CLIMACTERIS ERYTHROPS, Gould. 
Red-eyebrowed Tree-Creeper. 
Climacteris erythrops, Gould in Proc. of Zool. Soc., Part YIII. p. 148. 
I obtained this new and highly interesting species while encamped on the low grassy hills under the Liver- 
pool range ; from the manner of its ascending the trees and keeping almost entirely to the small upright 
stems of the Casuarince, I believed it to be the White-throated Tree-Creeper ( Climacteris picumnus ) ; but 
having made it a rule to shoot an example of every species I observed in each newly-visited locality, I was 
in this instance rewarded with the acquisition of a new bird, which I afterwards found was numerous in 
this part of the country. But whether it is generally distributed over the colony, or merely confined 
to such districts as have a similar character to those in which I found it, I had no opportunity of as- 
certaining. So far as I could observe, its habits and manners bore a striking resemblance to those of 
the Climacteris picumnus. 
One singular feature connected with this species, is the circumstance of the female alone being adorned 
with the beautiful radiated rufous markings on the throat, the male having this part quite plain ; this I 
ascertained beyond a doubt by the dissection of numerous specimens of both sexes ; it is true that a faint 
trace of this character is observable both in Climacteris scandens and C. rufa, but the present is the only 
species of the genus in which this reversion of a general law of nature is so strikingly apparent. 
The male has the crown of the head blackish brown, each feather margined with greyish brown ; lores 
and a circle surrounding the eye reddish chestnut ; back brown ; sides of the neck, lower part of the back, 
and upper tail-coverts grey ; primaries blackish brown at tbe base and light brown at the tip, all but the 
first crossed in the centre by a broad band of buff, to which succeeds another broad band of blackish brown ; 
two centre tail-feathers grey, the remainder blackish brown, largely tipped with light grey ; chin dull white, 
passing into greyish brown on tbe chest ; the remainder of the under surface greyish brown, each feather 
having a hroad stripe of dull white, bounded on either side with black running down the centre, the lines 
becoming blended, indistinct, and tinged with buff on the centre of the abdomen ; under tail-coverts buffy 
white, crossed by irregular bars of black ; irides brown ; bill and feet black. 
The female differs in having the chestnut marking round the eye much richer, and in having, in place of 
the greyish brown on the breast, a series of feathers of a rusty red colour, with a broad stripe of dull white 
down their middles, the stripes appearing to radiate from a common centre : in all other particulars her 
plumage resembles that of the male. 
The figures are those of a male and a female of the natural size.
