PSEPHOTUS HASMATONOTUS, Gow. 
Red-backed Parrakeet. 
Platycercus hematonotus, Gould in Proce. of Zool, Soc., Part V. p. 151: and in Syn. Birds of Australia, Part IV. 
Tuts species inhabits the interior of the south-eastern division of the Australian continent; it is abundantly 
dispersed over the Liverpool Plains, and all the open country to the northward as far as it has yet been 
explored ; it also inhabits similar tracts of country in South Australia; on the plains around Adelaide it is 
seldom seen, but as the traveller advances towards the interior every succeeding mile brings him in contact 
with it in greater numbers. It is more frequently seen on the ground than among the trees ; and it evidently 
gives a decided preference to open grassy valleys and the naked crowns of hills, than to the wide and almost 
boundless plain. During winter it associates in flocks, varying from twenty to a hundred in number, which 
trip nimbly over the ground in search of the seeds of grasses and other plants, with which the crops of many 
that were shot were found to be distended. In the early morning, and not unfrequently in other parts of 
the day, I have often seen handreds perched together on some leafless limb of a Exealyptus, sitting in close 
order along the whole length of the branch, uutil hunger prompted them to descend to the feeding-ground, 
or the approach of a hawk or other enemy caused them to disperse. Their movements on the ground are 
characterized by much grace and activity, and although assembled in one great mass running over the 
eround like Plovers, they are generally mated in pairs,—a fact easily ascertained by the difference in the 
colouriug of the sexes; the rich red mark on the rump of the male appearing, as the bright sun shines upon 
it, ike a spot of fire. 
In the manner of its flocking and the situations it frequents, this bird is directly intermediate between 
the members of the genera Luphema and Platycereus ; the same remark holds good also with respect to its 
form and structures this fact, however, | have pointed out in the observations on the genus, and it is 
therefore unnecessary to repeat the details here. 
This bird has a pleasing whistling note, almost approaching to a song, which is poured forth both while 
perching on the branches of the trees and while flying over the plains. On the approach of the breeding- 
season it retires into the forest aud separates into pairs; the eggs, which are white and five or six in 
uumber, eleven lines long by eight and a half lines broad, are deposited without any nest in the spouts and 
hollows of the gum-trees. 
Crown of the head, back of the neck, cheeks and chest emerald-green, which is lightest on the forehead 
and cheeks ; back brownish green; rump scarlet ; tip and under surface of the shoulder, spurious wing, 
and the outer edge of the basal half of the primaries rich ultramarime blue; the blue of the shoulder above 
passing into sulphur-yellow, and forming a conspicuous spot of the latter colour in the centre of the 
shoulder; greater and lesser wing-coyerts and secondaries bluish green; upper tail-coverts and two centre 
tail-feathers green, passing into blue towards the tip, which is blackish brown ; the remainder of the tail- 
feathers green at the base, gradually passing into delicate greyish white on the imer webs and the tips ; 
centre of the abdomen yellow ; thighs dull bluish green ; under tail-coverts greyish white ; bill horn-colour ; 
feet brown; trides pale brown, 
The young male of the year differs from the adult im having those parts delicate greemsh grey which in 
tle latter are emerald-green ; in being destitute of the red colourmg of the rump, and of the yellow on the 
centre of the abdomen : and in having the bases of the secondaries and some of the primaries white. 
The Plate represents a male and female of the natural size.
