description |
Molting is an important process of birds’ natural history and learning about molt and plumage allows a better understanding of various aspects of birds’ life. In temperate zones, knowledge about molt strategy, type of plumage characteristics and their association with age are well documented. In contrast, knowledge about molt in Neotropical birds is not well developed. One species with numerous studies regarding molt in several localities is the widely-distributed Rufous-collared Sparrow (Zonotrichia capensis). These studies covered various localities along the species range, facilitating comparisons among populations, and providing an excellent model for the study of plumage and molt variation. In this study, I described both molt strategy and extent of molt Z. capensis costaricensis, through sampling data for one year at two localities in Bogotá city. I captured and banded Z. capensis individuals and collected information about characteristics such as molt limits, skull ossification and iris coloration, which allow for the identification of molt/plumage type and its relation to age categories of a cycle-based age classification system. I found that Z. capensis has a complex basic strategy, where all prebasic molts, including prejuvenal molt, are complete and the preformative molt is a partial molt. The results are congruent with previous findings for this species in some areas. Nevertheless, the molt varies largely in Z. capensis across its distribution and individuals out of Neotropics have an additional partial-incomplete prealternate molt and it is still unknown why. |

En zonas templadas, el conocimiento sobre las estrategias de muda, las características de cada tipo de plumaje y su relación con la edad del ave, son bien conocidas. Por el contrario, en el neotrópico, este conocimiento no está bien desarrollado. Una especie con bastantes estudios sobre muda en varias localidades es el ampliamente distribuido Copetón (Zonotrichia capensis). Esos estudios cubren localidades de su ámbito geográfico facilitando comparaciones entre poblaciones y proveyendo un excelente modelo para estudiar la variación del plumaje y la muda. En este estudio, determiné el alcance y la estrategia de muda de Z. capensis costaricensis mediante muestreos durante un año en dos localidades de Bogotá. Capturé y anillé individuos de Z. capensis y tomé información de características como los límites de muda, osificación del cráneo y color del iris que me permitieron identificar el tipo de plumaje/muda y relacionarlo con una categoría de edad del sistema de clasificación de edad basado en los ciclos de muda. Encontré que Z. capensis tiene una estrategia de muda básica compleja, donde todas las mudas prebásicas, incluida la prejuvenil, son completas y la muda preformativa es parcial. Estos resultados son congruentes con los de otras regiones. Sin embargo, la muda de Z. capensis varía mucho, e individuos lejos de los trópicos tienen una muda alterna parcial-incompleta adicional y aún desconocemos por qué.application/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Instituto de Ciencias Naturaleshttps://revistas.unal.edu.co/index.php/cal/article/view/63337Universidad Nacional de Colombia Revistas electrónicas UN CaldasiaCaldasiaCueva, Diego (2018) Molt strategy and aging of Rufous-collared Sparrow (Zonotrichia capensis) in Bogotá, Colombia.
