 together. 



Sometimes a single bird amused itself for hours at a 

 time at one of the playhouses, carrying the shells through 

 the house from one side to the other. If two or more 

 birds were present at the same time they invariably chased 

 each other in a playful manner, and sometimes a squabble 

 arose among them, which seemed to be a kind of mock 

 fight. 



Sticks, coloured stones from the hills and river banks, 

 fruit stones, berries, a metal button, a small piece of tin, a 

 piece of native twine, and a number of wallaby teeth, were 

 among the numerous articles lying about these playhouses.
