and Feather Disease (PBFD) caused by a circovirus, is an exotic pathogen introduced in the country [16], that has been reported in exotic and native pet birds [17,18].…”

South America presents the greatest Psittacidae diversity in the world, but also has the highest numbers of threatened parrot species. Recently, exotic viruses have been detected in captive native psittacine birds in Brazil, however, their impacts on the health of wild parrots are still unknown. We evaluated the presence of Chlamydia psittaci, Psittacid alphaherpesvirus 1 (PsHV-1), avipoxvirus and beak and feather disease virus (BFDV) in wild Amazona aestiva, A.brasiliensis and A.pretrei nestlings and in wild caught A.aestiva nestlings seized from illegal trade. Samples were collected from 205 wild nestlings and 90 nestlings from illegal trade and pathogen-specific PCR was performed for each sample. Chlamydia DNA prevalence was 4.7% in A.aestiva and 2.5% in A.brasiliensis sampled from the wild. Sequencing revealed that the C.psittaci sample belonged to the genotype A. PsHV-1, avipoxvirus and BFDV DNA was not detected. These results have conservation implications since they suggest that wild parrot populations have a low prevalence of the selected pathogens and, apparently, they were not reached by the exotic BFDV. Stricter health protocols should be established as condition to reintroduction of birds to the wild to guarantee the protection of Neotropical parrots.
