“…A priori, the absence of competent insect vectors in the area or their inability to bite Monk parakeets could also explain the absence of Plasmodium infections. However, invasive populations of Monk parakeets are affected by different arthropod ectoparasites in the invaded areas [27,57,58], including blood-sucking mosquitoes [30]. Monk parakeets are hosts of mosquitoes including Cs.…”

Alien mosquito and vertebrate host species may create novel epidemiological scenarios for the transmission of pathogens naturally circulating in the invaded area. The exotic Monk parakeet (Myiopsitta monachus) has established populations in Europe and is currently considered an invasive pest. Due to their high abundance in urban areas, Monk parakeets could be involved in the transmission of pathogens, potentially affecting wildlife and livestock. To test this hypothesis, we determined the prevalence and diversity of three vector-borne parasites, namely Plasmodium, Haemoproteus and Leucocytozoon, in Monk parakeets from Barcelona. Many areas of southern Europe shelter high densities of the invasive Asian tiger mosquito Aedes albopictus, which in addition to native mosquito species could affect the transmission of mosquito-borne parasites, such as avian Plasmodium. Thus, we also sampled mosquitoes in the area to trace their blood-feeding hosts and determine the presence of Plasmodium parasites. Monk parakeets were neither infected by Plasmodium nor by Haemoproteus parasites, and only five individuals (3.13%; n = 160) were infected by Leucocytozoon. Monk parakeets were bitten by Culiseta longiareolata and represented 9.5% of Culex pipiens blood meals. The invasive Ae. albopictus showed a clear anthropophilic feeding pattern, with humans dominating its diet. Three Plasmodium lineages were detected in pools of Cx pipiens. These results suggest that Plasmodium circulating in the area cannot develop in the invasive Monk parakeet, in spite of the relatively high fraction of native mosquito vectors feeding on this species in its invaded distribution range.

“…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.
