BIRDS'-NESTS 



It had been used for many years, and he was told 

 that the eagles made it a sort of home or lodging- 

 place in all seasons. 



The eagle in all cases uses one nest, with more 

 or less repair, for several years. Many of our com- 

 mon birds do the same. The birds may be divided, 

 with respect to this and kindred points, into five 

 general classes. First, those that repair or appro- 

 priate the last year's nest, as the wren, swallow, 

 bluebird, great-crested flycatcher, owls, eagles, fish 

 hawk, and a few others. Secondly, those that build 

 anew each season, though frequently rearing more 

 than one brood in the same nest. Of these the 

 phoebe-bird is a well-known example. Thirdly, 

 those that build a new nest for each brood, which 

 includes by far the greatest number of species. 

 Fourthly, a limited number that make no nest of 

 their own, but appropriate the abandoned nests 

 of other birds. Finally, those who use no nest at 

 all, but deposit their eggs in the sand, which is the 

 case with a large number of aquatic fowls.
