forked, forficate. A cuneate tail is the exact opposite to one 
forficate. 
The tarsus, often called the “leg,” extends from the base of 
the toes to the first joint above, and in a majority of birds is 
unfeathered. If without scales in front (unless near the bot- 
tom) it is ‘‘ booted,” or if with scales, scutellate. (If covered 
with very small scales which do-not overlap one another, it is 
reticulate; or it may be granulated as in the Fish Hawk.) 
The following is a vocabulary of several other descriptive

Crown, top of the head (usually above the eye). Eye-patch,

Except where there are indications to the contrary, the 
‘“upper parts” generally include the upper surface of the
