BIRDS OF MARSHALL COUNTY 135 



raut definite records. In addition to these the range of a num- 

 ber of species indicates that they should be found here, but the 

 writer failed to discover them. Some of those which sooner or 

 later are almost certain to be found are the loon (Gavia immer) , 

 Hutchin's goose (Branta cwnadensis hiitchinsi) , Virginia rail 

 (Fallus virginianus), Henslows sparrow ( Passe rherhulus liens- 

 lowi lienslowi), and several species of longspurs (Calcarius spp.). 



1. Podilymhus podiceps. Pied-billed Grebe. A tolerably 

 common migrant from March 26 to May 22 and from August 22 

 to November 4. 



A large flight of these gi'ebes alighted on Iowa river on April 

 24, 1914. Over 100 were counted in a tramp of about three 

 miles along the river. They continued unusually abundant until 

 ]\ray 4, when ten birds were seen. In fall they were not as 

 abundant as in spring, single birds being the rule. One bird 

 remained on the pond in the cemetery from October 7 to Novem- 

 ber 4. 



One was caught alive on the morning of April 24, 1914. It 

 was on the ground in a large pasture and seemingly unable to 

 rise. A specimen was collected August 27, 1913, on the Goose 

 ponds. 



2. Lams argentatus. Herring Gull. A rather rare migrant. 

 On iVfarch 25, 1913, a flock of seven large gulls over the pond 

 were rather doubtfully referred to this species. However, they 

 were a considerable distance away and the identification was not 

 absolutely certain. One was positively identified on March 30 

 of the same year and March 30, 1914, the wi'iter secured a speci- 

 men in immature plumage at the Goose ponds. The writer has 

 three other spring records, April 4, 1913, April 4, 1914, and 

 ]\Iarch 20, 1915, and one fall record October 16, 1913, when one 

 was seen eating a partly decayed fish. 



3. Larus delaivarensis. Ring-billed Gull. This species 

 seemed to be more uncommon than the Herring Gull. While on 

 several occasions there have been noted larger gulls which were 

 supposed to be ring-billed gulls the writer has only one positive 

 record, that of May 11, 1914, when a gull of this species in full 

 plumage and with the black ring on the liill distinctly visible, 

 was seen at close range.
