Shifts in species' distribution and abundance in response to climate change have been well
documented, but the underpinning processes are still poorly understood. We present the …

From the red grouse to the Ethiopian bush-crow, bird populations around the world can
provide us with vital insights into the effects of climate change on species and ecosystems …

Shifts in phenology are already resulting in disruptions to the timing of migration and
breeding, and asynchronies between interacting species,,,–. Recent syntheses have …

One consequence of climate change is an increasing mismatch between timing of food
requirements and food availability. Such a mismatch is primarily expected in avian long …

Many bird species are advancing the timing of their egg-laying in response to a warming
climate. Little is known, however, of whether this advancement affects the respective length …

To the untrained eye, all reed warblers may look alike. Anyone who takes a closer look will
quickly realize that there is in fact an amazing spectrum of different ecological and adaptive …

Understanding how weather influences survival and reproduction is an important
component of forecasting how climate change will influence wildlife population viability. Nest …

Most bird species do not breed at just any moment in the year: breeding is mostly confined to
a restricted period and is rather synchronized within populations. Seemingly, each species …

Most phenological traits are extremely sensitive to current climate change, and advances in
the timing of important life‐history events have been observed in many species. In birds …

Climate change is predicted to be the major threat to biodiversity by 2100, when the global
average temperature may increase by 5--6 degrees, according to current predictions and …
