THE LIVING ANIMALS OF THE WORLD 
by Bates in the interior of Brazil. As its 
name implies, it is of a deep hyacinthine 
colour, relieved by a bare patch of pure 
white skin round the eyes. It feeds on the- 
nuts of several palms, especially those of 
the macuja. These nuts, which are so hard 
as to be difficult to break without a heavy 
hammer, are crushed to a pulp by the power- 
ful beak of this macaw. 
Crests among parrots are common enough,, 
but only one species wears a frill ; this is 
the Hawk-billed Parrot of the Amazon 
Valley. It is closely related to the large 
and well-known AMAZON PARROTS, and has 
been aptly described as a most extraordinary 
bird. Its coloration is striking — green above,, 
with a brown head; the frill or ruff around 
the neck shows up in strong contrast, being 
dark red, with blue edges, and barred with 
blue. The feathers of the breast and abdo- 
men, like the frill, are also red and blue, 
whilst the under-surfaces of the tail and 
wings are black. It is only when the bird is 
excited or angry that the ruff is raised.

BLACK COCKATOO 
Found in pairs in thick forests 
The Hanging-parrots are about the 
same size as the well-known “ love-birds,” 
and remarkable for their habit of sleeping 
suspended head-downwards by one foot from 
the boughs of trees. They are all brilliantly 
coloured birds, and have a fairly wide range, 
extending from India and the Philippines 
through the Malay region as far east as Duke 
of York Island. 
The Australian Budgerigars, or Grass- 
PARRAKEETS, need no description here; but 
it is interesting to note that nearly allied to 
them is a small species known as the SwAMP- 
or Long-tailed Ground-parrakeet. As its
