It is suggested that P. u. unicinctus and L. a. aegithaloides are resident species in suitable habitat, the former throughout the province and the latter in the northern portion. Crocethia alba is considered an occasional, non breeding visitor to Magallanes and H. r. erythrogaster as probably a rather common non breeding visitor.PDFesFaunaAvesArticulo
