Across a range of organisms, related species or even populations of the same species
exhibit strikingly different scales and patterns of movement. A significant proportion of the …

The East Asian-Australasian Flyway supports the greatest diversity and populations of
migratory birds globally, as well as the highest number of threatened migratory species of …

Migration, broadly defined as directional movement to take advantage of spatially distributed
resources, is a dramatic behaviour and an important component of many life histories that …

Migratory birds track seasonal resources across and between continents. We propose a
general strategy of tracking the broad seasonal abundance of resources throughout the …

We outline a general scheme for migration that applies across taxa, incorporates the several
varieties of migration, and includes all levels of biological organization, from genes to …

Bar-headed geese (Anser indicus) fly at up to 9,000 m elevation during their migration over
the Himalayas, sustaining high metabolic rates in the severe hypoxia at these altitudes. We …

Seasonal migration is a taxonomically widespread behaviour that integrates across many
traits. The European blackcap exhibits enormous variation in migration and is renowned for …

Migratory divides are contact zones between populations that use different routes to
navigate around unsuitable areas on seasonal migration. Hybrids in divides have been …

Migratory divides are contact zones between breeding populations that use divergent
migratory routes and have been described in a variety of species. These divides are of major …

Migratory animals move up to thousands of kilometers every year [1]. Losses of migration (ie,
migratory drop-offs) occur when individuals of a migratory species stop migrating and …
