Cat Bird of the Colonists of New South Wales. 
So far as our knowledge extends, this fine species is only found in New South Wales, where it inhabits all 
those luxuriant forests that extend along the eastern coast between the mountain ranges and the sea; those 
of Illawarra, the Hunter, the MacLeay, and the Clarence and the cedar brushes of the Liverpool range 
being, among many others, localities in which it may always be found ; situations suitable to the Regent and 
Satin Birds are equally adapted to the habits of the Cat Bird, and I have not unfrequently seen them all 
three feediug together on the same tree, when the branches bore a thick crop of berries and fruits. The 
wild fig, and the native cherry, when in season, afford it an abundant supply. So rarely do they take insects, 
that I do not recollect ever finding any remains in the stomachs of those specimens I dissected. In its dis- 
position it is neither a shy nor a wary bird, little caution beg required to approach if, either when feeding 
or while quietly perched upon the lofty branches of the trees. It is at such times that its loud, harsh aud 
extraordinary note is heard: a note which differs so much from that of all other birds, that having been 
once beard it can never be mistaken. In comparing it to the nightly concerts of the domestic cat, I con- 
ceive that I am conveying to my readers a more perfect idea of the note of this spectes than could be given 
by pages of description. This concert, like that of the animal whose name it bears, is performed either by 
a pair or several individuals, and nothing more is required than for the hearer to shut his eyes from the 
neighbouring foliage to fancy himself surrounded by London grimalkins of house-top celebrity. 
While in the district in which this bird is found, my almost undivided attention was directed to the acqui- 
sition of all the information I could obtain respecting its habits, as I considered it very probable that it 
might construct a bower similar to that of the Satin Bird; but I could not satisfy myself that it does, nor 
could I discover its nest, or the situation in which it breeds; it is doubtless, however, among the branches 
of the trees of the forest in which it lives. It certainly is not a migratory bird, although it may range from 
one portion of the brushes to another, according as the supply of food may be more or less abundant. 
The sexes do not offer the slightest difference in plumage, or any external character by which the male 
may be distinguished from the female; she is, however, rather Jess brilliant in her markings, and somewhat 
smaller in size. 
Head and back of the neck olive-green, with a uarrow line of white down cach of the feathers of the 
latter; back, wings and tail grass-green, with a tinge of blue on the margins of the back-feathers ; the wing- 
coyerts and secondaries with a spot of white at the extremity of their outer web; primaries black, their 
external webs grass-green at the base and bluish green for the remainder of their length; all but the two 
central tail-feathers tipped with white s all the under surface yellowish green, with a spatulate mark of yel- 
lowish white down the centre of each feather; bill light horn-colour; irides brownish red ; feet whitish.
