 get to be abundant before leaving ; but from their habit of skulk- 

 ing among the rank weeds they are not so conspicuous as the 

 Blackbirds and other species which keep in flocks on the wing.

Towards the end of August they become abundant along the 

 marshy shores of Hamilton Bay, where they evidently find food 

 to suit their taste, and they continue to enjoy it till reminded by 

 the cool nights in September that it is time to be off to the south.
