18 terrestrial ; of those breeding throughout the greater part of the 

 continent, 10 only are aquatic and 51 are terrestrial ; of those breeding 

 in the warm-temperate portions of the continent, 9 are aquatic and 9 

 terrestrial; of the 10 wide-ranging species, whose breeding habitats 

 embrace not only nearly the whole of temperate North America, but 

 extend also into the tropics, 1 only is a land bird, 3 being Herodiones, 

 4 Grallce, and 2 Natatores. Of the 9 species given in the Fifth Table, 

 which range in the breeding season throughout both the North American 

 and South American continents, none are aquatic ; 4 are owls, 3 hawks, 

 and 2 vultures. The most numerously represented family, and one of 

 those almost exclusively characteristic of the North American Temper- 

 ate Region (the Sylvicolidce), has but three species which range across the 

 continent, and only one of these is a typical representative of the family.
