Large migratory birds may bring along stores in order to survive adverse conditions and produce a clutch upon arrival ('capital breeders') or they may acquire all the necessary resources on the breeding grounds ('income breeders'). Whether birds[...]

Little empirical information exists to assess to what degree geese use a capital versus income breeding strategy for investing nutrients into eggs. We used stable isotope methods to directly estimate the sources of protein deposited into egg yol[...]

The nutritional quality of forage plants varies in space and time. This variation is presumed to drive the annual migration of herbivore species which follow peaks in the availability of high quality forage between sites. The green-wave hypothes[...]

Conventional approaches to measuring endogenous nutrient allocations to reproduction in birds have relied on the sampling of several individuals within populations in order to contrast mass gains of the clutch with mass loss of the laying female[...]

Long-distance bird migration consists of several flight episodes interrupted by a series of resting and refuelling periods on stopover sites. We assessed the role of food availability as the determinant of staging decisions focusing on the follo[...]

Egg formation is a demanding process both in terms of energy and nutrient requirements. Birds must not only collect specific nutrients for egg formation, but must do so over a brief period when food may not yet be plentiful. Supplementary feedin[...]
