Many studies have reported statistically significant associations between bird migratory
phenology and climatic variables, and, consequently, it is mostly accepted that recent shifts …

Abstract Changes in phenology and distribution are being widely reported for many
migratory species in response to shifting environmental conditions. Understanding these …

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 …

The exploration of animal migration has entered a new era with individual-based tracking
during multiple years. Here, we investigated repeated migratory journeys of a long-distance …

Birds selecting a nest site have to find the best compromise between the risk of encountering
predation, the availability of food near to the nest and microclimatic requirements. As the …

Faster migration in spring than in autumn seems to be a common pattern in birds. This has
been ultimately explained by seasonally different selection pressures. Variation in migration …

While the evidence for advancement of spring phenology of animals and plants in response
to recent climate change is overwhelming and undisputed, formal meta-analyses of avian …

Although elaborate bird song provides one of the prime examples of a trait that evolved
under sexual selection, it is still unclear whether females judge the quality of males by …

Global climate change is having a major impact on the viability of species. Whether a
particular population will survive or go extinct will depend on its potential to adapt to new …

Butler (2003) used first arrival dates (FADs) of 103 migrant birds in northeastern USA and
found that both long‐distance migrants (LDMs; wintering south of the USA) and short …
