The effects of annual cycle stages and life-history traits on feather abrasion by Yosef Kiat, Quentin Dupriez, Gina Pyo, Oliver J. L. Fox, Rafi Paz, Hans-Jürgen Eilts, Carlos Talabante, Nir Sapir

“…The timing of feather moult plays a pivotal role in influencing abrasion rates during the breeding season, with species that undergo moult nearer to the breeding season, during winter (pre-breeding moult), showing significantly lower abrasion rates than those moulting before the autumn migration (post-breeding moult), likely a result of the weakening of the feather structure over time. These findings highlight the importance of moult timing for feather abrasion rate and maintaining plumage integrity during the reproduction season. …”
