Resumen

LONDONO-BETANCOURTH, JUAN CARLOS. DISCUSSIONS ABOUT THE PRESENCE OF BIRDS OF PREY, MIGRATORY BIRDS AND BIRDS UNDER SOME DEGREE OF THREAT IN THE CITY OF PEREIRA, RISARALDA. Luna Azul [online]. 2013, n.36, pp.134-164. ISSN 1909-2474.

The article presents a discussion that seeks to justify the presence of wild birds in the city of Pereira -emphatically birds of prey, migratory birds, or birds under some degree of threat- seeking to broaden the discussion of results presented in the previous article "Revision to Ornithological Diversity in Pereira." Fourteen (14) species of birds of prey (this is to say belonging to the families Cathartidae, Pandionidae, Accipitridae and Falconidae) which owe their presence to the fact that they do not depend on forests and can survive in urban areas; twenty-six (26) migratory species which, except for three species considered rare, all are common or fairly common and most frequent in open areas; seven (7) species under some degree of threat (threat mainly due to habitat destruction) considered as rare and local; and four (4) endemic species of which only one is considered rare; all others are common and within the city they find the different types of habitat they require. It is discussed and concluded that in general the species dealt with belong to open areas and do not depend on forests, are tolerant to intervened ecosystems and/or have some niche plasticity with their habitat needs and are able to find their ecological requirements in urban areas. Also that the habitat heterogeneity and the varied vegetation structure in urban areas contribute to the richness of species.
