Mb. Robbins et al., THE TREE LINE AVIFAUNA AT CERRO-MONGUS, PROV-CARCHI, NORTHEASTERN ECUADOR, Proceedings of the Academy of Natural Sciences of Philadelphia, 145, 1994, pp. 209-216
A total of 119 species were recorded in tree line/paramo habitat at Ce
rro Mongus, Prov. Carchi, Ecuador during March 1992. A complete specie
s list with relative abundance designations and habitat preferences is
presented. Comparison of our results with a well-surveyed site in ext
reme northern Peru reveal striking similarities in species composition
between these sites, even though they are separated by ca. 650 km.
