RODRIGUEZ-RUIZ, Erick R. et al. Translocation of the black-throated magpie-jay Calocitta colliei (Passeriformes: Corvidae) in Ciudad Victoria, Tamaulipas, Mexico. Huitzil [online]. 2017, vol.18, n.1, pp.24-32. ISSN 1870-7459.

Although the expansion of the distributional range of species occurs naturally, translocation exerted by the humans may result in a threat to other species. In this study, we report the first records of the black-throated magpie-jay (Calocitta colliei) in Ciudad Victoria, Tamaulipas, northeastern Mexico whose presence may be due to the transfer in captivity, release or escape and permanence in the area. Records were obtained occasionally from 2009 to 2015. The incidence of C. colliei individuals in urban areas assumes a positive association of commensalism with humans, in which the species adapts to the local urban area, preferably in areas of intermediate disturbance between human density and green areas with exotic fruit trees. This may act as an ecological barrier that isolates the species from the natural environment. We suggest taking action on preventive measures at the local scale, and generating basic information on the distribution of C. colliei for assessing short-term effects on native species (competition, displacement and other ecological interactions) and habitat preferences in urban areas, to design management plans and environmental education programs in the region.
