Other documentation forms by Pam Allen and Thomas H. Kent were submitted later. Other observers include Reid Allen, W. Ross Silcock, and Dick Tetrault. \| Elimination of similar species: Identification of a Black-necked Stilt is straight forward. The only other bird in North America which is even remotely similar is the American Avocet. It can be eliminated by the black feathering on the head and neck, straight bill, and pink legs. \| The original documentation form event lasted from 14:55:00/16:55:00.

Park - (North Hardin County)	Brushy tangle along park's edge up the hill from Iowa River Greenbelt	The documentation form by Mark Proescholdt is the only one submitted and forms the basis of this record. \| Elimination of similar species: In "Spring" this should not be mistaken for any other warbler. A ♂ Mourning Warbler lacks the vivid eye crescents. A Connecticut Warbler has a complete white eyering and no black smudge on the upper breast and the gray head is a lighter gray color. In "fall" the female and immature Mourning Warblers may show a thin, nearly complete eyering (which I have seen on Mournings in the fall), but this could not be mistaken for the vivid white eye crescents of this breeding-plumaged male MacGillivray's Warbler along with its very noticeable black smudge on its upper breast below its gray hood. \| The original documentation form event lasted from approximately 11:15:00/11:15:05.

Marsh Wren	New Lake	New Lake, Woodbury County, IA	Cattail marsh with open water	The documentation form by Bill Huser is the only one submitted and forms the basis of this record. Another observer was Shawn Pfautsch. \| Elimination of similar species: Call note and appearance indicated a wren. White supercilliary eliminated House Wren and Winter Wren. Black cap eliminated those two plus Carolina and Bewick's Wren. The lack of crown streaking eliminated Sedge Wren. Habitat was a strong indicator of Marsh Wren and a detraction from all others except, perhaps, a Sedge Wren. \| The original documentation form event occurred around 11:00:00.
