Today my post is about a little bird that I enjoy watching run on the sandy beach back and forth from the ebbing surf, looking for the small invertebrates or any of their favorite food. They are very fast runners and they are sometimes a bit difficult to photograph because of their constant moving.
The Sanderling (Calidris alba) is a small wading bird. It is a circumpolar Arctic breeder, and is a long-distance migrant, wintering south to South America, South Europe, Africa, and Australia. It is highly gregarious in winter, sometimes forming large flocks on coastal mudflats or sandy beaches.
It is somewhat unlike other sandpipers in appearance, which has led to the suggestion that it should be placed into a monotypic genus Crocethia. A more recent review (Thomas et al., 2004) indicates, however, that the sanderling is a fairly typical “stint” or small sandpiper and should be separated from the large knots with its closest relatives in a distinct genus.
This bird is similar in size to a dunlin, but stouter, with a thick bill. It shows a strong white wing-bar in flight, and runs along the sandy beaches it prefers with a characteristic “bicycling” action of its legs, stopping frequently to pick small food items. It eats small crabs and other small invertebrates. In spring, birds migrating north from South America consume large numbers of horseshoe crab eggs in the Delaware Bay area.
