Males migrate farther than females in a differential migrant: an examination of the fasting endurance hypothesis

  author={Elizabeth A. Gow and Karen L. Wiebe},
  journal={Royal Society Open Science},
Patterns of migration including connectivity between breeding and non-breeding populations and intraspecific variation in the distance travelled are important to study because they can affect individual fitness and population dynamics. Using data from 182 band recoveries across North America and 17 light-level geolocators, we examined the migration patterns of the northern flicker (Colaptes auratus), a migratory woodpecker. This species is unusual among birds because males invest more in…

Differential migration and the link between winter latitude, timing of migration, and breeding in a songbird

Evaluated differential migration of Savannah sparrows breeding on Kent Island in the Bay of Fundy, New Brunswick, Canada in relation to sex, age, and body size found benefits for males of early arrival on the breeding grounds may have contributed to their wintering farther north than females.

Effects of Spring Migration Distance on Tree Swallow Reproductive Success Within and Among Flyways

During migration, animals may experience high rates of mortality, but costs of migration could also be manifested through non-lethal carry-over effects that influence individual success in subsequent

Sex-Specific Spatiotemporal Variation and Carry-Over Effects in a Migratory Alpine Songbird

Overall, the results indicate: (1) sex-specific flexibility in migration strategies that carry-over to and from the reproductive period, and (2) spring staging areas may be a critical component of the annual life-cycle for alpine breeding larks.

Local recruitment in Northern Flickers is related to environmental factors at multiple scales and provides reproductive benefits to yearling breeders settling close to home

ABSTRACT Natal dispersal and local recruitment are affected by factors both intrinsic and extrinsic to juveniles and may affect fitness. Understanding the relationship between dispersal and

A general theory of avian migratory connectivity.

This model provides a strong basis for exploring additional processes underlying the ecology and evolution of migration, but also a framework for predicting how migration impacts local adaptation across seasons and how environmental change may affect population dynamics in migratory species.

Migratory patterns and connectivity of two North American grassland bird species

By providing the most extensive examination of the nonbreeding movement ecology for these two North American grassland bird species to date, this work refine information gaps and provide key insight for their management and conservation.

Neither sex appears to benefit from divorce within migratory Northern Flickers consistent with accidental loss and bet-hedging

ABSTRACT Divorce is widespread among species of birds and may either be an adaptive strategy to secure a better mate or territory or be a nonadaptive result of a failure to maintain the pairbond. I

Linking Peregrine Falcons' (Falco peregrinus) Wintering Areas in Peru with Their North American Natal and Breeding Grounds

Abstract. Identifying migratory raptors' wintering areas and migration routes is an essential part of predicting their responses to habitat and climate change throughout their annual cycles, and

Differential Migration of Birds: Diversity and Inconsistency

A brief review of the intrapopulation differences in bird movements that are attributed to the phenomena of differential migration is given, and the main hypotheses put forward to explain the



Intraspecific variation in migratory pattern of a partial migrant, the blue tit (Parus caeruleus): an evaluation of different hypotheses

A local population of Blue Tits was studied in southern Sweden and it was concluded that, among juveniles, more than 40% of the females and a significant proportion of the males migrated, while considerably fewer adult females and virtually no adult males did so.

Migratory Connectivity and Rate of Population Decline in a Vulnerable Songbird

The results suggest that the strength of migratory connectivity should be an important factor when making resource-allocation decisions for the management and conservation of migratories species.

Dramatic intraspecific differences in migratory routes, stopover sites and wintering areas, revealed using light-level geolocators

The suggestion that divergent migratory behaviour could contribute to reproductive isolation between migrants, advance the understanding of their non-breeding ecology, and are integral to development of detailed conservation strategies for this group are supported.

Continent-wide tracking to determine migratory connectivity and tropical habitat associations of a declining aerial insectivore

The results show that differences in wintering location and habitat do not explain recent trends in breeding population declines in this species, and instead northern populations may be constrained in their ability to respond to climate change.

Partial migration in expanding red deer populations at northern latitudes – a role for density dependence?

It is suggested that a combination of avoidance of competition in high density winter ranges, social fencing during summer in addition to the forage maturation and predation risk avoidance hypotheses, is needed to explain migration patterns of northern ungulates.

The body-size hypothesis is re-articulated in the context of tropical altitudinal bird migration, focusing explicitly on how limited foraging opportunities and differences in individual condition affect fasting ability during torrential rains.

Female-biased obligate strategies in a partially migratory population.

The results provide strong support for the 'Arrival Time' hypothesis for partial migration in the autumn and suggest the co-occurrence of obligate autumn migrants, winter movements and sedentary individuals within a single population.

Sex- and context-dependent migration in a pond-breeding amphibian.

It is demonstrated experimentally that migration can be a plastic response influenced by both local density and gender, suggesting important sex-based trade-offs of migration.

Life history correlates of alternative migratory strategies in American Dippers.

Because migrants obtained no fitness benefits by moving to seasonal breeding territories, the data are consistent with the hypothesis that migration could evolve in sedentary populations if competition for limited resources forces some individuals to seek breeding opportunities outside their initial range.

Gulls can change their migratory behavior during lifetime

Age-related changes in individual migration habits in lesser black-backed gulls, Larus fuscus are examined, showing a latitudinal cline in age structure across the wintering range, with adults and gulls in their fi rst breeding year wintering closer to the breeding grounds.
