repulsive as their food is to our noses and their feeding-habits to 

 our ideas. 



In conclusion, I would like to thank 'The Auk' for so courteously 

 extending its pages to me; I hope that these notes and suggestions 

 may do something of what I intended they should do — I hope 

 that they will show that bird-watching is the foundation of a real 

 science, the science of the behavior of birds in their natural en- 

 vironment. Bird-watching, too, is in itself a sport, as all who have 

 tried it well know; but those who attempt to understand the 

 motives of the birds, the connection of their doings and the origin 

 of their various habits, will find themselves not only experiencing 

 the sportsman's thrill, but also the intellectual interest of the de- 

 tective piecing together the broken chain of evidence, and the 

 human feelings of a spectator at the play.
