Rare bird documentation form for Herring Gull at Red Rock Reservoir, 1991	Field notes	Birds--Identification Ornithology Rare birds	1991-01-04	1991-01-23	Rare birds documentation form	Rare bird documentation form for a Herring Gull at Red Rock Reservoir in Marion County, IA on January 4, 1991.	Kent, Thomas H. (Thomas Hugh), 1934-	Herring Gull	Lake Red Rock	Red Rock Reservoir, Marion County, Iowa	Des Moines River below dam, water mostly open with ice on edges	The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Other observers include Jim Fuller and Tim Barksdale. \| Elimination of similar species: The color of the back and obvious window in the inner primaries, as well as the rest of the feather tracts, all fit 2nd winter Herring Gull and seem to exclude Lesser Black-backed Gull. The soft parts were somewhat atypical, but I was not bothered much by this because I have seen much variation in Herring Gulls. \| The original documentation form event lasted from 08:10:00/08:25:00 and 12:45:00/13:00:00 (approximate)	Iowa Ornithologists' Union \| MS 166	34	34
Rare bird documentation form for Herring Gull at MidAmerican Energy Ponds near Council Bluffs, 1985	Field notes	Birds--Identification Ornithology Rare birds	1985-05-24	1985-06-03	Rare birds documentation form	Rare bird documentation form for a Herring Gull at MidAmerican Energy Ponds near Council Bluffs in Pottawattamie County, IA on May 24, 1985.	Wilson, Barbara L.	Herring Gull	MidAmerican Energy Ponds	IPL Settling Ponds, Council Bluffs, Iowa		The documentation form by Barb L. Wilson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Similar to most of the other large immature gulls of the world. Mantle too light for Black-backed group. Wingtips, even in their folded condition, too dark for Glaucous, Glaucous-winged, etc. that leaves a whole mess of light-mouthed large gulls with dark wing tips. Description seems to match young Herring Gull (second summer ?) well enough. Eye color would probably be becoming pale in a Herring of this plumage, but perhaps not, + it might not show at the distance. I have trouble eliminating California Gull, but it is even harder to support that species.	Iowa Ornithologists' Union \| MS 166	34	34
