THE COMMON SHELDEAKE. 493 



Shieldrake, and Sheldrake. I have adopted the latter 

 mode as being the one employed by Willughby,* who 

 adds, moreover, that it is so called on account of its "varie- 

 gated" plumage, in which sense the word "shelled" is 

 still cuiTent in the eastern counties of England. 



THE SHOVELLER. 



ANAS CLYPEATA.

The Shoveller is well distinguished among all the British 

 Ducks by the form and structure of its bill, which in old 

 birds is dilated near the extremity into a form approach- 

 ing that of a spoon, and is furnished with a fringe of 

 slender lamellae, resembling a comb. Towards the end 

 of the bill these are not conspicuous as long as the mouth 

 of the bird is closed, but along the narrower part they are 

 prominent under all circumstances. So singular an appa- 

 ratus obviously indicates that the habit of the Shoveller 

 is to sift water and mud for the sake of securing the insects 

 and worms which they contain. It resorts, therefore, to 

 the margins of fresh-water lakes, ponds, and ditches, and 

 is rarely seen at sea, nor does it ever dive after its food 

 in deep water, but frequently comes to land in quest of 

 slugs, snails, and worms. It is met with from time to 

 time in many parts of England, especially the eastern 

 counties, but is nowhere abundant. Its distaste for the 

 sea disqualifies it for inhabiting the Arctic Eegions ; con- 

 sequently it breeds in temperate countries, and flies farther
