Habitat selection by the Monk Parakeet during colonization of a new area in Spain

The Monk Parakeet (Myiopsitta monachus) is a habitat generalist parrot from South America that has been introduced to and has expanded its range in Europe and North America. The aim of this study was to examine habitat selection in Monk Parakeets during the colonization of Barcelona, Spain, from 1992 to 1994. The Monk Parakeet showed a great selectivity in habitat choice, contrasting with the generalist behavior of the species in South America. The species inhabited urban parks with edible plants and palms (Phoenix spp.). Individuals showed a great specificity and preference for nesting in palms and palms appeared to be the main factor influencing the distribution and abundance of parakeets. Individuals showed a consistent preference for nesting in the tallest palms, probably as a way to reduce predation and human disturbance, although other characteristics also could affect the nest location. Implications of these findings for the biology and management of the species are discussed.
