Be-wo-wen, Aborigines of the lowland and mountain districts of Western Australia.
Wood Swallow of the colonists of ditto.
T h i s bird exceeds in size all other o f the Australian Wood Swallows, and as far as I am aware (not having
seen the species from Madagascar, figured in the “ Planches Enluminées,”) is the largest of the genus. Its
large tail, most of the feathers of which are broadly tipped with white, as well as the colouring of its plumage,
at once point out its close affinity to the Artamus sordidus and Artamus minor. Like them it possesses a very
extensive range of habitat, Mr. Robert Brown having found it at Broad Sound on the east, and Mr. Gilbert
on the west coast ; it is also a native of Timor.
In Western Australia, although a very local, it is by no means an uncommon species, particularly at Swan
River, where it inhabits the limestone hills near the coast, and the “ Clear Hills” o f the interior, assembling
in small families, and feeding upon the seeds o f the Xanthorrhoea, which proves that insects do not form the
sole diet o f this species ; with such avidity in fact does it devour the ripe seeds o f this grass-tree, that
several birds may frequently be seen crowded together on the perpendicular seed-stalks o f this plant busily
engaged in extracting them ; at other times, particularly among the limestone hills, where there are but
few trees, it descends to the broken rocky ground in search of insects and their larvae.
It breeds in October and November, making a round compact nest, in some instances of fibrous roots
lined with fine hair-like grasses, in^others o f the stems of grasses and small plants ; it is built either in a
scrubby bush or among the grass-like leaves of the Xanthorrhoea, and is deeper and more cup-shaped than
those o f the other members of the group. The eggs are subject to considerable variation in colour and in
the character o f their markings ; they are usually bluish-white, spotted and blotched with lively reddish
brown, intermingled with obscure spots and dashes of purplish grey ; all the markings being most numerous
towards the larger end ; they are about eleven lines long by eight lines broad.
The sexes are alike in colour, and can only be distinguished from each other with certainty by dissection.
I have remarked that specimens from Timor rather exceed in size those collected on the Australian
continent, and are somewhat lighter in Colour ; but these variations are too slight to be regarded as specific.
Crown o f the head, neck, throat and chest grey, passing into sooty grey on the abdomen ; space between
the bill and the eye, the fore-part o f the cheek, the chin, the upper and under tail-coverts jet-black ; two
middle tail-feathers black ; the remainder black, largely tipped with white, with the exception of the outer
feather on each side, in which the black colouring extënds on the outer web nearly to the tip ; wings deep
grey ; primaries bluish grey ; under surface of the shoulder white, passing into grey on the under side of
the primaries ; irides dark blackish brown ; bill light greyish blue at the base, black at the tip ; legs and
feet greenish grey.
The figures are thqse of a male and a female of the natural size.
