sections: the Diurnal, whose eyes are on the sides of 
the head, wings point-

scales, as the Vultures, 
Kites, Hawks, Falcons,

Climbers.’** — These 
Birds have no other 
exclusive peculiarity 
than the pairing of the 
toes, two being turned 
forward and two back- 
ward. Usually it is the 
outer toe which pairs 
with the hind toe; in 
the Trogons, it is the 
inner one. They are 
not musical, and only 
ordinary fliers. They 
feed on Insects or 
fruit. The majority 
make nests in the hol- 
lows of old trees; but 
the Cuckoos lay in the 
nests of other Birds. —
