ge:oivOgy of IvA saivLE county. 



The Lotig'-billed Curlew — Numenius long-irostris 

 is no long-er found here. 



Family Ardeidae — Herons — The g-reat blue heron 

 — ^Ardea herodias is found along' the rivers. The snowy 

 eg-ret, little white eg-ret — Garzetta candidissima— is 

 sometimes seen along- our streams. 



The Bittern, Indian Hen, Stake Driver, Pump 

 Thunder— Botaurus lentig-inosus — is less common than 

 formerly, but its deep thunder-like notes are often 

 heard. The green heron — Butorides virescens— and 

 the least bittern— -Ardetta exilis — inhabit wet places. 



Family Gruid^ — Cranes, sandhill or brown crane 

 — Grus canadensis — ^once very common, now seldom 

 seen; sometimes heard as they pass over, gfoing- north 

 in the spring*. 



Family Rallidae— Rails are found about swamps. 



Family Anatidae — Ducks — the wild goose — Ber- 

 nicla canadensis — the brent — Bernicla bernicla— and 

 several species of ducks once made this region their 

 home, but have ceased to do so. 



The Pelican — Pelecanus trachyrhynchus — is occa- 

 sionally seen. 



The White-wing-ed Gull — Larus leucopterus— 

 visits our streams. 



The Great Northern Loon or Diver— Uranator 

 imnier — is sometimes seen in the spring along the Illi- 

 nois, and the swan— Cygnus buccinator — may be seen 

 occasionally. 



Other species will no doubt be found. The sub- 

 ject has not been carefully worked up, and much 

 remains to be done. Moreover, many birds are migrant 

 and some follow^ man, while storms, the gun and the 

 want of sound sense which characterizes man often 

 destroy a species in a given territory. Hence we find 

 changes constantl}^ in progress.
