Rare bird documentation form for Long-tailed Duck at Lake Manawa, 1988	Field notes	Birds--Identification Ornithology Rare birds	1988-10-24	1988-10-27	Rare birds documentation form	Rare bird documentation form for a Long-tailed Duck at Lake Manawa in Pottawattamie County, IA on October 24, 1988.	Grenon, Alan G.	Long-tailed Duck	Lake Manawa	west-central part of Lake Manawa, Pottawattamie County, Iowa	open water and the air over open water	The documentation form by Alan Grenon is the only one submitted and forms the basis of this record. Other observers include Babs Padelford, Loren Padelford, Ruth Green, Betty Grenon, and Bruce Wetteroth. \| Elimination of similar species: This duck was similar in size or slightly larger than nearby Lesser Scaup; most of the bird was a brown slightly lighter than female Lesser Scaup, and without mottling patters. Among ducks that have considerable white on the face, few have white around the eye and extending back to the nape. This eliminates the scoters (also, the bill did not seem large or deep enough for most scoters), Harlequin Duck, Bufflehead, goldeneyes, Smew, scaup, and Northern Pintail (which might have a similar plumage, but with white lower on the neck and side of neck, patterning on the body, speculum, and more differences). Unmarked bill and wing eliminate aberrant Ring-necked Duck and scaup, respectively, and also other divers with contrasting wing markings (including Bufflehead, goldeneyes). The possibility of an aberrant Harlequin Duck exists, but that seems less likely than a young Long-tailed Duck at this location. \| The original documentation form event lasted from 10:15:00/11:15:00 and 17:00:00/18:15:00.
