Abstract
- Body condition in individuals is intricately linked to behaviour, physiology, and immunity. This study investigated how seasonal factors, such as reproduction and moulting, influence the body condition of 21 tanager species in the Atlantic Forest. Utilising publicly available data, I employed phylogenetic generalised linear mixed models to dissect these influences. Notably, females with brood patches exhibited concurrent body and feather moult, suggesting simultaneous energy-costly constraints. Furthermore, females with brood patches displayed higher body condition, indicating proactive preparation or increased resource availability during breeding. Lastly, individuals moulting body feathers exhibited enhanced body condition, suggesting heightened foraging activity. These data suggest complex connections between sex, moulting, and reproductive status in tanagers in the Atlantic Forest. [ABSTRACT FROM AUTHOR]
