Shorebirds

Sub Categories

The red knot, Calidris canutus, is an example of a longdistance migratory shorebird. It has been the subject of extensive research worldwide including studies on its breeding cycle, winter ecology, and stopover sites. It is a typical representative of high Arctic shorebirds and is, therefore, a good indicator species for the whole group. As one of nature’s most prodigious travelers, it excites the interest of wildlife enthusiasts, scientists, and conservationists worldwide. For this reason its migration system is among the best known of all shorebirds, although many mysteries still remain.

Figure 4.1. Avian biodiversity in different regions of the Arctic. Charts on the inner circle show species numbers of different bird groups in the high Arctic, on the outer circle in the low Arctic. The size of the charts is scaled to the number of species in each region, which ranges from 32 (Svalbard) to 117 (low Arctic Alaska).

Worldwide distribution of the six recognized subspecies of the red knot

Worldwide distribution of the six recognized subspecies of the red knot [2]. All breeding areas (dark purple shading) are on high Arctic tundra where adults spend June–July. After their long-distance migrations, they spend the non-breeding season (August–May) mainly in intertidal, soft-sediment habitats (red dots, which are scaled according to population size).
