The migratory behavior of adult red-backed shrikes has already been researched quite well, but about young shrikes we still know very little. Last year, a select group of 20 young shrikes in good condition were equipped with a data logger that records the migration route. Do these inexperienced animals immediately take the same route [as adults] or should they still learn?
