BIRDS OF TASMANIA. 117 



does great damage to the grain just when it sprouts, and also when 

 in the ear. It is not so much the amount of grain consumed as 

 the quantity destroyed that is objected to, for a small party of 

 birds will trample down a large patch in the course of a night, 

 and make it look as though an elephant had been rolling there.. 

 The places trampled down are often circular in shape, as though 

 they had been used as play-grounds. When a small flock or even 

 a pair of birds are feeding in or about a grain field, one bird is 

 always on the watch, and gives a short cry of alarm should danger 

 threaten. As a natural result of its mischievous traits, a relent- 

 less war with poison and gun is waged on this unfortunate fowl. 

 In several instances that have come under my notice the charges 

 brought by farmers have been fully sustained. When not engaged 

 in purloining forbidden grain, the food of this species consists 

 of a certain quantity of aquatic vegetation and a miscellaneous 

 assortment of insects gathered on land and out of the water, 

 admixed among all of w r hich is always more or less gravel, used 

 as an aid to digestion. Owing to the weakness of the muscles 

 of the chest and wings, the Native-Hen is almost, if not quite, 

 incapable of rising about the surface of the ground. On the other 

 hand, the leg and thigh muscles are well developed. As an article 

 of diet this bird is despised by all except Chinamen, who, I am 

 given to understand, use it for making certain dishes of which 

 they are very fond.
