47. Acgialitis semipcilmata. Semipalmated Plover. A single 
bird observed at Sheldon, August 7, 1913, is the only record for 
the two counties. It was probably a regular migrant as I have 
found it quite common both north and south of here. 
48. *Oolinus virginianus virginianus. Bob-white. The Bob- 
white was locally a common breeding- species. Where hunting 
was forbidden they frequently nested about buildings and became 
quite tame. 
49. * Tympanuchus american us americanus. Prairie Chicken. 
This bird was only a tolerably common breeding species although 
considerable flocks often appeared during the winter. The last 
nest record I have is June 10, 1909. This nest contained twelve 
eggs and was built in the weeds and grass along a fence. 
50. * Z enaicliira mmroura carciinensis. Mourning Dove. This 
common breeding species was found nesting in artificial groves 
and feeding about barnyards. 
51. * C ircus kudsomps. Marsh Hawk. This was the only 
common hawk of the region. It nested in marshy hay lands. 
The three- or four nests I found usually had a little corn about 
each. This grain probably came from the cheek pouches of the 
striped gopher {Spermophilus tridecemlineatus} and gray squir- 
lels (8. franklini) brought to the nestlings though some of the 
farmers accused the hawk of eating corn. 
52. Accipiter covperi. Cooper Hawk. A young bird barely 
able to fly, was found in the city park at Sheldon, August 6, 
1913, and it is the only definite record that I have. It probably 
nested in the heavier timber along the Little Sioux. 
. 53. Buteo borealis Jtrideri. Red-tailed Hawk. Red tails 
were common in migration, and possibly nested in the heavy 
timber: H. C. Oberholser says that breeding birds of this re- 
gion as well as most migrants are of this subspecies. 
54. Haliaeetus leucocephaius leucocephaius. Bald Eagle. .1 
have examined two specimens taken in the county and there are 
probably others in existence, as one of these birds is shot every 
few years. 
55. Falco' sparverius sparverius. Sparrow Hawk. This little 
hawk was common in the fall. At this season it was usually 
found perched on the telephone and telegraph poles on the look- 
out for grasshoppers, locusts and other insects.
