NEED AND VALUE OF ATTRACTING BIRDS 11

 could find hardly an insect. Thus these nut- 

 hatches saved him thousands of dollars in one 

 winter. 



Such facts as these are worthy of the careful 

 consideration of every fruit-grower and farmer. 



Problems of Bird Life 

 The chief problems in the bird's life have to 

 do with the securing of food and water, the rear- 

 ing of the young, and protection at all times 

 from the dangers to which they are exposed. Ef- 

 fective means of attracting birds must take all 

 these problems into account. The food-require- 

 ment may be partly met by feeding birds in win- 

 ter and planting shrubs and trees which provide 

 fruit. The demand for water may be met by 

 providing fountains which may serve for bathing
