As regards the occurrence of this finch what is said about the first Ploceidc- 
form applies to this one as well, namely that it was found sporadically, and conse- 
quently it was missing in some places. In the places where it was seen, it appeared 
very commonly in flocks. In Derby, where it was not found in Oct., I have seen 
it in the winter, and also in Meda and Beagle Bay.

Moulting. — It is rather strange that the crest of one bird is growing out at 
the end of April. One specimen, shot on the 18th of April, had signs of a crest 
(pins). Birds shot in Febr. at Sunday Island had this part bare. 
Ecological. — The big bower bird was rather common round Derby, at Meda 
and Sunday Island, and was also found in Beagle bay and Nooncanbah (Fitzroy river; 
WIDELL). 
At Derby, where in March and April it appeared in the village itself, I have 
found the play ground, built in the following way: 
In the bush, in a rather open piece of ground, overgrown with clusters of bushes, 
the bird had built its house between two bushes. The ground around it was hard, 
sandy and without any vegetation. The building materials were thin twigs, which 
had been fixed perpendicularly down in the ground in two rows, so that two thick, 
solid walls had been formed. The twigs in this »cottage» had been curved at the 
top in order to make a tunnel-shaped passage. Inside it was covered with shorter 
twigs, and in the middle there was a hole filled with rounded bones etc. At both
