moult: AnRPackage to Analyze Moult in Birds [PDF]
Journal of Statistical Software, 2013 Moult is the process by which birds replace their feathers. It is a costly process in terms of energy and reduced flight ability but necessary for the maintenance of the plumage and its functions. Because birds generally avoid to moult while engaged with other energy demanding activities such as breeding and migration, the analysis of moult data gives ...

Moult habitat, pre- and post-moult diet and post-moult travel of Ross Sea emperor penguins [PDF]
Marine Ecology Progress Series, 2004 During a series of transect legs through the pack ice of the eastern Ross Sea, aboard the RV icebreaker 'Nathaniel B. Palmer', we: (1) assessed the habitat chosen for moulting by emperor penguins, Aptenodytes forsteri, (2) determined their pre- and post-moult diets, (3) measured the pre- and post-moult body mass of the birds, and (4) tracked their post-
