  2. 1. Stopover behaviour in migratory songbirds: timing, orientation and departures

    Author : Sissel Sjöberg; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; flight duration; orientation; departure timing; stopover behaviour; stopover duration; flight behaviour; reverse migration; route choice; compass calibration; passerines; Bird migration;

    Abstract : Songbird migrants use stopovers between flight bouts to rest and refuel for the upcoming flights. Behaviours affecting where, when and how long to stay at stopover sites will affect how successful the overall migration will be, which has significant consequences for the overall fitness and mortality of the birds.

  4. 2. Ecology and evolution of large-scale bird migration patterns : A natural history and comparative study of the migration in common and little ringed plovers

    Author : Linus Hedh; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ringed plover; leap-frog migration; migration speed; migration process; light level geolocator; migration;

    Abstract : Migration distance and seasonal redistribution patterns may vary between and within bird populations. A common pattern is leap-frog migration, in which northerly breeding populations migrate farther and winter south of more southerly breeding populations. READ MORE

  5. 3. Individual consistency in bird migration

    Author : YANNIS VARDANIS; Evolutionär ekologi; []
    Keywords : bird migration; telemetry; bird ringing; individual consistency; repeatability; site fidelity; routes; timing; annual cycle; meta-analysis;

    Abstract : Slight differences, which appear in the individual animals of the same species and population have been recognised and appreciated ever since Darwin. These consistent intra-specific differences in animals have been considered very important because they are often inherited, and thus, provide the basic material for evolution to act on. READ MORE
