my camp, and was forced to stop at an oak tree, my notice 

 being called to a female Bower-Bird which flushed out from 

 a cluster of mistletoe in the tree. On climbing, I found a 

 nest carefully concealed in the mistletoe, which contained 

 3 fresh eggs. The nest was constructed of similar material, 

 etc., to that of the Black- throated Butcher-Bird (Cracticus 

 robustics), only lined with leaves of the spotted Eucalyptus 

 instead of small twigs. 



" I carefully emptied the nest of its contents, but un- 

 fortunately the nest could not be removed, on account of 

 the sticks of the same being so intermingled with the twigs 

 of the mistletoe, the latter growing on a very thick limb. 

 After making further searches, I succeeded in finding nine 

 more nests, all of which were built in oak trees, and in same 

 position as the first nest found, with the exception that four 

 of them were built in the upright forks of the oaks, and not 

 in the mistletoe as the remaining six were. In the nine 

 nests found there were eggs in four of them, out of which I 

 got one fresh set of 2, and a few addled eggs, the balance of 

 the eggs being too far advanced in incubation to be blown. 

 The remaining five nests cell contained young birds covered 

 with down, and in one nest I found one young bird possessing 

 four legs, and I regret I did not keep the curiosity, instead 

 of placing it back into the nest. 



" In all, I only procured 7 eggs, which varied much in 

 size and colour. Out of the ten nests found, the following 

 is the detailed result : — 



1 nest contained set of 3 eggs (fresh). 



1 ,, ,, ,, 2 eggs (almost fresh). 



1 ,, ,, ,, 1 egg (addled) and 1 bird. 

 4 nests ,, ,, 3 young birds each. 



2 ,, ,, ,, 2 eggs each (heavily incubated). 



1 nest ,, ,, 3 eggs (1 addled, 2 heavily incubated). 



" The majority of the nests were 100 or 200 yards apart, 

 at an elevation of about 20 to 30 feet, and mostly placed 

 near the trunk of the tree, just where the smaller twigs 

 branch off near the topmost part. The birds were very tame, 

 and allowed their nests to be robbed without attempting to 

 attack the intruder.
