Whether avian migrants can adapt to their changing world depends on the relative importance of genetic and environmental variation for timing direction migration. In classic series field experiments migration, A. C. Perdeck discovered that translocated juveniles failed reach goal areas, whereas adults performed ‘true-goal navigation’. His translocations > 14 000 common starlings ( Sturnus vulgaris ) suggested mechanisms guide into a population-specific direction, i.e. ‘vector However, alternative explanations involving social learning after release in could not be excluded.

What if your life depended on finding a place you’ve never been—without GPS device, guide, or any way of knowing where to go? For young songbirds, this is the reality their first migration. While once puzzled researchers studying bird migration, advances in field have since uncovered that many songbirds rely an inherited genetic program guide remarkable solo journeys. Today, most widely accepted theory explaining how birds species migrate solitary and do not follow experienced conspecifics find wintering grounds ‘clock-and-compass’ concept. According concept, naïve migrants certain compass direction for pre-defined period. In simplest case, when runs out, they themselves species-specific non-breeding range. However, recent research suggests process might be significantly more complex. New data indicate first-time may complete map but rather system beacons. This could based, example, geomagnetic cues other help first-year navigate location along migration route. To date, significant body evidence has been gathered revise classic ‘clock compass’ program. It likely (although perhaps all) are capable varying degrees control based innate information. The question what sources use precise remains open further investigation.
