One of the chief characters in this genus is the elongated crest, 

 with white bases to the feathers which form a more or less 

 concealed spot. The bill is small and pointed. The wing is 

 rounded, the second, third, fourth, and fifth primaries longest 

 and almost equal, the first about equal in length to that of the 

 tenth. The tail is long and square at the tip and about equal in 

 length to that of the wing. The hind toe and claw are about half 

 the length of the tarsus. Coloration : niale and female similar.
