Birds of Oregon and Washington 291 



life, doing this during the late autumn and in 

 the early winter, when bird-life invites less out- 

 of-door study. As the spring approaches, the 

 birds that in the first year's course were not 

 named, should be observed, and those already 

 identified should be given further notice. 



The following course is recommended : In the 

 early autumn months, "Where have our birds 

 gone ? " " Where are they going ? " " Some- 

 thing about migration." "In what Southern 

 lands do certain species of our birds pass the 

 winter ? " " What do they do there ? ' " Do 

 they nest ? " " Why do they migrate ? " " Is it 

 the winter that occasions their going and coming, 

 or is it food, or both ? " 



Watch this year for the arrival of the birds, 

 observing about what time the different species 

 come to their summer homes. 



In late January and in February, find further 

 what birds will nest about our homes, and pro- 

 vide the necessary conditions to have them make 

 their residence with us. Some birds need boxes 

 to build their nests in, while there are others 

 that will nest in our vines and shade-trees. See 

 again Chapter VII in this book.
