Birds with large distributions often inhabit areas containing different environments, this range of conditions in turn can generate different phenotypes specific to the environment (Botero and Campos, 2006). Studying this phenotypic variation helps to clarify the relationship between animals and their environment. This study compared morphology and molt patterns in Band-tailed seedeater (Catamenia analis) from 2012 to 2017 in two localities: Santa Eulalia River Biological Station (STEU) with an altitude of 2300 masl and Vivero Forestal Banding Station (VIFO) with an altitude of 247.3 masl. Both stations are located in the department of Lima and are separated by more than 50 km. Anova Factorial test and Non-Parametric Scheirer-Ray-Hare test indicate that the two populations of C. analis are similar in morphology except in weight. Additionally, in terms of age and sex, wing length and tail length were significantly different. Similarly, no variation was found in pre-formative and pre-alternate molt patterns. In other words, the 2000 m of difference in altitude and the 50 km of separation between the two populations are not sufficient to generate differences in morphology or in molting patterns. On the other hand, molt seasonality is different in both localities, resulting in a greater number of molting individuals in the months of July to September in the locality of STEU in the 5 years of sampling. In contrast, in the locality of VIFO fewer molting individuals and a greater proportion of adult plumage were found for the years of the study.
