Habits. “It is found in the same poplar and alder bushes as 
the Babax, but also comes up quite close to the villages. It has 
the characteristic habits of a Babbler to a marked degree, roves 
about in parties of eight or more individuals, chatters most noisily, 
uttering its fluty eall of ‘ Whoh-hee Whoh-hee,’ is always on the 
move, scampering along the branches, seldom showing itself, and 
flying very low across a clearance to the next cover.’ (Wadidell).
