Family MNIOTILTID^.— Wood Warblers. 



In the words of that pleasing writer, Dr. Elliott Coues,* " The war- 

 blers have we always with us, all in their own good time; they come 

 out of the south, pass on, return, aud are away again, their appearance 

 and withdrawal scarcely less than a mystery; many stay with us all 

 summer long, aud some brave the winters in our midst. Some of 

 these slight creatures, guided by unerring instinct, travel true to the 

 meridian in the hours of darkness, slipping past like a 'thief in the 

 night,' stopping at daybreak from their lofty flights to rest and recruit 

 for the next stage of the journey. Others pass more leisurely from 

 tree to tree, in a ceaseless tide of migration, gleaning as they go; the 

 hardier males, in full song and plumage, lead the way for the weaker 

 females and the yearlings. With tireless industry do the warblers be- 

 friend the human race; their unconscious zeal j)lays due part in the nice 

 adjustment of nature's forces, helping to bring about the balance of 

 vegetable and insect life without which agriculture would be in vaiu. 

 They visit the orchard when the apple and pear, the peach, plum, and 

 cherry are in bloom, seeming to revel carelessly amid the sweet-scented 

 and delicately-tinted blossoms, but never faltering in their good work.
