The blue-winged teal is one of the commonest ducks throughout 

 the middle portion of North America, but towards the west coast it 

 becomes scarce, its place being filled by the more abundant cinna- 

 mon teal. It breeds through most of its United States and northern 

 range and migrates early, before the really cold weather. By prefer- 

 ence it inhabits the marshes and grass-fringed ponds, keeping out of 

 sight when it can ; but during migration, like many other ducks, 

 it depends for safety on a wide expanse of open water.
