Journal of Avian Biology, 2005 Patterns of feather wear in birds captured in spring have traditionally been analysed to describe the extent of winter moult in long‐distance migrants. However, the interpretation of feather wear may be rendered extremely difficult due to long moult periods, by the progress of the season, and by the existence of complex moult ...

Stable isotope analysis provides new information on winter habitat use of declining avian migrants that is relevant to their conservation [PDF]
, 2012 Winter habitat use and the magnitude of migratory connectivity are important parameters when assessing drivers of the marked declines in avian migrants. Such information is unavailable for most species.

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 ...

Moult Strategies Affect Age Differences in Autumn Migration Timing in East Mediterranean Migratory Passerines. [PDF]
PLoS ONE, 2016 Adult passerines renew their flight feathers at least once every year. This complete moult occurs either in the breeding areas, just after breeding (summer moult), or, in some long-distance migratory species, at the non-breeding areas, after arrival to ...

Silver spoon effects on plumage quality in a passerine bird [PDF]
Royal Society Open Science, 2015 A silver spoon effect means that individuals who develop under favourable circumstances enjoy a fitness or performance advantage later in life. While there is large empirical support for silver spoon effects acting on different life-history traits in ...

Phenotypic flexibility and the evolution of organismal design [PDF]
, 2003 Evolutionary biologists often use phenotypic differences between species and between individuals to gain an understanding of organismal design. The focus of much recent attention has been on developmental plasticity – the environmentally induced ...

Journal of Avian Biology, 2022 Plumage ornamentation in birds serves critical inter‐ and intra‐sexual signaling functions. While carotenoid‐based plumage colouration is often viewed as a classic condition‐dependent sexually selected trait, plumage colouration can be influenced by a ...
