Abstract Monitoring population trends of alien species is pivotal to design effective management plans preserve native biodiversity, particularly urban areas, where most populations birds are established. Urban wildlife rescue centers, with personnel trained record species, age and sex each individual brought by the public, may represent a reliable citizen-science based method estimate both loc...

We studied the reproductive ecology of the Ringed Warbling-Finch Poospiza torquata and the Cinnamon Warbling-Finch P. ornata during four breeding seasons in the Reserve of Ñacuñán, western Argentina. We described the breeding biology of both species, examined temporal variation in reproductive parameters under contrasting weather conditions, and compared reproductive traits of these sympatric P...

A flock of Indian Ringneck parakeets (Psittacula krameri manillensis) was imported to the United States from Australia. Soon after, 1 parakeet suddenly died, and a second parakeet died after a 2-day course of illness, which consisted of anorexia, lethargy, emaciation, and dyspnea. At necropsy, the affected birds had diffuse consolidation and red discoloration of the lungs, as well as thickened,...

This study presents the results of object-based classifications assessing the potential of bi-temporal Pléiades images for mapping broadleaf and coniferous tree species potentially used by the ring-necked parakeet Psittacula krameri for nesting in the urban area of Marseille, France. The first classification was performed based solely on a summer Pléiades image (acquired on 28 July 2015) and th...

The genus Pyrrhura includes small to medium-sized parakeets, which inhabit both low and dry alongside tall rainforests, mainly in South America. Pyrrhura molinae is still common, year round, in the markedly seasonal forests of western Brazil. This parakeet, as well as most Neotropical parrots, continues to be poorly understood. Hence, in the present study I examined their foraging ecology both ...

Abstract Over 40 species of parrots, members order Psittaciformes, have established nonnative populations globally. Monk parakeets ( Myiopsitta monachus ) are among the most invasive bird worldwide. In their introduced range, monk caused negative impacts on native species, habitats, economies, and human safety. Lethal population management has been complicated by intelligence parakeets, as they...
