Reticulate - refers to the way in which scales of the legs are positioned; 

 in this case, they do not overlap but rather meet each other as in 

 the mesh of a net or as in the lines around the knuckles on a 

 person's hands (Fig. 13) .

 on the tarsus. 



Scutellate - refers to the way in which scales of the legs are positioned, 

 in this case overlapping as in shingles; see reticulate (Fig. 13). 



Secondary (or secondaries, plural) - those "flight" feathers that attach 

 to wing bones between the wrist and elbow (see Fig. 8). These are 

 numbered from the wrist inward. 



Speculum - in some ducks, that part of the wing, usually feathers of the 

 inner secondaries and greater secondary coverts, that in coloration, 

 strikingly contrasts with the remainder of the wing (Fig. 14).
