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.
