ARTAMUS SUPERCILIOSUS, Gow. 
White Eye-browed Wood Swallow. 
Ocyplerus superciliosus, Gould in Proe. of Zool. Soc., Part 1V. 1836, p. 142; and in Syn. Birds of Australia, 
Part I. fig. 2. 
Tuere is no species of Artamus yet discovered to which the present yields the palm, cither for elegance 
of form or for the beauty and variety of its plumage; the only known species with which it could be con- 
founded is the -drtamus rufiventer, an Indian bird with the breast similarly marked, but which is entirely 
destitute of the superciliary stripe of white, which has suggested the specific name; in this character and in 
the rich chestnut colouring of the breast, it differs from every member of its tribe inhabiting Australia. Iam 
unable to say what is the extent of its range, but I am induced to believe that it is confined to Australia, and 
that in all probability it seldom leaves the interior of the country; the extreme limits of the colony of 
New South Wales, particularly those which border the extensive plains, being the only parts where it has 
yet been observed. I first met with it at Yarrundi on the Dartbrook, a tributary of the Hunter, where it 
was thinly dispersed among the trees growing on the stony ridges bordering the flats, 
From this locality to as far as I penetrated northwards on the Namol, as well as in the direction of the 
River Peel, it was distributed in similar numbers, intermingled with the Artamus sordidus, at about the ratio 
of one hundred pairs to the square mile, the two species appearing to live and pertorm the task of incuba- 
tion in perfect harmony, both being frequently observed on the same tree. In their dispositions, however, 
and in many of their actions they are somewhat dissimilar; the bird forming the subject of the present Plate 
being much more shy and difficult of approach than the Nass sordidus, which is at all times very tame ; 
it also gives a preference to the topmost branches of the highest trees, from which it sallies forth for the 
capture of msects, and to which it again returns, in the usual manner of the tribe. In every part where | 
have observed it, it is strictly migratory, arriving in summer, and departing northwards after the breeding- 
season, 
The nest is ever most difficult of detection, being generally placed either in a fork of the branches or in a 
niche near the bole of the tree, whence the bark had been partially stripped. It is a round, very shallow and 
frail structure, composed of small twigs and lined with fibrous roots; those I discovered contained two eves, 
but I had not sufficient opportunities for ascertaining if this number was constant. Their ground-colour is 
dull buffy white, spotted with umber-brown, forming a zone near the larger end; in some these spots are 
sparingly sprinkled over the whole surface; they have also the obscure grey spotting like those of 4, sordidus + 
the eggs are rather more than eleven lines long by eight and a half lines broad. 
The male has the lores, space surrounding the eye, and the ear-coverts deep black ; chin greyish black 
passing into blackish grey on the chest; crown of the head greyish black ; over each eye a pure white 
stripe commencing in a poimt, and gradually becoming wider or spatulate in form as it proceeds towards 
the occiput; all the upper surface, wings and tail fuliginous grey, which is lightest on the rump and tail ; 
all the tail-feathers tipped with white, except the outer web of the lateral feather, which is grey; under 
surface of the wimg pure white; all the under surface rich deep chestnut ; irides nearly black 5 bill light 
blue at the base, black at the tip; feet dark lead-colour. 
The female has a similar distribution of colouring, but differs from her mate in the following particulars - 
lores and a ring surrounding the eye jet-black; only an indication of the superciliary stripe ; throat erey ; 
tail not so distinctly tipped with white ; under surface light chestnut-red. 
The figures are those of a male anil a female of the natural size.
