metadata.name: dc.description.abstract
metadata.value: Migratory birds use several different sources of orientation information. They
  have at least three compass systems based on different cues: the sun and polarized light, the stars and their constellations, and the geomagnetic field. The
  concurrent information obtained from these three compasses is redundant,
  therefore the compasses need to have a hierarchy and must be calibrated relative to each other. One of the compasses should dominate the others, or some
  orientation cue should be used to calibrate the remaining compass systems.
  Results of experiments on a variety of songbird species demonstrate that while
  astronomical cues calibrate the magnetic compass during the pre-migratory
  period, strategies used during the migratory period are more diverse. In the
  present review, we analyze the results of all crucial cue-conflict studies, mostly
  performed in nocturnal songbird migrants; we also try to understand why some
  migratory species calibrate their magnetic compass on sunset cues while others use the geomagnetic field or stars as a primary cue source, and we examine
  why the previous hypothesis could not explain the findings of all cue-conflict
  experiments
