Colies have a bad reputation among the settlers, 
because they steal ripe fruit. The plumage of the cock 
and hen are almost identical. The colies dart about in 
flocks of six, eight, or ten. The Masai use the skin of 
the mouse-bird to decorate their heads. 
A Shrike {Lanius humeralis), very common around Nairobi; 
it is very fond of sitting on a prominent branch of a dry, 
leafless, prickly acacia. In the vicinity of the railway it 
prefers to perch on a telegraph wire. This shrike has the 
same habits as the English butcher bird and keeps a larder. 
Shrikes are sure to attract attention. The Scarlet- 
bellied Bush-Shrike is common in the thorn-orchards of 
the Sudan; it has a flute-like note, usually uttered 
from a thorn bush. The black and white shrike, like 
our butcher bird, keeps a larder.
