the ‘ antelope ’ unfolded his broad black-tipped 
wings and flapped off, revealed at length as a 
whooping (white) crane.” 
Another very remarkable species is the 
Crowned Crane. This is an African species, and 
takes its name from the tuft of curiously modified 
feathers on the top of the head. The coloured 
plate gives a good idea of its general appearance. 
The Seriema 
This is a very hawklike-looking bird ; indeed, 
by some ornithologists it has been regarded as 
closely allied to the Hawks and Eagles, and 
more especially to the Secretary-bird. Really, 
however, it is a very ancient kind of crane. 
The Trumpeters, the Courlans, the Kagu, 
and the Sun-bittern are other ornithological 
puzzles. Concerning the precise affinities of these 
birds much is yet to be learnt; they are, how- 
ever, undoubtedly related to the Cranes. The 
last mentioned is a small bird, with wonderfully beautiful wings, which it displays with great 
effect to its mate during the courting-season.

of an exceedingly 
ancient type, and are in many 
ways besides v'ery interesting. 
Both are common British birds. 
The greater part of their lives 
is spent upon the water, and 
to suit this aquatic existence 
their bodies are specially 
modified. One of the principal 
features of this modification 
is seen in the position of the 
legs. These, by a shortening 
of the thigh-bones in the 
grebes, leav^e the body so far 
back that when the bird walks 
the body is held vertically. 
With the divers walking has 
become an impossibility, and 
they can only move on land 
on their bellies, pushing 
themselves along with the 
feet. Both grebes and divers
