OBSERVATIONS ON THE DISAPPEARANCE 
AND PROBABLE CAUSE, OF MANY OF OUR 
NATIVE BIRDS IN CENTRAL QUEENSLAND. 
(By H. Greensill Barnard) 
Tn making Central Queensland the portion of Aus- 
tralia on which my notes are based, is because I have 
spent many years there, and know the great changes which

greater changes have taken place in other parts, but those 
which caused many birds to disappear from Central 
Queensland will apply to those other parts.
