FAMILY XL. AVOCETS AND STILTS (RECUR VIR6sTRID^) 



This is a small family (11 species) of extremely long-legged, 

 long-necked, slender-billed, wading birds. Their bills are long 

 as well as slender, and have more or less of an upward bend. 

 The Avocets swim with great ease, and are tame birds, gener- 

 ally found in flocks. Their food consists of water-insects, and 

 crustaceans, which they obtain mainly in shallow water, swing- 

 ing the bill from side to side like a man mowing. The Stilts 

 are much like avocets, but have even longer legs, and are not 

 so well fitted for swimming; so. tliough their food consists of 

 the same kind of insects and crustaceans, they obtain nearl}'- 

 all of it by wading.
