8 THE GEELONG NATURALIST. 
` I have had correspondents especially on the look-out for their: 
nests, and during my own excursion, Nov., 1891, to the “ Big: 
Scrub " of N. S. Wales, where I heard the delightful little songs of 
many Rose Robins, my companion and I both failed to find a. 
nest. 
However, last season, Mr W. Delaney, of the Omeo district of. 
Victoria, became acquainted with this desideratum, and has enriched: 
our oological knowledge by finding several nests. A nest, together 
with a specimen of the bird procured by him on Wombat Creek, 
has been kindly sent to me. 1 append Mr Delaney’s note :— 
“The Rose Robin arrives in the Glen Wills distriet end of 
September, andlaysduring Octoberand November. I found two nests 
with young in November (3 in each) the last two years. They. 
leave during April for the north. In the Jumbunna district, where: 
I lived for some years, the season is much the same. I suppose 
you are aware they catch their food on the wing, very much like 
the rantai] Fly-catchers, and are, therefore, an exception to other- 
obins.”

OBSERVATIONS.—The Cautious Hylacola or Chestnut-rumped 
Ground Wren, as far as we are at present aware, has only been found 
in the drier tracts of Victoria and South Australia. 
I believe the late Mr R. H. Nancarrow was the first to discover 
this rare nest. Writing to the Field Naturalists’ Club of Victoria, 
March, 1888, he stated :—‘‘A bout twenty years ago I used to do » 
good deal of nest-hunting in the Whipstick, an isolated tract. of,
