342 KEY TO WARBLEBS 



Green, Blue, and Prairie. The Maryland says 

 witch-i-ty, witch-it-ty^ witcli-it-ty ; the Kentucky, 

 hlur-wee^ Mur-toee^ klur-wee^ or tur-dle f/ee, tur-dle 

 dee ; the Oven-bird calls teach-er or teach ; and 

 the Water-Thrushes and Chat have famous songs. 

 As the Warblers live exclusively on insects, 

 they go far south in winter — many of them to 

 South America — so that, small as they are, they 

 perform remarkably long journeys, many nesting 

 far to the north and wintering in the tropics. 

 When seen on their migrations they are hurrying 

 through, and present a very different apj^earance 

 from the quiet Sparrows who have weed seeds 

 enough to depend on if they are overtaken by a 

 cold wave.
