Mr. W. L. Sclater on Birds collected 
threes, and inhabits more or less bushy country; it feeds 
largely on insects, for which it is observed searching in the 
trees and shrubs as well as on the ground. The cry is clear, 
somewhat loud, and generally of two notes ; the flight is 
slow and jerky, the white on the wings and tail shewing 
conspicuously. It is rather a wary bird, and cannot always 
be approached within shot. 
The soft parts of the adult are :—Irides hazel; bill, legs 
and toes blackish.] 
383. Irrisor viridis.

[“ Kakelaar” of the Colonists. 
I have notes of this species from the Knysna only. It is 
always seen in small parties of about half a dozen individuals, 
and spends its time searching the trunks and larger limbs 
of the trees for insects and grubs. It can often be seen 
hanging head downwards on the under side of the branches 
examining the interstices of the bark. It has a loud 
clattering cry of many syllables rapidly repeated, accom¬ 
panied by a see-saw movement of the body, the head being 
well thrown back each time, and likewise the tail. I have 
on several occasions seen the birds when calling face one 
another on a horizontal branch, their continual bowing to 
each other being very comical. The flight is undulating and 
never long sustained, the tail being widely spread, shewing 
clearly the white spots on it and on the wings. The species 
will often pitch on the side of the trunk of a tree after the 
manner of a Woodpecker. 
The soft parts of the adult are :—Irides dark brown; bill, 
legs and toes coral-red. 
In the young :—Irides much darker brown ; bill black ; 
legs and toes pink-brown.] 
383 a. Irrisor erythrorhynchus.
