|Western Sandpiper. San Elijo Lagoon, Cardiff-By-The-Sea, California. August 17, 2014. Greg Gillson.|
Map of range of Western Sandpiper throughout the year.
Bill long (longer than head) and drooped at the tip, and black legs identify Western Sandpiper from among the smaller shorebirds of the West. Baird's Sandpiper and the rare Semipalmated Sandpiper, and the larger Dunlin are similar.
The Western Sandpiper above shows the partial webs between toes, called "semipalmated."
The scientific name of Western Sandpiper is Calidris mauri, given in 1838 by Charles Bonaparte for his friend Ernesto Mauri. Think how different European history might have been had Napoleon taken up ornithology like his nephew Charles.
