Plasma metabolites reflect seasonally changing metabolic processes in a long-distance migrant shorebird (Calidris canutus) [PDF]
, 2002 Migrant birds have tightly scheduled annual cycles consisting of several distinct life cycle (sub-)stages such as reproduction, migration, moult and overwintering, each of which have specific metabolic requirements (e.g., fattening during migration ...

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 ...

Implantation of subcutaneous heart rate data loggers in southern elephant seals (Mirounga leonina) [PDF]
, 2017 Unlike most phocid species (Phocidae), Mirounga leonina (southern elephant seals) experience a catastrophic moult where they not only replace their hair but also their epidermis when ashore for approximately 1 month.

Differences in tail feather growth rate in storm-petrels breeding in the Northern and Southern hemisphere: a ptilochronological approach [PDF]
PeerJ, 2019 Moulting and breeding are costly stages in the avian annual cycle and may impose trade-offs in energy allocation between both stages or in their timing.

Premigratory moult in the Lesser Kestrel Falco naumanni
Avocetta, 2019 Moult is one of three major energy-demanding life-history events in the annual cycle of birds but unlike breeding and migration it is poorly studied. Most of the long-distance migratory raptors suspend moult during migration and then finish it in their ...

Defining moults in migratory birds: a sequence‐based approach
Journal of Avian Biology, 2022 Two broad nomenclatures have emerged to describe moult strategies in birds, the ‘life‐cycle' system which describes moults relative to present‐day breeding and other life‐history events, and the Humphrey–Parkes (H–P) system which reflects the evolution ...

Temporal and spatial differences in the post-breeding behaviour of a ubiquitous Southern Hemisphere seabird, the common diving petrel [PDF]
Royal Society Open Science, 2020 The non-breeding period plays a major role in seabird survival and population dynamics. However, our understanding of the migratory behaviour, moulting and feeding strategies of non-breeding seabirds is still very limited, especially for small-sized ...

Influence of fasting during moult on the faecal microbiota of penguins. [PDF]
PLoS ONE, 2014 Many seabirds including penguins are adapted to long periods of fasting, particularly during parts of the reproductive cycle and during moult. However, the influence of fasting on the gastrointestinal (GI) microbiota has not been investigated in seabirds.
