Family CHARADRIDAE. 
This family is divided by Bonaparte into the three sub-families Oedicneminae, Charadrinae, 
and Cursorinae ; but as the first and last are not represented in North America, there is no 
occasion to present them here. They are readily distinguished from the Charadrinae by well 
marked characters. 
The characters of the Charadrinae are sufticiently well expressed in the diagnosis of the 
family already given. The wings when folded reach beyond the tail. The head is very large, 
the neck short, and nearly as thick as the head. The bill in size and shape has, in some 
instances, quite a close resemblance to that of the doves. The legs, as a general rule, have no 
hind toe, except in Squatarola, The middle and outer toes are connected at the base by a 
membrane.
