Families of geese fly together
Animal: white-fronted geese
In contrast to songbirds, families of geese stay together during their first migration and often for even longer. Scientists suspect that parent geese pass on their knowledge about bird migration and feeding places to the young animals. The route and time of migration are very constant among individual birds. However, it has not yet been established whether the young geese select the same flight path and the same time for their journey as their parents after separating from them.
The Icarus researchers want to observe the flight paths of geese families throughout their entire lifetimes. They are attaching transmitters to white-fronted geese (Anser albifrons) in their breeding grounds and comparing the movements of family members on their first migratory journeys. They are also exploring which factors influence the timing of migration and which animals lead the flights. They also want to find out when and how young geese separate from their parents and how the family members find one another again after separation. The results will help to provide white-fronted geese with more effective protection.
