willow-shrub zone, (3) the rush-flag- zone, and (4) the grass- 

 buttonbush zone. 



Not only are the plants of each of these areas different, 

 but also their animals and physical features. They vary as 

 to the amount of water present. This never is deep. In the 

 larg-est pond, near Charleston, it is seldom much more than 

 a foot. The bottom soil of the Charleston ponds is every- 

 where of hard, stiff, black clay. Since these four zones are 

 fairly distinct bird habitats, the birds of each will be consid- 

 ered separately. The data will be collected in annotated lists. 



BIRDS OF THE COTTON WOOD-WILLOW CENTER. 



Butorides virescens virescens — Green Heron. Noted on May 27, 

 1912, when a nest was found nine feet up in a cottonwood. It was 

 composed of sticks mostly about a foot in length and put together 

 in a loose manner, making the nest a flimsy structure. It contained 

 three eggs. 



Zenaidura macroura — Mourning Dove. Frequently seen in this 

 wooded area. 



Melanerpes erythrocephalus — Red-headed Woodpecker. Seen on 

 one occasion about the cottonwoods. 



Colaptes auratus hiteus — Northern Flicker. A nest found seven 

 feet up in a willow stub on May 21, 1914. 



Corvus hrachyrliynchos brachyrhynchos — Crow. One seen on a 

 nest about thirty feet up in a large cottonwood on April 15, 1915, 



Agekiius phoeniceus plioeniceus — Red-winged Blackbird. The 

 birds frequently alight in the trees, and in the early spring com- 

 panies of males, sometimes large with a hundred or more birds, 

 sing from the treetops. 



Sturnella magna magna — Meadowlark. - One noted singing from 

 the top of a cottonwood on April 15, 1914. 



Euphogus ca7-oJiniis — Rusty Blackbird. A small company of 

 them was singing from the cottonwoods on April 16, 1913. 



Quiscahis quiscnla aeneus — Bronzed Grackle. Frequently seen 

 in the trees. 



Planesticus )nigratorius migratorius — Robin. A large company 

 of robins seen about the cottonwoods on April 15, 1915. 



Sialia sialis sialis — Bluebird. A few noted about the trees, and 

 an old nest, in all probability that of the bluebird, was found in 

 a tree cavity.
