DD The GREATER COVERTS, \tectrices secundcc, Linn.] 

 the feathers that lie immediately over the quill feathers and 

 the secondaries.

 Linn.] the largest feathers of the wings : they rise from the 

 first bone.

 darice, Linn.] those that rise from the second bone.

 second bone, at the elbow joint, forming a continuation of 

 the secondaries, and seem to do the same with the scapulars, 

 which lie over them. These feathers are so long in some of 

 the Scolopax and Tringa genera, that when the bird is fly- 

 ing they give it the appearance of having four wings.

 rise from the shoulders, and cover the sides of the back. 



P COVERTS of the TAIL, \uropygivm. Linn.] These 

 feathers cover it on the upper side, at the base.

 from the vent, or anus, to the tail underneath.

 the eye.
