The Crown, 2. 
The Nape, 3. 
Upper and under mandibles, or chaps, 4-4. 
Chin, 5. 
The interscapular region, 6. 
Tail coverts; these feathers cover the tail at its upper side or 
base, 7. 
Lesser Wing Coverts, 8-S-8-8, — (teclrices primes, Lin¬ 
naeus .)— these are small feathers that lie in several rows 
on the bones of the wings. 
Greater Wing Coverts, 9-9-9-9 ,—('teclrices secundce, Lin.) 
—the feathers that lie immediately over the quill feathers 
and the secondaries. 
The Scapulars, 10-10-10, or those feathers which take their 
rise from the shoulders, and cover the sides of the back. 
The Secondaries, 11-11-11-11, or secondary quills,— fsecon¬ 
daries, L,inn .)—those that rise from the second bone. 
The Tertials, 12-12—12-12-12. — These also take their rise 
from the second bone at the elbow joint, forming a con¬ 
tinuation of the secondaries, and seem to do the same 
with the scapulars which lie over them. These feathers 
are so long in some species of the Scolopax and Tringa , 
that when the bird is flying, they give it the appearance 
of having four wings, as in the figure we have given. In 
nearly all other species they are but a little longer than 
the Secondaries. 
The Primaries, or Primary Quills, 13-13-13-13-13,— 
(primores, Linn .)—the largest feathers of the wing; they 
rise from the first bone.

The Under Coverts are those which line the inside or un¬ 
der surface of the wings.
