Recent shifts in phenology in response to climate change are well established but often poorly understood. Many animals integrate climate change across a spatially and temporally dispersed annual life cycle, and effects are modulated by ecological interactions, evolutionary change and endogenous control mechanisms. Here we assess and discuss key statements emerging from the rapidly developing study of changing spring phenology in migratory birds. These well‐studied organisms have been… 

Climate change and timing of avian breeding and migration: evolutionary versus plastic changes

The literature is reviewed to disentangle the actions of evolutionary changes in response to selection induced by climate change versus changes due to individual plasticity, that is, the capacity of an individual to adjust its phenology to environmental variables, within the abundant literature on climate change effects on bird phenology.

Continent‐scale global change attribution in European birds ‐ combining annual and decadal time scales

This work finds that birds are affected by winter, spring, and summer conditions depending on the distinct breeding phenology that corresponds to their migratory strategy, and documents the potential of combining time scales and integrating both species attributes and environmental variables for global change attribution.

Widespread shifts in bird migration phenology are decoupled from parallel shifts in morphology.

It is shown that spring migration through Chicago has advanced while the timing of fall migration has broadened as a result of early fall migrants advancing their migrations and late migrants delaying their migrating, and there is no evidence that rates of phenological change across years, or migratory distance and breeding latitude, are predictive of rates of concurrent changes in morphological traits.

Individual repeatability of avian migration phenology: A systematic review and meta‐analysis

Timing of departure from the non-breeding grounds was more repeatable than timings of arrival at or departure from breeding grounds, suggesting that conditions encountered on migratory journeys and outcome of breeding attempts can influence individual variation.

A review and meta‐analysis of the effects of climate change on Holarctic mountain and upland bird populations

Mountain regions are globally important areas for biodiversity but are subject to multi- ple human-induced threats, including climate change, which has been more severe at higher elevations. We

Effects of climate change on European ducks: what do we know and what do we need to know?

A range of monitoring initiatives are proposed, including population surveys, breeding success monitoring schemes and individual duck marking, which should later be integrated through population modelling and adaptive management to fill gaps in information on climate change for ducks.

Evidence of the effects of climate change on landbirds in western North America: A review and recommendations for future research

Abstract: To evaluate the effects of climate change on landbirds in western North America, we reviewed the published literature on changes in avian phenology, geographic distribution, morphology,

Discerning the Environmental Drivers of Annual Migrations in an Endangered Amphibian

The prevalence of studies that discern the drivers of animal migrations is increasing exponentially, in line with raised concerns over climate-driven shifts in phenological patterns. Amphibians that

Climate Change and Phenological Mismatch in Trophic Interactions Among Plants, Insects, and Vertebrates

This work reviews whether this continuously ongoing phenomenon, also known as trophic asynchrony, is becoming more common under ongoing rapid climate change, and investigates limited evidence of phenological mismatch in mutualistic interactions.

Experience drives innovation of new migration patterns of whooping cranes in response to global change

It is shown that, for a long-lived social species, older birds with more experience are critical for innovating new migration behaviours, and groups containing older, more experienced individuals establish new overwintering sites closer to the breeding grounds, leading to a rapid population-level shift in migration patterns.



Disparities between observed and predicted impacts of climate change on winter bird assemblages

Examination of changes from 1975 to 2001 in three community attributes (species richness, body mass and occupancy) for 404 assemblages of terrestrial winter avifauna in North America containing a total of 227 species shows trends differed significantly from the spatially derived predictions, although richness showed broad congruence.

Responses to climate change in avian migration time - microevolution versus phenotypic plasticity

The meta-analysis confirmed a general advancement of avian migration time and that this advancement is correlated with climatic parameters, but large-scale geographical patterns and relationships with age at first reproduc- tion—a proxy of generation time—were less clear.

Avian distributions under climate change: towards improved projections

It is argued that further development of similar models in birds would complement existing empirical knowledge and theoretical projections and require the continued use of correlative approaches that may take on increasingly mechanistic components.

Evolutionary aspects of climate-induced changes and the need for multidisciplinarity

Climate change causes rapid changes in the distribution and site abundance of birds in winter

Detecting coherent signals of climate change is best achieved by conducting expansive, long‐term studies. Here, using counts of waders (Charadrii) collected from ca. 3500 sites over 30 years and

Impact of climate change on migratory birds: community reassembly versus adaptation

Aim Species can respond to global climate change by range shifts or by phenotypic adaptation. At the community level, range shifts lead to a turnover of species, i.e. community reassembly. In

Climate change and evolution: disentangling environmental and genetic responses

The available evidence points to the overall conclusion that many responses perceived as adaptations to changing environmental conditions could be environmentally induced plastic responses rather than microevolutionary adaptations, and clear‐cut evidence indicating a significant role for evolutionary adaptation to ongoing climate warming is conspicuously scarce.

Climate change and population declines in a long-distance migratory bird

In a comparison of nine Dutch populations, it is found that populations have declined by about 90% over the past two decades in areas where the food for provisioning nestlings peaks early in the season and the birds are currently mistimed.

Life history predicts advancement of avian spring migration in response to climate change

The results suggest that avian migration phenology adapts to climate change as a species-specific response, and that the degree of this response is fundamentally shaped by constraints and selection pressures of the species’ life history, and less so by the intensity of sexual selection.

Migratory behaviour constrains the phenological response of birds to climate change

Migratory birds may be unable to respond to climate change at their breeding grounds in the same way as residents because they do not experience local environmental conditions until migration has
