listener, hopping and creeping about the dense underwood, and peer 
ing through the crevices at its supposed enemy; the tail is then 
carried erect, like that of the English Wren, and the bird is in almost 
constant motion ; it has also a loud and oft repeated “ chucking” 
note, which it uses as a call to its mate during the breeding months. 
Its food consists entirely of small insects.” 
Mr. Andersson writes :—“ This species is pretty common in the 
neighbourhood of the Okavango River, and is also not uncommon 
in Damara Land proper; but I did not meet with it in Great Na- 
maqua Land. It is avery tame bird, and hunts slowly and with 
great care, examining alike, in quest of insects, both thickets and 
the largest trees ; it generally carries its wings slightly drooping 
when thus engaged, and its tail raised at an angle of 45°.” Senor 
Anchieta has met with it at Biballa in Mossamedes as well as at 
Humbe on the River Cunene.

Le Vaillant first described this bird as the ‘ Olivert’ from Outeni- 
qualand, and Victorin obtained it in the Karroo. Mr. W. Atmore 
has sent us specimens from Blanco, near George. Mr. Ortlepp has 
met with it near Colesberg, where he says the species is called
