“…Since 1984, a breeding population of yellow-headed Amazon parrots (A. oratrix) has established in Stuttgart (Martens et al, 2013), starting with a single pair which bred for the first time in 1985; reproduction occurred every year, bringing the population to nearly 50 individuals in 2015 (D. Franz, pers. comm., 2015).…”

Worldwide distribution of non-native Amazon parrots and temporal trends of their global trade.-Alien species are the second leading cause of the global biodiversity crisis, after habitat loss and fragmentation. Popular pet species, such as parrots and parakeets (Aves, Psittaciformes), are often introduced outside their native range as a result of the pet trade. On escape from captivity, some such species, such as the ring-necked parakeet and the monk parakeet, are highly invasive and successfully compete with native species. Populations of Amazon parrots (Amazona spp.) can be found throughout the world, but data on their status, distribution and impact are incomplete. We gathered and reviewed the available information concerning global trade, distribution, abundance and ecology of Amazon parrots outside their native range. Our review shows that at least nine species of Amazon parrots have established populations outside their original range of occurrence throughout the world (in Europe, South Africa, the Caribbean islands, Hawaii, and North and South America). Their elusive behaviour and small population size suggest that the number of alien nuclei could be underestimated or at undetected. Despite international trade bans, the large trade of wild-caught Amazon parrots in past decades appears to have contributed to the establishment of alien populations worldwide. Establishment success seems to differ geographically. While European populations are still small and growing slowly, USA populations are large and expanding geographically. This difference is not related to large propagule pressure (trade) but possibly to a better niche match between native and introduced ranges. Amazona aestiva is the most frequently encountered Amazona parrot, with at least eight alien populations reported to date. All these populations, with the exception of those in the USA where the climate is more suitable for their establishment, are composed of a low number of individuals even though they have been established for a long period of time. Further research is required as little information is available on the ecology and potential impact of these alien populations. ResumenDistribución en el mundo de los loros introducidos del género Amazona y tendencias temporales de su comercio a escala mundial.-Las especies exóticas son la segunda causa de la crisis de biodiversidad mundial, precedida por la pérdida y la fragmentación del hábitat. Algunas especies populares como mascotas, como los loros y las cotorras (Aves, Psittaciformes) suelen introducirse fuera de su área de distribución nativa a consecuencia del comercio de animales de compañía. Si escapan de su cautiverio, algunas de estas especies, como la cotorra de Kramer y la cotorra argentina, son sumamente invasivas y compiten con las especies autóctonas. Las poblaciones de loros del género Amazona pueden encontrarse en todo el mundo, pero los datos relativos a su estado, distribución y efectos son incompletos. Recopilamos y examinamos la información disponible relativa a la ecología,...

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.

“…Los psitácidos son uno de los grupos con mayor éxito en el establecimiento de especies no nativas después de los pinzones (Lockwood, 1999). La alta capacidad de adaptación les permite colonizar ambientes urbanos y rurales fuera de su hábitat y rango geográfico original; un claro ejemplo son las poblaciones de Ara severus (Linnaeus, 1758) que se han aumentado en Norteamérica, al igual que Psittacula krameri (Scopoli, 1769) en varios países europeos (Cassey et al, 2004;Burger y Gochfeld, 2005;Butler, 2005;Lara-Vásquez et al, 2007;Martens et al, 2013;Arbeláez-Cortes et al, 2015;Toft y Wright, 2015).…”

“…Cabe resaltar que por la alta capacidad de adaptabilidad que exhiben los psitácidos, la oferta de recursos como alimento y el hábitat disponibles para poder cumplir sus ciclos de vida y las condiciones para eventos reproductivos están presentes, lo que permitirá el crecimiento de las poblaciones, como se ha visto en el municipio de Medellín ya con poblaciones estables de varias especies del genero Ara (Lara-Vásquez et al, 2015). Este patrón también ha sido observado en otras especies de psitácidos no nativos en países europeos y en Norte América (Butler, 2005;Muñoz y Real, 2006;MacGregor-Fors et al, 2011;Martens et al, 2013), donde su presencia es mayor y las poblaciones crecen en áreas altamente influenciadas por humanos.…”

“…De igual forma la manipulación de especies para crear híbridos se realiza frecuentemente en tiendas de mascotas y se les asocia con una alta dependencia humana (McCarthy, 2006;Forshaw y Knight, 2010;Parr et al, 2010;Toft y Wright, 2015). Especies, como los psitácidos, que poseen amplias dietas y distribución tienden a tener mayor éxito en su establecimiento (Cassey et al, 2004;Lara-Vasquez et al, 2015), como es el caso de las poblaciones ya naturalizadas establecidas en zonas templadas, cuyo crecimiento poblacional solo se ve limitado por los cambios estacionales del ambiente (Martens et al, 2013). Por lo anterior y por su alta capacidad de adaptación a estos ambientes rurales y urbanos existe la necesidad de que se realice un monitoreo constante.…”

Colomb. 2016;21(3):653-656. DOI: http://dx.doi.org/10.15446/abc.v21n3.55546 RESUMENLa naturalización de especies no nativas ha sido bien documentada en zonas templadas, pero poco se sabe sobre las regiones tropicales. Entender el proceso de expansión de rango geográfico de especies generaría estrategias de manejo y conservación. En esta nota se documenta la presencia de Ara macao y Amazona ochrocephala, así como el primer registro de un híbrido en estado salvaje en las zonas urbanas y rurales del departamento del Quindío (Andes centrales) de Colombia. Por medio de observación directa se logró identificar una alta capacidad de adaptación de la especie A. macao e híbrido a las condiciones rurales y urbanas de las zonas bajas del departamento entre los municipios de Armenia y la Tebaida. Se observaron varios individuos de A. ochrocephala las cuales se catalogaron como aves errantes. En total se reportan 17 especies de psitácidos dentro del departamento del Quindío. Se recalca la importancia de la presencia de estas aves no nativas en ecosistemas donde no habitan naturalmente por sus posibles implicaciones al cambiar la composición de la avifauna nativa, así como se incentiva el monitoreo para futuros planes de manejo y conservación.Palabras clave: composición de aves, ecosistemas urbanos, especies no nativas, naturalización. ABSTRACTThe naturalization of non-native species has been well documented in temperate zones, but little is known about tropical regions. Understanding the process of expanding geographic range of species generated management and conservation strategies. In this note is documented the presence of Ara macao and Amazona ochrocephala, and the first record of a hybrid in the wild in urban and rural areas of the department of Quindío, Central Andes of Colombia. Through direct observation it was possible to identify a high adaptability of the species A. macao and hybrid to the rural and urban conditions of low-lying areas of the department between the municipalities of Armenia and Tebaida. Several individuals of A. ochrocephala which were categorized as wandering birds were observed. A total 17 species of parrots in the department of Quindío are reported. The importance of the presence of these non-native birds in ecosystems where naturally inhabit its possible implications to changing the composition of the native avifauna is emphasized, as well as monitoring for future conservation and management plans are encouraged.
