Description

There are good biological reasons for some birds to breed in one part of our planet and spend the rest of the year at another. Long-distance migrating shorebirds breed in the Arctic combine their reproductive activities on the tundra with a life on soft-sediment seashores, flying as far south as the Sub-Antarctic. Such shorebirds show a range of trophic specializations and among them the red knot Calidris canutus combines visual hunting for surface-living arthropods on the tundra with probing for hard-shelled prey on intertidal sedimentary flats. As suitable habitats are rare and widely dispersed across the globe, the long migration flights of red knots may be considered a consequence of their ecological specialization.Enabled by the new availability of very small solar-powered satellite tags, in this study we analysed the complete tracks of eight red knots C. c. piersmai, marked in February 2018 in coastal NW Australia, back and forth to the tundra breeding grounds on the New Siberian Islands, Russia. We will try to illuminate the critical features of this remarkable annual cycle in comparisons with what we know of the subspecies of red knots in other parts of the world, and review evidence for cross-seasonal interactions.
