Ibis, EarlyView.Moult strategies in birds can vary considerably even within a single species, particularly in terms of where moulting takes place. Yet, the factors underlying this variation and its consistency across years and individuals remain poorly understood. One such strategy, moult migration, involves individuals moving to a specific moulting location amid ...
