THE BIRDS OF AUSTRALIA. 
lovers, and also as an aid to future collectors in securing their eggs. Shortly 
after my arrival at Lockerbie, and while watching a pair of Manucodes, I noticed 
a pair of Butcher-Birds {Cracticus quoyi) [rufescens) building their stick nest 
in a small tree, and soon afterwards located the unfinished nest of the Manucodes 
in a tree about 30 yards from that of Cracticus quoyi. The Manucodes finished 
building first, and I secured a pair of eggs from their nest. One egg was laid 
in the Butcher-Bird’s nest, and some mid creature took it, and the birds left 
the locality. Sometime afterwards I located another nest of Cracticus quoyi, 
containing one egg, and here also was a pair of Manucodes. After watching 
them for some time I found that they were building in a small tree, about 
50 yards distant from the tree in which the Butcher-Bird’s nest was built. 
Both nests were about 50 yards from the scrub, in forest country. Five days 
later I returned and secured the eggs of the Butcher-Bird, the Manucode’s 
nest being almost completed at the time. The same day, about half a mil e 
away, I found another nest of C. quoyi, containing four eggs, which I took. 
On descending the tree I noticed a pair of Manucodes a short distance 
away, and, as they seemed irneasy, I decided to watch them. After about 
an hour had passed, one of the birds fiew into the top of a tall tree, between 
30 and 40 yards distant from the tree from which I had recently taken the eggs 
of C. quoyi, and, on investigation, I found an almost completed nest. 
I returned to camp well satisfied, and about a week later visited the nests, 
only to find to my intense disgust that both were deserted, and that there were 
no signs of the birds about. Even then I did not grasp the idea that the birds 
had forsaken their nests because the Butcher-Birds had left the locality. In 
a week’s time I found another nest of C. quoyi, containing eggs, and a 
Manucode’s nest building in a tree about 50 yards away. I took the eggs of 
the former species, and returned in seven days to find that history had repeated 
itself, the birds were gone. Then I realized that the Manucodes built near 
C. quoyi for protection, and that if C. quoyi were disturbed, they left too. I 
now determined to hunt up all the nests of C. quoyi that I could, but, though 
I located several, I did not find the Manucodes also. Finally I found a pair 
of Butcher-Birds, and with them a pair of Manucodes. For several days I 
watched the birds without result, then gave up, but returned after ten days. 
The Butcher-Birds w^ere quiet, but the Manucodes were verj' restless when 
they saw me. As it was forest country, and near the edge of the scrub, I 
retired some distance and hid. After waiting some time, a White Cockatoo 
{Cacatua galerita) came slowly along and perched on the top of a bushy tree 
about 50 yards from the scrub. Instantly both the Butcher-Birds arrived, and 
a lively time ensued, which ended in all three birds landing on the ground at 
the foot of a tree. After putting up a good fight for a while, the Cockatoo
