Habits. According to Davison/fickell's Spotted Babbler is found 

 in small parties haunting jungle, both forest- and more open

 whereas the Nagas describe the last bird as frequenty hunting for 

 food amongst the fallen leaves. 



Genus STACHYRIS Hodgson, 1844. 



This genus is very close indeed to the last, differing principally 

 in its smaller, more pointed, bill, which has, however, the culmen 

 gently curved throughout in the same manner.
