SERICORNIS CITREOGULARIS , Gould.
Yellow-throated Sericornis.
Scrimrnis ntnogularis, Gould in Proc. of Zool. Soc., Part V. p. 133 ; and in Synopsis of the Birds of Australia,
Part IV.
T his is the largest and most attractive species of the genus yet discovered, and so. far as I am aware, its
habitat is restricted to the south-eastern portions o f Australia, where it dwells exclusively in the districts
known by the name o f “ brushes.” I personally observed it in those of Hlawarra, and o f the Hunter, and in
the cedar brushes o f the Liverpool range. It frequents the most retired parts of the forest, living in gullies
and under the canopy o f lofty trees, hopping about among the stems of the tree-fern, fallen trunks of
patriarchal gums and moss-covered stones. It rarely flies, and when disturbed, seeks seclusion and safety
by hopping away among the underwood. Its food, which consists of insects.of various kinds, is obtained
on the ground or among the trunks of the prostrate trees, over which and the large stones it passes
with much ease and agility.
'The sexes are very similar in colour, but the female may at all times be distinguished by her smaller
size and the less strongly contrasted tints of her plumage, particularly in the hue o f the streak running
through the eye and extending over the ear-coverts, which is neither so dark nor so broad as in the male.
One o f the most interesting points connected with the history of this species is the situations chosen for
its nest. All those who have rambled in the Australian forests must have observed, that in their more
dense and humid parts an atmosphere peculiarly adapted for the rapid and abundant growth o f mosses of
various kinds is generated, and that these mosses not only grow upon the trunks o f decayed trees, but are
often accumulated in large masses at the extremities of the drooping branches; these masses often
become of sufficient size to admit of the bird constructing a nest in the centre o f them with so much art
that it is impossible to distinguish it from any o f the other pendulous masses in the vicinity. These
bunches are frequently a yard in length, and in some instances hang so near the ground as to strike the
head of the explorer during his rambles ; in others they are placed high up upon the trees, but only in such
parts of the forest where there is an open space entirely shaded by overhanging foliage: as will be readily
conceived, in whatever situations they are met with, they at all times form a remarkable and conspicuous
feature .in the landscape. Although the nest is constantly disturbed by the wind and liable to be shaken
when the tree is disturbed, so secure does the inmate consider itself from danger or intrusion of any kind,
that I have frequently captured the female while sitting on her eggs, a feat that may always be accomplished
by carefully placing the hand over the entrance; that is, if it can be detected, to effect which no slight
degree of close prying and examination is necessary.
The nest is formed of the inner bark of trees, intermingled with green moss* which soon vegetates;
sometimes dried grasses and fibrous roots form part of the materials of which it is composed, and it is
warmly lined with feathers. The eggs, jvhich are three in number and much elongated in form, vary
considerably in colour, the most constant tint being a clove-brown freckled over the larger end with dark
umber-brown, frequently assuming the form o f a complete band or zone.: their medium length is one inch,
and their breadth eight lines.
Lores circle around the eye, and the ear-coverts deep black; a conspicuous line o f yellowish white above
and for some distance beyond the e y e ; crown of the head, and all the upper surface, secondaries, wing-
coverts and tail reddish brown, becoming more rufous on the upper tail-coverts and tail; outer edges ol
the primaries olive; spurious wing blackish brown; throat yellow; chest and flanks olive-brown; centre
o f the abdomen white; bill brownish black; irides reddish brown; legs purplish flesh-colour, in some
specimens flesh-white.
The figures represent the two sexes of the natural size.
