ANDERSON — THE BIRDS OF IOWA. 1 49 



Linn county as a " rare winter visitant" (G. H. Berry). Kum- 

 lien and Hollister report it as occurring sparingly as a migrant in 

 Wisconsin, remaining all winter where there is open water. It 

 has also been reported from Miiuiesota, once from Fillmore 

 county, near the Iowa line (Hatch). 



3. (3). Colynibus aiiriius Linn. Horned Grebe. 



The Horned Grebe was given as a rather connnon migrant in 

 Iowa by Keyes and Williams, Ijut it appears from the reports of 

 observers to be generally rare at present. The earliest record is 

 that of Thomas Say, " Colymbus cornutus. Arrived May 5, 

 1820, Engineers' Cantonment" (Long's Exp. to Rocky Mts. i, 

 266). Dr. B. H. Bailey has three specimens taken in a slough 

 near Cedar Rapids, showing three distinct phases of plumage: 

 April 19, 1903, male, full plumage; April 19, 1903, plumage 

 changing, head and neck mottled; Nov. 11, 1902, female, winter 

 plumage. The Horned Grebe was reported by Dr. Hvoslef as 

 breeding in the vicinity of Lanesboro, Fillmore county, near the 

 southern border of the state (Hatch, Bds. of Minn. 1892, p. 6). 



County records: Blackhawk — "occasional summer visitant, 

 nesting; specimen mounted by myself in I. S. N. S. Museum" 

 (Walters); "rare transient" (Salisbury). Cerro Gordo — "one 

 specimen April 6, 1890" (Richardson). Des Moines — (Bartsch). 

 Jackson — "common transient" (Giddings). Keokuk district — 

 "rare transient" (Praeger). Linn — (Bailey, Berry). Powe- 

 shiek — "rare transient" (Kelse}', Jones). • 



4. (4). Colymbus nioricol/is californiciis (Heerm.). American 

 Eared Grebe. 



This species appears to be somewhat locally and irregularly- 

 distributed in Iowa, although common at certain points. "It has 

 been found breeding in small numbers at West Point and Omaha" 

 (Rev. Bds. Neb., p. 17). 



County records: Hancock — Dr. B. H. Bailej- found this spe- 

 cies quite common at Eagle Lake, in July, 1902. They were 

 more common than the Pied-billed Grebe. Three adult speci- 

 mens were shot there July 18-19, 1902, and many were seen lead- 

 ing their young. He says: "I took eggs and also photographed 

 and shot birds in June, 1903." Potlawallamie — Mills — " coni-
