PMID: 37689066
Great reed warblers, Acrocephalus arundinaceus, and great snipes, Gallinago media, exhibit a diel cycle in flight altitudes-flying much higher during the day than the night-when performing migratory flights covering both...

PMID: 36457000
Background: Long-distance migratory birds undergo complex annual cycles during which they must adjust their behaviour according to the needs and conditions encountered throughout the year. Yet, variation in activity throughout...

Curr Biol
. 2021 Jul;
31(15):3433-3439.e3.
PMID: 34197730
Several factors affect the flight altitude of migratory birds, such as topography, ambient temperature, wind conditions, air humidity, predation avoidance, landmark orientation, and avoiding over-heating from direct sunlight. Recent tracking...

PMID: 33958477
Billions of nocturnally migrating songbirds fly across oceans and deserts on their annual journeys. Using multisensor data loggers, we show that great reed warblers () regularly prolong their otherwise strictly...

PMID: 31534672
The arctic tern completes the longest known annual return migration on Earth, traveling between breeding sites in the northern arctic and temperate regions and survival/molt areas in the Antarctic pack-ice...

. 2018 Nov;
188(4):1011-1024.
PMID: 30386941
Stopovers play a crucial role for the success of migrating animals and are key to optimal migration theory. Variation in refuelling rates, stopover duration and departure decisions among individuals has...

PMID: 30205072
Billions of animals are adapted to a travelling life, making regular return migrations between more or less distant living stations on Earth by swimming, flying, running or walking (Figure 1)....

. 2018 Aug;
87(6):1698-1708.
PMID: 30101481
Migration usually consists of intermittent travel and stopovers, the latter being crucially important for individuals to recover and refuel to successfully complete migration. Quantifying how sickness behaviours influence stopovers is...

PMID: 29992024
Birds use different compass mechanisms based on celestial (stars, sun, skylight polarization pattern) and geomagnetic cues for orientation. Yet, much remains to be understood how birds actually use these compass...

PMID: 28343237
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 pattern, behaviour and energy expenditure. Such...
