That bird has never been seen away from that area, and should be noticeably larger than a Lesser black backed gull. The European race of the Herring gull has yellow legs, and one has been seen on the east coast the past two winters. That bird should be larger, and does not have a dark mantle. \| The original documentation form event lasted from 14:03:00/14:27:00.	Iowa Ornithologists' Union \| MS 166	11	5
Records Committee review for rare bird sighting of California Gull at Mini-Wakan State Park, 1996	Administrative records Clippings (information artifacts) Field notes	Bird watching Ornithology Ornithology--Societies, etc	1996-09-06	2000-11-22	Rare birds documentation form	Records Committee review for a California Gull at Mini-Wakan State Park in Dickinson County, IA on September 6, 1996. Includes a record review document with votes, an article in Iowa Bird Life, and a documentation form submitted to the committee.	Bangma, Jim Johnson, Ann	California Gull	Mini Wakan State Park	Spirit Lake, north end, Dickinson Co., IA	Lakeshore	The documentation form by Jim Bangma and Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Ring-billed is ruled out by the solid gray mantle combined with the extensive molt of the flight feathers. Ring-bills and similar 3 year gulls obtain the gray mantle during a post-juvenal molt. Flight feathers are not molted at this time. Flight feathers are molted after one year, at which time the body of a Ring-bill would be much whiter. Also, the mantle was a much darker shade of gray than any Ring-bill present. Additionally, Ring-billed Gull's bill is proportionally smaller and thinner, with more curve. Herring Gull would be larger. The mantle of a Herring Gull would be paler gray, nearly the same shade as that of the Ring-bills. The bill would be proportionally heavier with a more marked gonydeal angle. Herring Gulls may show a black tipped bill, but the black normally blends into the pink of the base or runs in along the cutting edges of the bill. The bill and legs would be brighter pink. Other similarly sized extralimitals can be ruled out by the mantle color as well as bill pattern and shape. A striking feature of this bird was its leg length. In an effort to better understand this, Bangma paid a visit to the American Museum of Natural History and examined specimens of Herring, Ring-billed and California Gulls. Measurements were made of a representative selection of specimens. The following chart shows the results. [Chart] While there is some overlap between these species, it is interesting to note that the breaking point between California Gull and the other two is very near the ratio of 1.5. While not diagnostic by itself, the length of this bird's tarsus relative to the culmen as estimated by us in the field is indicative of California Gull. \| The original documentation form event lasted from 11:00:00/11:40:00.

Records Committee review for rare bird sighting of Great Cormorant at Rice Lake, 1996	Administrative records Field notes	Bird watching Ornithology Ornithology--Societies, etc	1996-09-08	2000-11-22	Rare birds documentation form	Records Committee review for a Great Cormorant at Rice Lake in Worth County, IA on September 8, 1996. Includes a record review document with votes and two documentation forms submitted to the committee.	Bangma, Jim	Great Cormorant	Rice Lake	Rice Lake	Lake	The documentation form by Jim Bangma is the earliest and the one that forms the basis of this record. Another documentation form by Ann Johnson was submitted later. \| Elimination of similar species: Double-crested is smaller, with a much thinner neck. There is a noticeable transition from the thin neck to the larger head. In this bird, there was no noticeable widening from the neck to the head. Additionally, Double-crested has a proportionally much smaller and weaker bill. Double-crested's forehead slopes more evenly into the bill. While these differences may be difficult to see in single birds without comparative experience, in direct comparison they are significant. Additionally, the orange facial skin combines with the gular pouch to accentuate the overall orange color of the face. Other extralimital black cormorants can be ruled out on size alone, additionally, most have thinner necks and smaller bills than even Double-crested. \| The original documentation form event lasted from 11:00:00/11:02:00.

Rare bird documentation form for Red-throated Loon at Saylorville Reservoir, 1999	Field notes	Birds--Identification Ornithology Rare birds	1999-11-07	N/A	Rare birds documentation form	Rare bird documentation form for two Red-throated Loons at Saylorville Reservoir in Polk County, IA on November 7, 1999.	Dinsmore, James J.	Red-throated Loon	Saylorville Dam	Saylorville Reservoir, off of west end of dam	freshwater lake	The documentation form by Jim Dinsmore is the only one submitted and forms the basis of this record. Other observers include Bery Engebretsen and Dennis Thompson. \| Elimination of similar species: I spent a long time puzzling over these birds, both in the field and later when I had several references to consult. None of the guides I looked at showed a bird that looked like these. Common (a small one): removed on the basis of size (birds too small for Common Loon), the thinner and bicolored bill, and the color pattern on the neck. At this time of year, all of the Common Loons I have seen (and saw on Saylorville that day) were distinctly white on the front of the neck with some partial bands of brown extending back in to the white. Pacific Loon: Eliminated on behavior (head posture), lack of a distinct dark/white line along the side of the neck, lack of chin straps across neck, and presence of brown on front of neck. Also the gray/brown contrast between neck and back would point away from Pacific but not eliminate it. Red-throated Loon: This is what I first thought the birds were but as I viewed them, I convinced myself several times that they were Pacific Loons. However, the combination of characters listed above seem to eliminate the other two possible species and also are positive characters for the Red-throated Loon. One character that puzzled me was the size of the bill. At least some of the guides (Advanced Birding esp) show the Red-throated Loon as having a tiny bill, much smaller than on this bird but those illustrations do not match those in other guides which emphasize more the shape of the bill than the size. \| The original documentation form event lasted from 07:45:00/08:45:00.
