74 BIRDS OF TASMANIA. 



on the wing. In some localities the Wood- Swallow haa a bad 

 reputation as a destroyer of bees. Doubtless some are destroyed, 

 but I am of opinion more false bees or "drone-flies" are 

 destroyed than honey-bees. The movements of this bird when on 

 the wing are graceful in the extreme. Its broad pinions are 

 eminently suited for sailing over and among the trees of its haunts. 

 Occasionally it ascends to a great height, until it becomes a tiny 

 speck in the sky. Even when almost out of sight in the air, its 

 not unpleasant reedy notes can be distinctly heard. When at rest 

 it has the curious habit of every now and then flicking its tail 

 with a quick movement from side to side.
