The Eed-eye is our commonest Yireo, one or more pairs occurring 

 in every piece of woodland, except in tlie dry pine barrens. He is a 

 most persistent singer, keeping up liis deliberate warble throughout 

 the day. Wilson Flagg admirably describes the song as "You see it — 

 you know it— do you hear me — do you believe it?"' There is a pause 

 between each sentence as if the bird were conducting a sort of argu- 

 ment; a peculiarity that has earned him the name "Preacher-bird" 

 in some places. The actions of the Vireo are quite as deliberate as 

 his song ; he goes along the twigs in a matter-of-fact fashion, turning 

 ]iis liead first on one side then on the other, stopping to pick up a 

 bug or a caterpillar and then, wiping his bill on the limb, continues 

 on hi& search.
