Global movement patterns of migratory birds illustrate their fascinating physical and
physiological abilities to cross continents and oceans. During their voyages, most birds land …

For centuries, humans have been fascinated by how migratory animals find their way over
thousands of kilometres. Here, I review the mechanisms used in animal orientation and …

Geolocator accuracy varies, depending on bird behavior, geographic location, habitat, and
weather (Fudickar et al. 2012, Lisovski et al. 2012). Ground truthing at multiple sites prior to …

Background Songbirds following distinct migration strategies (eg long-vs. short-to medium-
distance migrants) often differ in their speed of migration during autumn and, thus, are …

Faster migration in spring than in autumn seems to be a common pattern in birds. This has
been ultimately explained by seasonally different selection pressures. Variation in migration …

Abstract Aim In the Northern Hemisphere, bird migration from the tropic to the temperate
zone in spring is thought to proceed at a rate determined in large part by local phenology. In …

In birds, accumulating energy is far slower than spending energy during flight. During
migration, birds spend, therefore, most of the time at stopover refueling energy used during …

The annual 29 000 km long migration of the bar-tailed godwit, Limosa lapponica baueri,
around the Pacific Ocean traverses what is arguably the most complex and seasonally …

An estimated 17% of migratory bird species are threatened or near threatened with
extinction. This represents an enormous potential loss of biodiversity and cost to human …

In many migratory birds, males precede females during migration and arrival at the breeding
sites. Three proximate mechanisms are proposed to explain this phenomenon of protandry …
