Data on the interactions between the order Psittaciformes and the anthropogenic environment are still insufficient and have not been systematized, especially in the Neotropical region. This is despite the fact that cities are the everyday territory shared by these birds and the vast majority of those of us who study them. As a consequence of this coexistence, the volume of accumulated knowledge is probably significantly greater than the formal scientific contributions on the subject. In this survey, information was compiled on the wild parrots inhabiting cities in the Southern Cone of South America, based on surveys with key informants. The results obtained highlighted the presence of a large number of parrots species that form part of the urban avifauna of the region, between 67% to 90% of the total number of species of the order cited for each territory evaluated. The greatest species richness and the number of breeding species was associated with the large cities located in middle and low latitudes. We confirmed breeding within the cities for more than 40% of the species mentioned. Seventy-five per cent of the species reported are native to the study area, the rest originating from other regions of South America or other continents. Quarter of the reported species are considered threatened and almost 50% have declining populations. Urban parrots represent a challenge in the search for urban models compatible with biodiversity conservation, in the designing of innovative conservation strategies that respond to the new challenges posed by a constantly growing human population.

La lora nuca amarilla, Amazona auropalliata ha logrado establecer poblaciones silvestres adaptándose a entornos urbanos. En esta nota se presentan los resultados del registro de individuos en sus rutas a los dormitorios comunales. Se hicieron observaciones entre abril 2020 a marzo 2021, desde cuatro puntos de avistamiento en el noreste de la ciudad de San Salvador, con un promedio de 35.76 min, para un total de 170 conteos y 100.06 horas de observación. Los resultados arrojaron un promedio de 2.42 individuos en 125 observaciones exitosas, con una ocurrencia entre las 17:26 a las 18:29 horas, existiendo más registros en el periodo de abril a julio, cuando la especie no se está reproduciendo, hay más juveniles volando y las condiciones climáticas son favorables para la observación. El análisis de correlación de Spearman entre la puesta del sol y la hora de paso de los loros (R2 = 0.26) evidencia que los movimientos vespertinos no están influenciados por el fenómeno.

“…Clearly, for any lineage to successfully colonize six continents, while occupying habitats that include both open desert and tropical rainforest, necessitates a high degree of behavioral flexibility [ 1 , 30 , 51 ]. Indeed, the dietary malleability of many parrot species allows them to find and exploit food resources across many different landscapes [ 1 , 43 , 70 , 71 ]. They demonstrate a wide range of food preferences, utilizing both native and non-native food sources [ 71 , 72 , 73 ].…”

Parrots (Order: Psittaciformes) represent one of the most striking and ecomorphologically diverse avian clades, spanning more than two orders of magnitude in body size with populations occupying six continents. The worldwide diaspora of parrots is largely due to the pet trade, driven by human desire for bright, colorful, and intelligent animals as companions. Some introduced species have aptly inserted themselves into the local ecosystem and established successful breeding colonies all around the globe. Notably, the United States is home to several thriving populations of introduced species including red-masked parakeets (Psittacara erythrogenys), monk parakeets (Myiopsitta monachus), nanday conures (Aratinga nenday), and red-crowned amazons (Amazona viridigenalis). Their incredible success globally begs the question as to how these birds adapt so readily to novel environments. In this commentary, we trace parrots through evolutionary history, contextualize existent naturalized parrot populations within the contiguous United States, and provide a phylogenetic regression analysis of body mass and brain size based on success in establishing breeding populations. The propensity for a parrot species to become established appears to be phylogenetically driven. Notably, parrots in the family Cacatuidae and Neotropical Pyrrhua appear to be poor at establishing themselves in the United States once released. Although brain size among Psittaciformes did not show a significant impact on successful breeding in the continental United States, we propose that the success of parrots can be attributed to their charismatic nature, significant intelligence relative to other avian lineages, and behavioral flexibility.
