months of April and October. It associates with the small sandpipers along the shores of the 

 baj's and estuaries, and though apparently feeding on the same food, it picks it up on the 

 surface of the ground instead of probing in the mud or sand. — C.

Hak — All of North America. The sea-coasts of nearly all countries of the world. 



The black-bellied or Swiss plover I found moderately abundant in Minnesota, and also sparingly 

 on the sand spits and beaches along the Straits of Fuca, in Washington Territory. In the 

 latter vicinity I obtained several specimens in the early part of March, 185G. 



Owing to the general mildness of the winters in the last-mentioned locality, a few generally 

 remain throughout the season, where, in company with the turnstone and the active little three- 

 toed sandpiper, they may, any fine day during the colder months, be found industriously seeking 

 their favorite food at the edges of the retiring waves. In the spring and fall they are quite 

 common in the San Francisco markets. — S. 



The Swiss plover seems to be a resident bird in small numbers, as I shot j^oung birds in July 

 near the mouth of the Columbia river, together with the young of several other species of shore 

 birds. During the coldest winter weather*! also observed them in greater numbers, but never 

 in flocks of more than a dozen. — C.
