172 HOODED SHRIKE. 
alist of the Birds of Andalusia, published by Dr. (Don 
Antonio) Machado, in 1854, no mention is made of this 
bird. The omission, however, loses much of its signi- 
ficance by not being noticed. M. Temminck remarks 
further that his specimens from Andalusia do not differ 
from those of Senegal. But Schlegel, writing m 1844, 
observes that the specimens killed in Spain and at the 
Cape of Good Hope are the same, while they differ 
both in size and colour from those brought from Senegal. 
This is also confirmed by Degland. But the Spanish 
specimens alluded to in both these instances were those 
procured from the south of Spain. There seems however 
to be two races or permanent varieties of this species, 
one inhabiting Senegal, and the other Abyssinia and the 
Cape of Good Hope, and found accidentally in Spain 
and France. 
The best account of this bird is given by Le Vaillant, 
in his “‘Histoire des Oiseaux d’Afrique,” from which I 
extract the following :— 
The feebleness of the wings of this Shrike prevents 
it from hunting on the wing, and it therefore contents 
itself with seeking under shrubs and among low plants 
caterpillars, spiders, and insects, which cannot escape 
from it by flight, as moths and grasshoppers do. This 
is another example of the manner in which Nature has 
adapted the forms of animals to their habits. The 
Ostrich, Cassowary, and other large birds, designed only 
to live upon the earth, have wings, but are unprovided 
with feathers fit to sustain them in the air, while their 
strong and massive feet fit them for the long journeys they 
are obliged to take. In the same manner the Mandiots, 
(Grebes,) which are formed to inhabit the water, have 
not only rudimentary wings, but their feet are placed 
so far back, that they cannot walk the slightest distance
