lowest descent was 1,500 feet, between the summit of Barnard's Spur 
and the Whelanian Pools. IJsually it is found from 4,000 feet to 
5,000 feet. The note of the female— a bird of common gray plumage — 
is that of the ordinary green cat bird, in a sharper and shriller key. 
The male appears to possess the marvellous imitative powers of the 
Australian lyre bird. First you hear him croaking like a tree frog, 
and this note is followed by a low, soft, musical, pathetic whistle, 
succeeded in a rapid succession by an astonishing imitation of ap- 
parently all the birds in the scrub. The bower varies in size and 
shapp, hat in all cases differs from that of the other Australian bower 
birds Both Broadbent and myself have seen bowers up to a height 
of 8 feet. As a rule they are made between two small trees about 
4 feet or 5 feet apart. Short dead sticks and twigs are piled up 
against each tree in a gently contracting pyramid, and across from 
base to base extends an arch- shaped causeway, occasionally spanned 
by a connecting vine decorated with green mosses and tufts of tiny 
ferns. In and out and over and under and around this erratic struc- 
ture both male and female birds disport themselves in frequent 
playful festivities, like the lyre bird, regent bird, and satin and other 
bower birds remarkable for similar customs and proclivities. So far 
only one nest has been discovered — the one found by me on the 
summit of the Little Mulgrave Eauge. It was a round cup- shaped 
nest, decorated outwardly with the mosses and ferns used in ornament- 
ing the bowers. It contained only one egg, quite fresh ; so we have 
yet to learn if the bird lays one or more. Another specially interest- 
ing bird is Orthonyx spaldingi, or " Spalding's Orthonyx," named 
after Spalding, of the museum, one of the best taxidermists in 
Australia. This bird is peculiar to the district, and on Wooroonooran 
we found it from the base to the summit at 5,240 feet. It runs about 
on the ground in dense scrub and scratches among the leaves like the 
Coachwhip Bird {PsopTiodes crepitans), to which it bears a certain 
resemblance, though double the size and weight. Remarkable in this 
bird is the abnormal thickness and strength of the thighs. It has 
great imitative powers and a rich full gurgling voice of great compass, 
and apparently inexhaustible capacity. It is the noisest bird in the 
scrubs. The blacks call it " Chowchilla," probably " jowa-chilla," 
from "jowa" the mouth and "chilla" to gabble. The Pied Crow Shrike 
{Sfrepera graculind) they call " jowajowa," literally " all mouth," from 
the stonewalling proclivities of this noisy bird. The lovely Blue Wren 
(Maluris amabilis) we found at 2,000 feet, and the handsome fawn- 
coloured Nankeen Heron {Nycticorax caledonicus) was shot near the 
Palm Camp at 4,00u feet. On my first ascent of the mountain, in 
February, there were considerable numbers of the White-headed and 
Pheasant^ tailed Pigeons {CarpopTiaga norfolciensis and Macropygia 
pTiasianella) from 4,000 feet to 5,000 feet. These birds were breeding, 
and had their nests in the top of tree-ferns, 6 feet or 8 feet above the 
ground. Each nest contained a single egg or solitary young pigeon ; 
poor, soft, woolly little mites, crouching in helpless innocence in the 
open nests, dependent solely on their parents for protection against 
storms and rain. Both species were in grand condition, having a rare 
fattening ground among the berry-bearing trees of the summer months. 
The Common Jackass {Dacelo gigas) was seen up to 2,700 feet. JSTests 
of the Scrub Turkey were seen at 4,500 feet, but the Scrub Hen 
{Megapodius tumulus), one of the mound builders, was not heard or seen
