Tuts is a very abundant species on the northern and north-western coast of Australia, inhabiting grassy 
meadow-like land and the edges of swamps, mostly feeding on the ground upon the seeds of grasses and other 
plants, sometimes single or in pairs, but more frequently in families of from ten to twenty in number. It 
frequently utters a rapid succession of double notes resembling ‘ ¢rin-se trin-se. Its flight is low, somewhat 
rapid and zigzag, seldom farther prolonged than from tree to tree. Specimens of this bird given me by iny 
friends Captain Grey and Mr. Bynoe from the north-west coast differ somewhat in plumage from those killed 
on the Cobourg Peninsula, the concentric bands on the breast are much finer, the extreme margins only 
of the feathers being black ; I haye one specimen also with the whole of the crown of the head of a deep 
blood-red, and others with more or less of this colour. _ That this kind of plumage is unusual is proved by 
the fact of numerous specimens from Port Essington not exhibiting it, and had I not seen others from the 
north-west with black crowns (with the exception of the band across the forehead), I should have regarded 
as specific what I now look upon as a mere local variety, or possibly a very old bird. 
This beautiful species has been named after Dr. Robert Brown, as a just tribute of respect for the high 
reputation he has attained as a scientific botanist. 
Crown of the head, lores and ear-coverts deep black ; cheeks snow-white, bounded below with blue ; 
breast and rump pale yellow, each feather slightly fringed with black ; feathers of the back deep black, with 
a broad margin of pale yellow; wing-coverts, outer webs of the secondaries and base of the primaries rich 
blue, inner webs of the primaries and secondaries deep black ; under tail-coverts scarlet ; centre tail-feathers 
green at the base, passing into blue on the margins and at the tip; lateral feathers deep blue at the base of 
the outer webs, brown at the base of the inner webs, and then pale blue terminating in white, with black 
shafts ; irides blackish brown ; bill light horn-colour, passing into blue at the base ; legs and feet blackish 
brown. 
Young birds are similar in colour, but have all the markings dull and indistinct; as the individual 
approaches to maturity the breast becomes ornamented with a number of crescent-shaped markings of black 
and pale yellow, and as the bird advances in age the yellow increases in extent and the black nearly 
disappears. ; 
The three figures in the Plate represent two males and a female ; the crimson-headed bird dravn from a 
specimen collected on the north-west coast, and the other male from one procured at Port Essington ; they 
are all of the natural size,
