 they are fairly common in the wet sections of Maine. Seven 

 to twelve eggs are laid, varying in color from pure white 

 to light green. The nests are placed in grassy spots close 

 to the water, and lined with a liberal amount of dark down.

 extensive range, including the temperate zones of both the 

 eastern and western hemispheres. It inhabits the British

 common ducks to be found in the market.

 on the Atlantic Coast in which it occurs in any numbers. 

 Along the Pacific Coast they are common residents of 

 California. jNIany of these ducks pass the winter about 

 the Gulf of Mexico, in Central America, and in the West
