and the bastard-wing, together with the primary wing-coverts and the outer webs

another by the markings of the head and face, while a few differ by their smaller 
size. They are all essentially forest-dwelling birds, associating in flocks, and 
feeding upon the fruits of palms and other trees. They usually la} r from three 
to four eggs, and produce but one brood in the year. If taken sufficiently early, 
the young are extraordinarily tame ; and as these birds are very hardy, they are 
favourites in captivity, more especially as many of them rival the grey parrot in 
talking and mimicry. Indeed, the festive amazon frequently becomes sufficiently 
domesticated to be allowed to wander in gardens at large. 
HAWK-BIRRED PARROT (} liat. size). 
Hawk-Billed One of the most remarkable members of this subfamily is the 
Parrot. hawk-billed parrot (Deroptyus accipitrinus) of Guiana, the Amazon 
Valley, and North-East Brazil, which is the sole representative of its genus. It 
differs from the amazons by the presence of a tufted oil-gland, and by the 
relatively longer tail, and is specially characterised by the beak being rather 
short, and deeper than long, but above all by the elongation and breadth of the 
feathers on the hinder part of the neck, which form an erectile collar or ruff. 
The coloration of this extraordinary bird is very striking. While the back and 
upper surface of the wings are green, the head is brown, with hoary streaks on 
the sides; the elongated feathers of the nape, together with those on the abdomen
