SERICORNIS MACULATUS, WKm
Spotted Sericornis.
Sericomis maculatus, Gould in Proc. of Zool. Soc., January 27, 1847.
Goor-gal, Aborigines of the mountain districts of Western Australia.
T he present bird, to which I have assigned the specific term o f maculatus, has always been a source o f perplexity
to me, from the circumstance o f its varying considerably in its markings; after mature consideration,
however, I am induced to regard the specimens from South Australia, Western Australia and the north
coast as referable to one and the same species, each however possessing trivial differences by which it may
be known from whence it was received. Specimens from the Houtman’s Abrolhos are o f a rather smaller
size, of a much greyer tint on the back, and have much darker-coloured legs. I believe that the bright
yellow wash on the under surface of some individuals is characteristic of newly moulted or young birds: in
this species, not only is the throat spotted with black, but the spotting extends over the chest and some
distance down the flanks; it has at all times the tail tipped with white, a character which serves at once to
distinguish it from S. osculans and S. frontalis. Scrubby places, and ravines covered with dense herbage,
whether in sterile or humid situations, are its favourite resort. It has the same shy disposition and retiring
habits as the other members of the genus, depending for safety rather upon its creeping, mouse-like
habits than upon its powers o f flight, which are indeed seldom resorted to.
Its note is a harsh, grating kind of twitter, often repeated.
The nest is a warm, dome-shaped structure, formed of leaves and grasses, and lined with feathers; the
eggs are reddish white, minutely freckled and streaked with reddish brown, particularly at the larger end ;
they are three in number, nine lines long by seven lines broad.
All the upper surface, wings and tail brown; the latter crossed near the tip with a broad band of blackish
brown, and the outer feathers slightly tipped with white; forehead and lores deep black; stripe above
and a small patch below the eye white; spurious wing-feathers black, margined on their inner web with
white ; under surface in some specimens greyish white, in others washed with yellow; the feathers of the
throat and chest spotted with black on a light ground ; irides greenish white.
The female is somewhat smaller than her mate, and has the lores brown instead o f black; in other
respects her plumage is very similar to that of the male.
The upper figure in the accompanying Plate represents a female, and the lower probably a young male;
the figures are of the natural size, from specimens killed in Southern and Western Australia.
