To understand the ecology of migratory animals it is important to link geographic regions
used by individuals including breeding, wintering, and intermediate stopover sites. Previous …

Waterbird hunting is a widespread activity in wetlands throughout Europe and constitutes
one of the most significant sources of disturbance during autumn and winter. The biological …

Climate warming challenges animals to advance their timing of reproduction [1], but many
animals appear to be unable to advance at the same rate as their food species [2, 3]. As a …

During egg‐formation, energy and protein are deposited in the developing eggs but are, at
the same time, needed by the laying female herself. This has been largely overlooked in the …

We relate variation in the timing of arrival by migrating birds breeding at northerly latitudes to
individual differences in the prior accumulation of energy stores. Balancing starvation risks …

We studied relationships between body size of female Black Brant goslings (Branta bernicla
nigricans) late in their growth period and first year survival, eventual adult body size …

Because eggs are composed of nutrients that are ultimately derived from the diet of adult
females, the relative abundance of naturally-occurring stable isotopes of carbon and …

The strategy of relying extensively on stored nutrient reserves for reproduction (capital
breeding) was thought to be common in large‐bodied birds breeding in harsh environments …

Spring migration is generally considered as a crucial period of the year for many birds, not
the least due to its supposed importance for subsequent breeding success. By reviewing the …

We explored predictive models relating body condition and age to nesting propensity, timing
of nest initiation, clutch size of first nests, aggregated nest survival, hatching success, and …
