Semipalmated Sandpiper	Riverton Wildlife Management Area	Riverton W.A., Fremont Co.	feeding with other shorebirds on large mudflat area	The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Anotther documentation form by Ross Silcock was submitted later. \| Elimination of similar species: similar species eliminated above [...] This bird was slightly bigger than a Least and was much chunkier. The bird had dark legs, seen in direct comparison with the dark legs of Baird's Sandpipers and the yellowish legs of the Least Sandpipers. This bird was also still in basic plumage, making it much paler in color than the other peeps.

Marsh Wren	Browns Lake	Brown's L., Woodbury Co., IA	marsh with open water	The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. \| Elimination of similar species: Both birds were clearly wrens. I would have been very surprised if they had been any wren species other than Marsh or Sedge in this habitat. The combination of a white eyeline, dark mantle with thin white stripes, white throat and breast, and dark crown eliminated other wrens, especially Sedge Wren. I also recognized the chip note as that of a Marsh Wren. \| The original documentation form event lasted from 08:10:00/08:55:00.	Iowa Ornithologists' Union \| MS 166	13	2

Black cap eliminated those two plus Carolina and Bewick's Wren. The lack of crown streaking eliminated Sedge Wren.

Other observers include Peter C. Petersen and Jim Fuller. \| Elimination of similar species: Surf Scoter is another all dark bird, but it would have a much larger bill that extends on the same angle as a flattened forehead.

Black Scoter	Volga Lake	Northwest a rea [sic] of Volga Lake, in the Volga Lake Recreation Area, Fayette County, Iowa.		The documentation form by Joe Schaufenbuel is the only one submitted and forms the basis of this record. \| Elimination of similar species: The only bird that this duck reminded me of was a Ruddy Duck female, but this bird was difinitely [sic] not this species, and is mentioned because of vague plumage characteristic similarities. \| The original documentation form event lasted from 13:20:00/14:45:00.

Other documentation forms by Mark Proescholdt and Ann Johnson were submitted later. Other observers include Gladys Black, Tim Schantz, Pam Allen, Reid Allen, and unidentified other observers. \| Elimination of similar species: The thin bill was not that of a vireo. The bird was too large and elongated for a kinglet. Orange-crowned Warbler does not have wing bars or as bright a yellow color on breast. Also too yellow for the much less likely Bay-breasted or Blackpoll Warblers. \| The original documentation form event lasted from 08:30:00Z/08:33:00Z.	Iowa Ornithologists' Union \| MS 166	13	20

The documentation form by Jim Fuller forms the basis of this record. Other documentation forms by Thomas H. Kent and Randall Pinkston were submitted. Other observers include Carl Bendorf, Dick Teterault, Jim Scheib, Matt Prather, and many unidentified observers. \| Elimination of similar species: The combination of light eye ring, whitish wingbars, unstreaked back, and light belly and vent should separate this species from any other warbler. \| The original documentation form event lasted from 08:55:00/09:20:00 and 12:55:00/13:00:00.

The lake was half frozen two days ago, but two warm days made it ice free.	The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. \| Elimination of similar species: The short legs and large rounded head with thick neck are the main features that distinguish immature Black-crowned from Yellow-crowned Night-Herons. The round white dots on the upper wing are supposed to be more prominent on the Black-crowned, but this is difficult for me to judge. \| The original documentation form event lasted from 13:05:00/13:30:00.

Another documentation form by Stephen J. Dinsmore was submitted later.
