Macaws; yet some species are sober in tint, and that of the beak 
and feet varies considerably in different forms. Stringops has a 
dise of stiff feathers round the eye, Vymphicus and the Cacatuinae 
possess crests, Deroptyus broad erectile nape-plumes. Bare fore- 
heads, cheeks or orbits, of a red, pink, blue, yellow, black, grey, or 
white hue are found in Microglossus, Cacatua, Licmetis, Anodo- 
rhynchus, Cyanopsittacus, Ara, Poeocephalus, Psittacus, Coracopsis, 
and Dasyptilus ; while powder-down patches or tufts occur on the 
neck, shoulders, and sides of the Cacatuinae, Psittacus, and Chry- 
sotis. The length varies from some thirty inches in the Great 
Black Cockatoo (JZicroglossus) to about three in the diminutive 
Nasiterna pygmaea. The name Macaw is applied to Ara and 
its nearest allies, Love-bird to Agapornis and Psittacula, Parakeet 
to Platycercus and Palacornis, Lorikeet to Loriculus, Charmosyna, 
and Coriphilus, Lory to Eclectus, Trichoglossus, Lorius, Chalco- 
psittacus, and Hos, King Lory to Aprosmictus. 
Parrots usually feed and roost in company, though in Le/ectus 
the habits are said to be more solitary; the males are, however, 
monogamous, each courting a single female, which twitters and 
rolls the head from side to side when love-making. The haunts 
include wooded districts, grassy plains, or even rocky hills and 
sandy flats; Stringops being almost entirely terrestrial, JZelo- 
psittacus and Neophema (Grass-Parakeets), with Geopsittacus and 
Pezoporus (Ground-Parakeets), being mainly so, while Cockatoos 
and many other forms habitually frequent high trees, though 
Cacatua galerita, Licmetis nasica, and several species of Platy- 
cercus spend much time upon the ground. Most Parrots walk 
with considerable ease, and chmb well; their flight is commonly 
low and undulating, but is comparatively strong in Westor, the 
Macaws, the Lories, and the like; the last-named climb less, and 
often hop along the ground. Loriculus, when sleeping, generally 
hangs by one foot. Little drink seems necessary, as the vegetable 
food is ordinarily succulent; plantains, papaw-apples, figs, and 
tamarinds being varied by flowers, buds, leaves, hard palm-nuts, 
and fruits of Platanus, Casuarina, Banksia, Cactus, or Capsicum. 
Grass-Parakeets and their nearest allies subsist almost entirely 
on grass-seeds and grain, Licmetis and some other Cockatoos dig for 
tubers and bulbs, Calyptorhynchus and Nestor search the bark of 
trees for insects, while the latter and the Loriinae suck honey 
from the flowers of Phormiwm and Eucalyptus. Nestor notabilis,
