Migratory birds regularly perform impressive long-distance flights, which are timed relative to
the anticipated environmental resources at destination areas that can be several thousand …

The use of accelerometers has become an important part of biologging techniques for large-
sized birds with accelerometer data providing information about flight mode, wing-beat …

Seasonal bird migration may provide energy benefits associated with moving to areas with
less physiologically challenging climates or increased food availability, but migratory …

Migratory flight requires birds to maintain intensive aerobic exercise for many hours or days.
Maintaining O2 supply to flight muscles is therefore important during migration, especially …

Seasonal migration is a complex and variable behaviour with the potential to promote
reproductive isolation. In Eurasian blackcaps (Sylvia atricapilla), a migratory divide in central …

Populations of migratory bird species have suffered a sustained and severe decline for
several decades. Contrary to non-migratory species, understanding the causal mechanisms …

Migratory birds seasonally increase fat stores and the capacity to use fat to fuel long-
distance migratory flights. However, lean mass loss also occurs during migratory flights and …

Aim Millions of birds take to the air for nocturnal migrations. Although it is widely recognized
that migrants generally depart after sunset, nightly migration timing and their dependence on …

In a seasonal world, organisms are continuously adjusting physiological processes relative
to local environmental conditions. Owing to their limited heat and fat storage capacities …

The onset of spring migratory behavior in birds is thought to be controlled by a rigid
endogenous schedule as a result of selection to time migration with environmental …
