Winds and barriers shape zigzagged trans-African migrations of Canarian Eleonora’s falcons

A research team led by Doñana Biological Station – CSIC studied how wind fields and geographical barriers shape the trans-African migrations of Eleonora’s falcons between the Canary Islands and Madagascar
The results show that falcons zigzag across Africa because they maximize wind support through oppossing wind fields, across open ocean and across the Sahara, and then compensate for those displacements through weak or favourable wind fields
