Lesser Black-backed Gull

Coralville Lake

Coralville Reservoir, Johnson Co., IA.
|
Reservoir mostly ice-covered. Gulls around small patch of open water.
|
The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Jim Fuller was another observer. | Elimination of similar species: The size, wing and mantle color and yellow legs exclude other species, except perhaps for the most unlikely Yellow-footed Gull, which should be larger. | The original documentation form event lasted from 08:45:00/09:00:00.

The documentation form by Dave Carlisle is the only one submitted and forms the basis of this record. | Elimination of similar species: [...] In my attempts to identify the birds, my first observations led me to believe they both were wrens; however, they were larger than the common house wren and lacked the definite light eye ring. [...] I took notice that the bird in hand lacked the definite eye stripe characteristic of the Bewick's, Carolina, and Marsh wrens. There were no white stripes on the back as in the Marsh Wren and it did not have the white outer tail feathers characteristic of Bewick's Wren. | The original documentation form event occurred lasted from approximately 07:50:00/08:00:00.

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.

The documentation form by Ann Johnson forms the basis of this record. Another documentation form by Tim Schantz was submitted. Other observers include Roy Godwin and Jim Sinclair. | Elimination of similar species: Body and bill shape and behavior identified this bird as a flycatcher. The size, eye-ring and wing bars eliminated all but Empidonax flycatchers. Because of the late date on this bird, it is difficult to get an understanding of molt sequences which may or may not be helpful. From what I can find on molts, however, the following is based on best available information. | The original documentation form event lasted from 11:40:00/11:55:00 and approximately 13:30:00/14:00:00.

Another observer was John Rutenbeck. | Elimination of similar species: Great-tailed grackle - as described. [...] Two things were apparent: On profile the head and particularly the bill were that of an ani and not of a grackle. [...] One other note - When I first flushed the bird it made a startled cry. This cry was very similar, if not identical to the last part of the Groove-billed Ani call on Peterson's Field Guide to Western Birds record. Conclusion ani sp. probably a Groove-Billed | The original documentation form event lasted from 14:45:00/15:30:00 and 15:45:00/16:15:00.

The Inca dove does have scaling, but it has a longer tail, an entirely black bill, has a light belly with black stripes, and lacks the black spots on the folded wing. | The original documentation form event lasted from 13:40:00/14:50:00.

Another observer was Brian Warson. | Elimination of similar species: The bird was clearly an alcid. The small size rules out the murres, Razorbill, and guillemots (see earlier discussion). The long, thin bill eliminates Dovekie, Ancient Murrelet, and all of the auklets. The bill shape, dark cap that included the eye, and presence of two white patches on each side eliminates all other murrelets, especially Kittlitz's. | The original documentation form event lasted from 15:15:00/15:24:00.

The documentation form by Ann Johnson forms the basis of this record. Another documentation form by Thomas H. Kent was submitted. Other observers include Jim Fuller, Dick Tetrault, and Tim Schantz. | Elimination of similar species: Herring Gull was eliminated by the light and uniform body color, pale gray primaries, secondaries and tailband, lack of a window from above, and lack of any color to the underside of the primaries. The bird certainly had the overall coloration of a first year Iceland Gull. However, Iceland Gull was eliminated based on the darker secondaries, complete gray tail band, and the darker webs to the outer primaries from above. | The original documentation form event lasted from 16:10:00/16:50:00 on November 25, 1991 and 13:50:00/14:05:00 on November 28, 1991.

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.

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.

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.
