Summary of the Preceding Five Tables. — The total number of 

 species given in the above lists of the species characteristic (mainly 

 exclusively so) of the North American Temperate Region is 135. Of 

 these 38 are restricted in the breeding season in their austral range to 

 the Cold-temperate District; about one third of them, chiefly natatorial 

 species, reach the Arctic coast ; 61 are similarly mainly limited to 

 the Middle-temperate District, but two or three reach the Arctic coast, 

 and nearly one third range into the Hudsonian Fauna ; 21 are limited 

 in their boreal range to the Warm-temperate District, the greater part 

 of which, even in the breeding season, range southward into the 

 tropics. Of the whole number, 90 are land birds, 23 being raptorial 

 species. Of the remaining 45 water birds, 7 are herons, 20 are Grallce, 

 and 18 are Natatores, 12 of the latter being Anatidce. 



In the li-t of those whose breeding habitat is the cold-temperate 

 portions of the continent (Table 1), 20 of the species are aquatic and
