Summary The common mode of migration among Afrotropical birds is movement from tropical to temperate areas to breed usually coinciding with the onset of summer and the rainy season. The proportion of species that are migratory can be predicted with considerable accuracy from the average temperature of the coldest month of the year. Once this exceeds 20°C, 90% or more of breeding species will be non-migratory. The likelihood of any one species being migratory is strongly influenced by diet… 
The effects of climate change on the global migration of birds
Migration is one of the most spectacular wonders of the natural world but is increasingly threatened by large-scale environmental change. Migrants are key components of biological systems at higher
Bird species migration ratio in East Asia, Australia, and surrounding islands
The analyses revealed that the seasonality of ambient temperature, which represents the energy expenditure of birds, is the dominant factor in determining bird species migration.
The Australo-Papuan bird migration system: another consequence of Wallace's Line

The restriction of migration within Australo-Papua and the high variability of migratory pathways have important implications for the ecology and evolution of the Australasian avifauna.
Resource buffering and the evolution of bird migration
Evidence is presented that increased migrancy among North American passerines is associated with greater reliance on food resources that vary in abundance because they occur in microhabitats that are exposed both to consumers and environmental fluctuation, and that residency isassociated with use ofFood resources that occur in more ‘buffered’ microhab itats, and so are relatively invariant in abundance.
A Comparative Study of Species Diversity of Migrant Birds Between Protected and Unprotected Areas of the Hadejia-Nguru Wetlands, Nigeria
Among the most complex and fascinating behaviour in birds is their long, non-stop migration. Despite Hadejia-Nguru Wetlands (Ramsar site) being an important wintering ground for migratory birds,
Territoriality and density of an Australian migrant, the Buff-breasted Paradise Kingfisher, in the New Guinean non-breeding grounds
If demographic processes during the non-breeding season are found to limit populations in other Australo-Papuan migrants, the impending massive habitat loss in the Australasian and south-east Asian tropics may have devastating effects on many of these species.
Why do birds migrate? A macroecological perspective
Strong support is found for the hypotheses that birds move to breeding grounds to exploit a surplus in resources, preferring areas with harsh winters (presumably to avoid competition), and distribution during the non-breeding season seems driven by avoidance of harsh winters and connectivity to breeding Grounds.
The global ecology of bird migration: patterns and processes
This thesis is the first global macroecological analysis of bird migration, using a dataset on the geographical distributions of the world’s birds to mapped global patterns of migratory bird diversity, revealing strong spatial features and developing the first mechanistic, process-based model ofBird migration at the global scale.
Birds of Two Oceans? Trans-Andean and Divergent Migration of Black Skimmers (Rynchops niger cinerascens) from the Peruvian Amazon
This research documents the first documentation of a trans-Andes migration observed for any bird breeding in lowland Amazonia, and the first example of a tropical-breeding waterbird migrating out of the tropics to spend the non-breeding season in the temperate summer, the reverse pattern with respect to seasonality for austral migrants in general.
Long‐term declines of European insectivorous bird populations and potential causes
The findings suggest that the decline of insectivores is primarily associated with agricultural intensification and loss of grassland habitat, and the loss of both seed and insect specialists indicates an overall trend toward bird communities dominated by diet generalists.

It is inferred that species migrating between the temperate zone and the tropics have populations that are resource-limited throughout the year, and that these migrants impose year-round population limitation on the members of the resident temperate and tropical bird communities.

Austral migrants are species that breed in temperate areas of South America and migrate north, towards or into Amazonia, for the southern winter, and the austral system represents a third major migration system, in the sense that the term has been applied to Northern Hemisphere temperate-tropical migration.

Relationship between migration and latitude among west European birds
In western Europe, the number of bird species present in summer remains fairly constant, but the number present in winter decreases steadily with latitude, reflecting the greater withdrawal of species from northern latitudes in winter.

Passerine Migration between the Palaearctic and Africa
Migration is one of the possible responses by which an organism can react to changes in its environment, and birds, among others, have responded to this evolutionary challenge.
