COLLARED PRATINCOLE. 475 



In the young bird the clove-brown feathers of the back, 

 and the wing-coverts, the secondaries and tertials, have 

 pale reddish brown margins ; the tail-feathers shorter, and 

 much less forked ; throat pale brown, the crescentic collar 

 indicated by dark brown spots; breast varied with two 

 shades of brown ; belly, and under surface of the body, 

 and tail-feathers, greyish white. 



Females are said to resemble the males. The whole 

 length of an adult bird is near ten inches. From the 

 carpal joint to the end of the first quill -feather, seven 

 inches. 



The outline below represents the breast-bone of the 

 Pratincole. The double emargination on each side of the 

 keel will be found to resemble the breast-bones of the 

 Bustards and Plovers, and is quite different from those 

 parts in the Swallow tribe, as will be seen by a reference 

 to the breast-bone of the Swift, at page 279.
