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.

Includes a record review document with votes, an article in Iowa Bird Life, and three documentations submitted to the committee.	Johnson, Ann	Mew Gull	Whitebreast Recreation Area	Whitebreast Recreation Area, Red Rock Reservoir, Marion Co., IA	Sandy area at edge of open water	The documentation form by Ann Johnson forms the basis of this record. Other documentation forms by Russ Widner and Jim Fuller were submitted. Other observers include Dick Tetrault and Roy Godwin. \| Elimination of similar species: Size eliminated any gull larger than a Ring-billed. Although structurally the bird more closely represented one of the larger hooded gulls, they were eliminated by the lack of any hood or auricular spot. Furthermore, most hooded gulls with a tail band would also show a strong carpal bar. Laughing Gull could be eliminated by the more diminuative [sic] bill and leg color. Although some individuals seem to carry a vestige of their more motley juvenile plumage into first winter, Ring-billed Gull was eliminated by size, head and bill structure, and clear-cut as opposed to more diffuse tail band. I originally identified this bird as a Mew Gull based on my experience studying structural differences between Ring-billed and Mew gulls on the west coast. I have never seen a first-year Mew Gull, however. In researching the Mew on my return home, I concluded that the bird in question was not dark enough, nor brown enough, to be of the west coast sub-species. By virtue of its strong similarity to a Ring-billed Gull, this bird was most likely the European sub-species known as the Common Gull. Although according to Grant the bill description comes closer to L.c. brachyrhynchus, I assume that this bird's bill coloration was still changing from juvenile plumage. Apparently the Common Gull appears on occasion on the east coast and is therefore probably as likely a vagrant to Iowa as is the western form. \| The original documentation form event lasted from 10:30:00/10:40:00.

Includes a record review document with votes and a documentation form submitted to the committee.	Johnson, Ann	Iceland Gull	Credit Island	Credit Island, Davenport, Scott County, IA	Frozen lagoon with small amount of open water	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Although the duskiness on the face had somewhat of a "hooded" effect, any of the hooded gulls could be eliminated by the bill structure. The pale primaries eliminated all but the white-winged gulls - Glaucous, Iceland, and possibly Thayer's. Glaucous can be eliminated by size and bill color. Thayer's was eliminated because of: 1) overall gray-white appearance; 2) the lack of any secondary bar; and 3) the checkered tertials. Problems with the record are the duskiness on the face and the narrow dark edging to the outer primaries from below. These two characteristics may well indicate an Iceland/Thayer's intergrade. \| The original documentation form event lasted from 13:15:00/13:40:00.	Iowa Ornithologists' Union \| MS 166	11	4

The documentation form by Jim Fuller is the only one submitted and forms the basis of this record. Another observer includes Jim Scheib. \| Elimination of similar species: This bird was much too small for a Glaucous Gull, and the generally whiter cast and two-toned bill would suggest a second-winter, compared to first-winter Iceland. \| The original documentation form event lasted from 14:55:00/15:00:00.

The Iceland Gull was sighted on the ice above the dam feeding on a dead Canada goose. It was very protective of the food source chasing Crows away.	The documentation form by Ray Cummins is the only one submitted and forms the basis of this record. Other observers include Mary Montgomery and Dot Cornett. \| Elimination of similar species: Thayer's Gull was eliminated because there was no dark in the primaries, no dark secondary band, and bill was not all dark. A first-winter Glaucous would have the coloration but there is no way this gulls bill or body size was big enough tobe [sic] a Gloucous [sic] Gull. \| The original documentation form event lasted from 09:45:00/10:30:00.

Another documentation form by Stephen J. Dinsmore was submitted later. Another observer includes Susan Grove. \| Elimination of similar species: I am uncomfortable committing to California Gull given the brief and distant view I had, and my limited past experience with the species. My fear is that this was just a small Herring Gull. Herring can be quite variable in overall size, bill size, and in terms of color and shade of the first-winter plumage. Supposedly 10-15% of first-winter Herrings' can have a "dipped-in-ink" bill in the fall (Harrison 1983 or Grant 1986?). \| The original documentation form event lasted from 12:30:00/15:30:00.

Johnson, Ann	Laughing Gull	Saylorville Dam	Below Saylorville Dam, Polk County, IA	Fast moving river with many small fish	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: The body and bill structure eliminated all but hooded gulls and the brown plumage indicated a first year bird. Size close to Ring-billed, in addition to plumage already described, eliminated some of the smaller hooded gulls. The most likely candidate for confusion would be the Franklin's Gull. Juvenile Franklin's shows a hooded pattern early in development rather than a brown wash on the head. Franklin's tail band would also be incomplete with white feathers showing on the outer edge. It would also show fewer dark primaries, with the inner flight feathers more approximating the mantle and inner wing color. No other small gull has this characteristic. \| The original documentation form event lasted from 11:45:00/12:10:00 and 15:30:00/14:00:00 [sic].	Iowa Ornithologists' Union \| MS 166	10	18

Other observers include Eugene Armstrong and Eloise Armstrong. \| Elimination of similar species: Bird flew & sat on ground next to Franklin's Gulls, and Bonaparte's gulls. Did not have white wedge of Bonapartes, Blackheaded or Sabine's Gull's. The other black-headed gull, the Little Gull, has no black at all on wing tips. See above for comparison to Franklin's. [...] Larger bill, compared to adjacent Franklin's, was not pure red, partially black.

A juvenile Mew gull is much darker, has a thin bill, and light grayish legs. Juvenile Herring and California Gulls are much larger - larger than Ring-Billed Gulls - and lack the bright white at the base of the tail. \| The original documentation form event lasted from approximately 09:00:00/09:15:00 and 11:00:00/12:10:00.

Other documentation forms by Maridel Jackson, Ross Silcock, Jane R. Clark, and Jim Sinclair were submitted later. Other observers include John Cecil, Eugene Armstrong, and Eloise Armstrong. \| Elimination of similar species: Northern Goshawk- Although Goshawks have been known to show pointed wings, they are never as pointed as a Falcon's. I have seen many Northern Goshawks and jizz alone would rule this one out. I saw no barring on the tail. One of the prime field marks on a Goshawk are the bright white undertail coverts which this bird did not have. The bird in question also lacked a dark crown. Peregrine Falcon- Size. No dark helmet. Jizz (mentioned above). The bird lacked overall contrast of a Peregrine Falcon. Juveniles would be brown. Prairie Falcon- Color. Prairies are a brown bird in all plumages. The underwing was uniform with no black axillaries. Habitat. Prairies feed almost exclusively on small mammals. \| The original documentation form event occurred around 15:30:00.
