"The White Cockatoo was common everywhere, and was 

 generally seen in pairs. It utters the most discordant shrieks 

 and noises on observing an intruder, and is most annoying 

 when one is in pursuit of other birds. On two or three 

 occasions I have seen pairs entering or leaving what I took 

 to be their nesting-holes , these were usually situated in the 

 straight clean trunk of a very tall tree, and at a great height 

 from the ground." — C. H. B. G,
