New migration pattern described for ringed plovers: old theories fail as explanation

When finished breeding in south Sweden (study population is at Ottenby), males and females ringed plover depart to different wintering areas. But males go further south, to winter mainly on the Iberian peninsula, while females stay on average 800 km nearer to the breeding site. In birds it is usually the other way around, that males winter closer to the breeding site, often explained by the need of the territory-defending sex (usually male) that have a need to arrive early on the breeding ground and therefore stay the winter closer. In this new study, Linus Hedh and Anders Hedenström describe a new migration pattern, and add a new model that may explain the new findings. Read more at
