GROUND WREN. 
seen on any species of those genera, and remembering the name c Red-rumped 
Hylacola,’ we concluded that this was one — the first and only time I have 
found a vernacular name of any use for identification purposes. . . . They 
ran with tail held up at right angles to the body at great speed, and dodged 
in and out of the fallen brushwood in most agile fashion. In perching they 
also held the tail high, after the manner of a Calamanthus. Nest a dome- 
shaped structure of grasses placed in a small hollow in the ground which 
the birds had scraped out at the foot of a tuft of herbage. It was lined 
warmly with feathers and had an entrance at the side.” 
Captain S. A. White states : “Is found in the scrub and mallee country 
in many parts of this State. A lively bird hopping about amongst the under- 
growth with tail almost over their backs, uttering a low chitting call. The 
form inhabiting Kangaroo Island is fairly plentiful.” 
Mr. A. G. Campbell has written : “Is plentiful upon Kangaroo Island 
in short scrub and heather. The young is distinguished by a light fawn-coloured 
throat and chest, though it has the dark centred feathers of the old bird ” ; 
while he added “ Hylacola pyrrhopygia is found about the heather country 
of the Grampians in Victoria but no further east. The male has a pleasing 
song which it utters after the manner of a Calamanthus from the twig of some 
bush.” 
Under the name H. pyrrhopygia Mr. F. E. Howe wrote: “Am not sure 
about this species but think I flushed one at Griffith’s Gully in very dense 
scrub,” and then under H. cauta sent me the following note : “ In the mallee 
when the day, is warm one would think it devoid of bird-life but when cool the 
sweet warbling song of this terrestrial and fleet-footed little creature was sure 
to be heard. They appear to be fond of locating themselves near a roadside 
or track and wherever the surveyors had cut tracks or traverses they appeared 
to congregate. They also like to place their nests under the fallen branches 
that had been cut down by the scrub cutters. On our last trip we found a 
fev nests on a traverse or cut line. One that was found by flushing the female 
contained three young fully fledged. They were identical in plumage to the 
parents, only the gape, which was of a creamy colour, disagreeing. Mouth 
orange and the irides dark brown. They flushed from the nest and it was a 
hard job to capture them as they fluttered and ran after the female through the 
scrub. On Oct. 10th Mr. J. Scarse piloted us to a thick patch of scrub in 
search of Leipoas ’ nests, and on descending a slight sandhill that was covered 
with a profusion of scrubby growths Mr. Ross flushed a bird from a nest that 
was placed under a thin dead bush ; it contained one youngster only that was 
blind and naked, the gape was creamish in colour and the skin all over the 
chick was very black.”
