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

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

 most persistent singer, keeping up his 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 

 his head 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 his search.
