Iceland Gull
|
Lock and Dam 15
|
Location: Davenport. County: Scott
|
General: Chanel [sic] of Miss. R., near middle of river when standing. Specific: 1/2 - 3/4 mi. above Lock + Dam 15.
|
The documentation form by Peter C. Petersen forms the basis of this record. Other documentation forms by Ann Barker, Mary Lou Petersen, and Bill Barker were submitted. Other observers include Steve Dinsmore, Paul Martsching, Pete Wickham, Mark Brogie, Lewis Blevins, Corey Blevins, Brett Ashford, and Dale Dickinson. | Elimination of similar species: Glaucous Gull eliminated by size, wing extention [sic] well beyond tail. Flight, headshape, all emphasized by direct comparison with Glaucous Gulls. The next afternoon Bill Barker compared this bird to two different sized Glaucous Gulls and it was smaller than the smaller Glaucous Gull. Plumage lighter than Glaucous also. | The original documentation form event lasted from 11:40:00/12:10:00.

Iceland Gull
|
Le Claire
|
[...] along the Mississippi River approximately one-half mile north of the Interstate 80 bridge in Scott County, Iowa.
|
|
The documentation form by Mark Brogie and Peter P. Wickham forms the basis of this record. Another documentation form by Paul Martsching was submitted. Another observer includes Steve Dinsmore. | Elimination of similar species: [...] The bird was in the company of several Herring Gulls (Larus argentatus) and three subadult Glaucous Gulls (Larus hyperboreus). Two of the Glaucous Gulls were light plumaged birds lacking a gray mantle and, since eye color was not noted, may have been either first or early second winter birds. The third Glaucous was quite buffy and was undoubtably [sic] a first winter bird. The Iceland Gull was first observed being chased by a light-phased Glaucous and was distinctly smaller and lighter colored. It also flew with a faster wingbeat and had a more buoyant flight than that of the larger bird. Glaucous Gulls were also observed chasing Herring Gulls but at no time was intraspecific chasing observed. During several instances two Glaucous Gulls were observed resting on the water or sitting on the ice together, but the Iceland always remained isolated from these birds. At one point the Iceland Gull circled overhead at a distance of approximately 40 yards in the company of a light-phased Glaucous and an immature Herring Gull, and characteristics between the species were well noted. The plumage of the Iceland was wholly white with a faint buffy tinge, yet distinctly whiter than the Glaucous Gull. The size difference between the Glaucous and the other two species was apparent as the Iceland and Herring were of approximately equal size. The head and bill of the Iceland Gull appeared less robust in shape than the Glaucous although both species had a bicolored bill with a flesh colored base and dark tip. [...] The brown barring of the undertail coverts of the Iceland appeared heavier and more noticable [sic] than in its white-winged congeneric counterpart, and contrasted particularly with the whitish tail. | The original documentation form event lasted for approximately twenty minutes.

Other observers include Dawn DeVore, Dick Tetrault, Jim Scheib, Beth Brown, Michael Porter, Eugene Armstrong, Eloise Armstrong, and many unidentified observers. | Elimination of similar species: [...] Iowa Birds mentions that there is a problem separating Iceland with Thayers. If there was any problem with this bird being anything it was a Glaucous Gull of the same age. However the bird was smaller than the Herring Gulls that were on the roost. Long wings will rule out the rare small race of Glaucous Gull. There are not to [sic] many birds that have primaries lighter than the mantle in the sitting bird.

The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. Another documentation form by Jim Fuller was submitted later. Other observers include Pete Wickham, John Daniel, Chuck Fuller, Bill Dawes, and John Rutenbeck. | Elimination of similar species: At first I thought the bird might be a Glaucous Gull, but the all black bill quickly excluded that possibility. Later I confirmed that the bird was smaller than Herrings and had a bill that was too small and too short for a Glaucous. I believe that the tail band also argues against Glaucous. I next considered Thayer's Gull, but decided that the tail band was not extensive enough, that there was no secondary bar, that the wing tips were too light (both in flight and on the standing bird), and that the tertials were not dark enough on the standing bird. All of the findings were a good fit for first-winter Iceland Gull. | The original documentation form event lasted from 13:15:00/13:35:00 on December 31, 1991 and 08:55:00/10:20:00 on January 1, 1992.

I excluded Thayer's Gull because both of these birds had very light primaries (not dark webs on the outer primaries). Neither had a secondary bar or in fact any distinctive marking on the wings. The lack of tail band in the first year bird also excludes Thayer's Gull. I was impressed by the paleness of the gray mantle in the second-year bird, but have too little experience with older Thayer's Gulls to make a comparison. | The original documentation form event lasted from 11:30:00/12:30:00.

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.

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.

Another observer includes Chuck Fuller. | Elimination of similar species: The three most similar species are Herring, Thayer's, and Glaucous gulls in first-basic plumage. The latter was eliminated by its larger size and longer, heavier, bicolored bill. First-basic Herring Gull is much darker overall with primaries darker than the upperwing coverts, a pale window on the inner primaries, and rectrices that are all black. First-basic Thayer's Gull is the hardest to eliminate. Thayer's always show primaries that are as dark or darker than the rest of the wing. The dark tail band of Thayer's is always darker than the mantle and apparently matches the color of the wingtips (Kaufman 1990). | The original documentation form event lasted from 11:30:00/13:10:00.

Iceland Gull

Muscatine
|
On the Mississippi River approximately three miles south of Lock 16.

The documentation by Gerald White is the only one submitted and forms the basis of this record. Other observers include Betty Wood and Keith Blunt. | Elimination of similar species: [...] The bill appeared smaller than the bills of near-by Herring Gulls. The bird size was near the same size or smaller than the Herring Gulls. [...] I eliminated Glaucous Gull because it would have been larger and heavier looking and the bill would not have been all dark. | The original documentation form event lasted from 11:50:00/11:52:00.

The documentation form by Mark Proescholdt forms the basis of this record. Other documentation forms by Michael D. Overton and Stephen J. Dinsmore were submitted. Other observers include Kay Niyo, Curt Nelson, Jan Walter, Chris Wood, and Jim Sandrock. | Elimination of similar species: [...] We saw this gull twice in our viewing time and debated if it was an adult Kumlien's Iceland Gull or an adult Thayer's Gull. It was an adult Kumlien's Iceland Gull because a Thayer's Gull has much more blackish coloration at the primary tips and more dark coloration at the primary tips than the Kumlien's which has grayish markings on the primary tips and less dark-colored markings at the primary tips overall. Also, a Kumlien's Iceland Gull shows the almost white wing tips like we saw with a little grayish markings on some primary tips. | The original documentation form event lasted from approximately 15:00:00/16:15:00.
