Records Committee review for rare bird sighting of White-faced Ibis at Sheldon Basin, 1996	Administrative records Field notes	Bird watching Ornithology Ornithology--Societies, etc	1996-06-27	2000-11-22	Rare birds documentation form	Records Committee review for twelve White-faced Ibises at Sheldon Basin in Fremont County, IA on June 27, 1996.

Rare bird documentation form for Dunlin at Babcock Access in Coralville Reservoir, 1995	Field notes	Birds--Identification Ornithology Rare birds	1995-07-30	1995-07-31	Rare birds documentation form	Rare bird documentation form for a Dunlin at Babcock Access in Coralville Reservoir in Johnson County, IA on July 30, 1995.	Kent, Thomas H. (Thomas Hugh), 1934-	Dunlin	Babcock Access	Coralville Res., Babcock Access, Johnson Co., Iowa	mud flats	The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. \| Elimination of similar species: The bill and body proportions were those of a Dunlin, but the date and plumage were new for me. The streaks on the underparts, worn edging on some wing feathers, and eye line appear to be retained alternate features, while the lack of black on belly and rufous in wing are features of basic plumage. I assume that this was an adult partially molted to basic plumage. Although Dunlin is usually a late fall migrant, both Iowa and Minnesota have a few July records. According to Prater et al. (1977), nearctic birds molt before migrating; therefore, a bird in mostly basic plumage would not be unusual. White-rumped Sandpiper is exclude [sic] by the tail pattern, body proportions and bill length. Baird's Sandpiper has a shorter bill, longer tail/wing extension, slimmer profile, and browner and scaly upperparts. \| The original documentation form event lasted from 14:00:00/14:45:00 approximately.

Ernzen, Peter	Long-billed Curlew	Black Hawk Lake	dredge pond area southeast of Blackhawk Lake in Sac Co.		The documentation form by Peter Ernzen is the only one submitted and forms the basis of this record. Other observers include Joshua Ernzen. \| Elimination of similar species: [...] Whimbrel was eliminated by size, color and bill size. The whimbrel should have been slightly smaller to about the same size as the marbled godwits. The brown body and cinnamon wing linings did not fit whimbrel either. The bill size is variable with shorebirds, however the great length of the bill was more suggestive of the long billed curlew. The call heard does not fit the description for whimbrel in my National Geographics [sic] Field guide to Birds of North America. Three outside possibilities the far Eastern curlew, Eurasian curlew, and bristle thighed curlew were eliminated as well. The far Eastern curlew size is about the same as that of the marbled godwit. The bird also has white wing linings with dark barring. The barring would be hard to see, however the lighter color would be distinguishable. The Eurasion [sic] curlew was eliminated because this bird would have a white rump, and white wing linings. The bird I saw in flight turned and twisted. I did not notice any white markings on the rump. The bristle thighed curlew is much more similar to the smaller whimbrel and would be eliminated by small size, shorter bill and call - "chu-a-wut". \| The original documentation form event lasted from 19:50:00/20:00:00.
