134 BIRDS OF TASMANIA. 



when the tide is just on the turn. As the waves retreat the birds 

 run down as far as they can and hunt about in the wet sand witii 

 great energy. As the waves come tumbling shorewards back the 

 birds scurry as fast as their legs will carry them, only to hurry 

 down the sandy beach again in the wake of the retreating breakers. 

 Unless hard pressed this bird does not take readily to flight, 

 preferring to trust to its legs to carry it out of danger.

Its appearance in certain localities depends greatly upon 

 chmatic conditions. During a wet season, when there is an 

 abundance of water in swamps and lagoons, it is sure to be found 

 in greater or lesser numbers. The White-headed Stilt is very 

 graceful in all its actions ; but for its delicate proportions its long 

 legs would appear incongruous. It associates in small flocks 

 along the maigins of inland swamps and lagoons, where its long 

 legs are of great use in allowing it to wade among the aquatic 

 plants and search for its food. 



The late Sir Walter Buller says of this species: — " Notwitli- 

 standing the extraordinary length of its legs, this bird is most 

 graceful in all its movements; it is a very prcttj' sight to watch a 

 flock of them on the edges of a lagoon stalking about in the
