The Yellow, Palm, and Prairie Warblers are the three " Wood 

 Warblers " that are rarely found in the woods. The latter, however, 

 differs decidedly in habits from either of the former. It is a rather

During the nesting season Oven-birds are among our commonest 

 woodland birds. We hear them everywhere ; one singer scarcely ceases 

 before another begins. But when the song period has passed how
