BIRDS —NESTS 125 
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.
