Increased land use by polar bears (Ursus maritimus) due to climate‐change‐induced
reduction of their sea‐ice habitat illustrates the impact of climate change on species …

The first comprehensive review of all aspects of the biology of moult, drawing information
from across the literature and in all birds, from penguins to passerines. Feathers are …

Migratory flight requires birds to maintain intensive aerobic exercise for many hours or days.
Maintaining O2 supply to flight muscles is therefore important during migration, especially …

This paper reviews factors affecting site selection amongst waterfowl (Anatidae) during the
flightless remigial moult, emphasising the roles of predation and food supply (especially …

Animal‐borne logging devices are now commonly used to record and monitor the
movements, physiology and behaviours of free‐living animals. It is imperative that the …

Waterfowl undergo an annual simultaneous flight-feather moult that renders them flightless
for the duration of the regrowth of the flight feathers. In the wild, this period of flightlessness …

Surveys of gray seals (Halichoerus grypus) during the molt period, when they are abundant
on land, can be used to monitor changes in population size, but accurate interpretation of …

While many species suffer from human activities, some like geese benefit and may show
range expansions. In some cases geese (partially) gave up migration and started breeding …

Captured free‐living male mallard Anas platyrhynchos at Abberton in southern Britain
showed peak mass gain immediately prior to simultaneous remex moult. Individuals of both …

Birds employ varying strategies to accommodate the energetic demands of moult, one
important example being changes in body mass. To understand better their physiological …
