However, migration is energetically costly, so migrating animals must prepare themselves by increasing their energy stores...

We tested whether juvenile spring-spawning Atlantic herring, caught in the western Baltic, use a sun compass for orientation just before they start leaving...

Bluefin tuna exhibit yearly roundtrip migrations of 5000–16,000 km between their feeding and spawning grounds ( Bestley et al., 2008 ; Patterson et al., 2008 , 2018 ; Willis et al., 2009 ).

...Joely G. DeSimone; Bret W. Tobalske; Creagh W. Breuner ABSTRACT Migration allows animals to use resources that are variable in time and/or space, with different migratory strategies depending on the predictability of resource variation. When food varies seasonally, obligate migrants anticipate...

... orientation responses in animals are often weak and difficult to elicit experimentally. A possible explanation is that the magnetic compass is ‘noisy’ and cannot acquire precise magnetic information over short time periods. Magnetoreception Orientation Migration Signal-to-noise Numerous...

.... The headings adopted by these navigationally naive fish coincided remarkably well with the direction of the juveniles' migration inferred from historical tagging and catch data. This suggests that the large-scale movements of pink salmon across the North Pacific may be driven largely by their innate use...

Extensive studies of migration in the iconic monarch butterfly Danaus plexippus have revealed that vision plays a crucial role in migratory orientation. Differences...

To perform long-distance dispersal, flies must actively maintain a straight compass heading through the use of external orientation cues, such as those derived from the sky.

As a result, it is hypothesized that migrant and resident birds use environmental cues differently to prepare to breed and that there is adaptive...
