Records Committee review for rare bird sighting for Northern Shrike near Battle Creek, 1990	Administrative records Field notes	Bird watching Ornithology Ornithology--Societies, etc	1990-07-15	1993-07-17	Rare birds documentation form	Records Committee review for a Northern Shrike near Battle Creek in Ida County, IA on July 15, 1990. Includes a record review document with votes and a documentation form submitted to the committee.	DeVore, Dawn L.	Northern Shrike	Battle Creek	Block 376 Ida County, 2.3 miles South on county pavement, South of Battle Creek, turn 1/2 mile East, turn North into field-lane, Ida County, Iowa.	Open farm land, a hay field on one side, and a corn field on the other side. The bird was along a fence row.	The documentation form by Dawn L. De Vore is the only one submitted and forms the basis of this record. Other observers include Don Poggensee and Pam Poggensee. \| Elimination of similar species: Loggerhead Shrike: On the bird that was seen the top of the bill was dark black and the bottom was a lighter in color. A Loggerhead has a completely black bill. The bird that was seen was a light gray, much lighter than a Loggerhead adult. The bird was not a juv. Loggerhead because the black patch on the head is very different than that of a Loggerhead. On a Loggerhead the black area or patch is very wide and runs along both over and under the eye, it also continues back toward the back of the head meeting up with the gray on the back of the birds head. On the bird that was seen the black area or patch did not run both over and under the eye, it only ran under the eye. Also the patch did not meet up with the gray on the back of the birds head, the black area was surrounded on three sides by white, never letting the black meet up with the gray. \| The original documentation form event lasted from approximately 15:00:00/15:10:00.

Quinn is the only one submitted and forms the basis of this record. Another observer was Robert J. Naisbitt. \| Elimination of similar species: [...] This cap was quite noticeable & large (much larger than a catbird's cap). The bird seemed to be a little larger than a catbird (I have a pair nesting in my yard to [sic] I seem them a lot) and not as large as a robin. [...] He put me in mind very much of a catbird in size and contours. \| The original documentation form event lasted around "evenings and 1 morning" from around May 22 to the first week of June 1990.

Ave. Nevada, Iowa 50201		The documentation form by Bill Abbott is the only one submitted and forms the basis of this record. \| Elimination of similar species: The fact this bird was sighted on May 21 and 22 makes it very unlikely an immature Rose breasted grosbeak. The red patch shown on the shoulder of an immature grosbeak was not observed. The breast on the bird observed was not as spotted or steaked [sic] as shown on the female rose breasted grosbeak. \| The original documentation form event occurred around 18:00:00 on May 21 and 07:00:00 on May 22.

Records Committee review for rare bird sighting of Mississippi Kite at Coralville Reservoir, 1990	Administrative records Clippings (information artifacts) Field notes	Bird watching Ornithology Ornithology--Societies, etc	1990-05-19	1993-07-17	Rare birds documentation form	Records Committee review of a Mississippi Kite at Coralville Reservoir in Johnson County, IA on May 19, 1990. Includes a record review document with votes, an article in Iowa Bird Life, and a documentation form submitted to the committee.	Kent, Thomas H. (Thomas Hugh), 1934-	Mississippi Kite	Babcock Access	Coraville Reservoir, Babcock Access, Johnson Co., IA	wide part of reservoir with open mud flats	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 pointed wings indicate a kite or falcon. The gliding flight was that of a kite not a falcon. The white body and head also eliminates all falcons. The lack of white rump as well as the flight pattern eliminate Northern Harrier. Swallow-tailed Kite would have a forked tail and different flight pattern. Black-shouldered Kite has a white and black shoulder. The lack of white patches in the secondaries and brownish tail indicate a subadult (first year bird). I looked for bands in the tail, but could not appreciate them. Failure to see bands could be due to the lighting and distance or, as noted by Clark and Wheeler, to the fact that "A few immatures have solid, unbanded dark brown tails." The prominent light and dark underwing puzzled me, but Dunne says that "Immature has body and underwing coverts buffy, with dark streaking and spotting of variable density; may be lighter or darker than illustrated." The underwing coverts and body appeared about the same shade to me. The lighting and distance may have precluded my appreciating any streaking. This bird appeared lighter than the bird I saw at Dudgeon Lake last year, especially the underwing coverts. The profile and flight characteristics allowed me to immediately recognize the bird as a Mississippi Kite. \| The original documentation form event lasted from 13:35:00/13:36:00.

Sinclair, Jim	Mississippi Kite	Ledges State Park	Ledges St. Pk. - Pea's Creek	wooded valley	The documentation form by Jim Sinclair is the earliest and the one that forms the basis of this record.

Includes a record review document with votes and a documentation form submitted to the committee.	Blevins, Brian L.	Smew	Pool 13	Pool 13 on Mississippi River (Gomer's Lake, Potter's Marsh) Clinton County, Ia Carrol County, Ill.	The bird was in a big river pool situation with hundreds of other divers mostly comprising of Redheads, Scaup, Buffleheads, and Goldeneyes. This particular area offers large extensive flats adjacent to both sides of the channel.	The documentation form by Brian Blevins is the only one submitted and forms the basis of this record. Another observer was Corey Blevins. \| Elimination of similar species: About the only thing that is close is the Bufflehead and they were feeding with this bird, thus contrasting them was easy. The head difference was unmistakable with the buffs having an all dark head with a white spot, where as the smew had a white head with a black patch. \| The original documentation form event lasted from 15:13:00/15:36:00.

Records Committee review for rare bird sighting of Laughing Gull at Oak Grove Beach at Saylorville Reservoir, 1990	Administrative records Field notes Photographs	Bird watching Ornithology Ornithology--Societies, etc	1990-04-13	1993-07-17	Rare birds documentation form	Records Committee review of a Laughing Gull at Oak Grove Beach at Saylorville Reservoir in Polk County, IA on April 13, 1990. Includes a record review document with votes, a photocopy of a photo, and a documentation form submitted to the committee.	Dinsmore, Stephen J.	Laughing Gull	Oak Grove Recreation Area	Oak Grove Beach, Saylorville Reservoir, Polk Co., IA		The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include Eugene Armstrong and Eloise Armstrong. \| Elimination of similar species: On the basis of the dark hood, size, and dark gray mantle, all gulls except for Laughing and Franklin's gulls can be removed from consideration. I will admit that I was skeptical that a Laughing Gull could show up in Iowa on such an early spring date; most interior records are from May-June. But, given the evidence, I am convinced that this bird was indeed a Laughing Gull. The size of this bird, nearly that of a ring-billed gull, favors Laughing Gull. The bill shape and size, length of the legs, wing pattern, and extent of the eye crescents also favor Laughing Gull. An adult Franklin's Gull can be eliminated by the lack of a white bar separating the gray inner wing from the black wingtip. One year-old Franklin's Gulls, however, may show a wing pattern like that of this bird. But, according to Kaufman (1990), such a Franklin's Gull should show some white flecks on the hood, and would be most likely encountered in late spring and summer. \| The original documentation form event lasted from 10:48:00/11:34:00 and 12:26:00/13:20:00.
