This review concentrates on the physiological responses, and their control, in freely diving
birds and mammals that enable them to remain submerged and sometimes quite active for …

1. Mean levels of body temperatures (Tb) for all birds are (resting/active phase/high activity)
38.54±0.96 (N= 203), 41.02±1.29 (N= 724) and 43.85±0.94° C (N= 74). 2. 2. Tb is higher in …

Shorebirds are the most visible inhabitants of coastal wetlands worldwide. Many undertake
spectacularly long flights between their wintering and breeding grounds, embodying the …

I have chosen to address three major areas in the energetics of free-ranging adult seabirds:
basal metabolism, locomotion, and energy budgets. More information is available on basal …

For birds that breed in areas with severe winters, latitudinal and/or altitudinal migration
provides the possibility of moving to places where cold and inclement weather and …

In response to climate warming, migratory animals can alter their migration so that different
events in the annual cycle are better aligned in space and time with suitable environmental …

1. We measured prey selection and habitat profitability of common eiders Somateria
mollissima L. wintering in the Gulf of St. Lawrence, Quebec, Canada. Prey selection was …

As heart rate (f H) can be used to determine the energy expenditure of black-browed
albatrosses (Diomedea melanophrys)(Bevan et al. 1994), data loggers-recording f H and …

Although the replacement of feathers apparently represents the major event of somatic
production in the annual cycle of wild birds, knowledge about the energetics of molt has …

ABSTRACT The South Georgian shag (Phalacrocorax georgianus) shows a remarkable
diving ability comparable to that of penguins, yet nothing is known of the physiology of these …
