There have been numerous recent observations of changes in the behavior and dynamics of migratory bird populations, but the plasticity of the migratory trait and our inability to track small animals over large distances have hindered investigation of the mechanisms behind migratory change. We used habitat-specific stable isotope signatures to show that recently evolved allopatric wintering populations of European blackcaps Sylvia atricapilla pair assortatively on their sympatric breeding… Expand
Contemporary Evolution of Reproductive Isolation and Phenotypic Divergence in Sympatry along a Migratory Divide
TLDR
It is shown that differential migratory orientation facilitated reproductive isolation of sympatric populations within <30 generations, and it is hypothesized that restricted gene flow accelerates the evolution of adaptive phenotypic divergence toward the contrasting selection regimes. Expand
The Role of Seasonal Migration in Population Divergence and Reproductive Isolation.
TLDR
G gaps in understanding of the role of seasonal migration in the speciation process are identified and a framework to test the relative significance of reproductive barriers associated with variation in migratory behavior that might underlie population differentiation is proposed. Expand
Spatial Isolation and Temporal Variation in Fitness and Condition Facilitate Divergence in a Migratory Divide
TLDR
The results suggest that early arriving birds have disproportionate effects on population dynamics and allochrony and habitat isolation may act together to facilitate ongoing divergence in hybrid zones, and migratory divides in particular. Expand
Current selection for lower migratory activity will drive the evolution of residency in a migratory bird population
TLDR
The findings suggest that current alterations of the environment are favoring birds wintering closer to the breeding grounds and that populations of migratory birds have strongly responded to these changes in selection. Expand
Integrative tracking methods elucidate the evolutionary dynamics of a migratory divide
TLDR
This work integrates multiple approaches by using genetic, geolocator, and morphological data to investigate a migratory divide in hermit thrushes (Catharus guttatus), finding high genetic divergence between migratory groups indicates the divide is a region of secondary contact between historically isolated populations. Expand
Nesting phenology, mate choice, and genetic divergence within a partially migratory population of American Kestrels
TLDR
Results show that wintering strategy can have carryover effects on nesting phenology and mate choice in partially migratory populations, and environmental conditions (i.e. warmer winters) may facilitate kestrels remaining in or near temperate breeding areas and may lead to shifts in migratory behavior and nesting Phenology. Expand
Correlates of alternative migratory strategies in western bluebirds
TLDR
The results of this study suggest that social factors may influence migratory strategies in this partially migratory population of western bluebirds, and provide no support for the dominance or body size hypotheses, and only limitedSupport for the arrival time hypothesis in bluebirds. Expand
Individual variability and versatility in an eco-evolutionary model of avian migration
TLDR
The data reveal complex variation in songbird migration and suggest that selection can maintain variation in migration direction across short distances while enabling the spread of a novel strategy across a wide range. Expand
The Genetics and Evolution of Avian Migration
TLDR
Comparative studies suggest that migratory behavior has rapidly and independently evolved in different lineages, and genetic correlations among migratory traits and with other traits of the annual cycle are likely to play a major role in determining the rate and direction of evolutionary change. Expand
Individual variation in migratory behavior in a subarctic partial migrant shorebird
TLDR
Investigation of variation in migratory behavior of the partially migratory Eurasian oystercatcher population breeding in Iceland finds individuals were consistent inigratory strategy between years and there was no evidence of assortative mating by migratory strategy. Expand

HISTORICAL DIVERSIFICATION OF MIGRATION PATTERNS IN A PASSERINE BIRD
TLDR
The results show that the interruption of gene flow between migratory and sedentary populations is not necessary for the maintenance of such a polymorphism, and that even the most divergent migratory strategies of a bird species are susceptible to evolution in response to historical environmental changes.

Microevolution of migratory behaviour illustrated by the Blackcap Sylvia atricapilla: 1993 Witherby Lecture
TLDR
Observations on selection of morphological traits in Darwin's Finches on the Galapagos Islands and results of a 2-way selection experiment on migratory behaviour of Blackcaps Sylvia atricapilla¸ have indicated that substantial changes can occur within short periods. Expand
Links between worlds: unraveling migratory connectivity
TLDR
New advances in satellite telemetry, genetic analyses and stable isotope chemistry are now making it possible to determine the population and geographical origin of individual birds, and the relevance of understanding migratory connectivity to ecological, evolutionary and conservation issues is considered.

Avian migration phenology and global climate change

TLDR
The timing of arrival has advanced in relation to increasing winter temperatures in sub-Saharan Africa, whereas the timing of departure has advanced after elevated summer temperatures in Oxfordshire, demonstrating that migratory phenology is quite likely to be affected by global climate change.

Linking Breeding and Wintering Ranges of a Migratory Songbird Using Stable Isotopes
TLDR
It is shown that most birds wintering on western Caribbean islands come from the northern portion of the species' North American breeding range, whereas those on more easterly islands are primarily from southern breeding areas, indicating considerable population mixing with respect to breeding longitude. Expand
Linking winter and summer events in a migratory bird by using stable-carbon isotopes
TLDR
Habitat-specific isotopic signatures indicate that the quality of winter habitats occupied by American redstarts determines their physical condition and spring departure dates, which in turn result in variable arrival schedules and condition on temperate breeding grounds. Expand
Reproductive Effort, Molting Latitude, and Feather Color in a Migratory Songbird
TLDR
It is shown how reproduction in a migratory animal can influence both life history strategies (location of molt) and social signals (feather color) during subsequent periods of the annual cycle. Expand

TLDR
Analysis of data on brood patch, incubation periods, chick body size and recaptures of adults provides evidence of the existence of two distinct populations breeding annually on Baixo and Praia, out of phase by four to five months and overlapping in colony attendance during August and early September; on Vila only the cool-season population is present.

TLDR
Hydrogen isotopes may become a powerful tool for linking breeding and wintering grounds of neotropical migrant songbirds, as well as other migratory species moving between isotopically distinct regions. Expand
