|
Open water near shore. The Loon was first noticed as it swam side by side with a Common Loon.
|
The documentation form by Ray Cummins is the only one submitted and forms the basis of this record. | Elimination of similar species: The Loon was slightly smaller, with a gray crown and nape compared to it's darker back. The Common Loon nape was the same color as its back. The eye was in the dark crown area unlike the Common Loon which showed white over the eye. [...] The bill was smaller than the Common's and straight. [...] Red-throated Loon would hold it's bill upturned not straight. | The original documentation form event lasted from 10:00:00/10:15:00.

Sandy beach with about 50 other gulls including Ring-billed, Franklin's, Bonaparte's and the 1st winter Mew Gull. After about 20 min the bird departed to the north with about a dozen other gulls. Did not see them take off.
|
The documentation form by Ray Cummins is the only one submitted and forms the basis of this record. | Elimination of similar species: See Ring-billed Gull comparicons [sic] above. [...] The size was slightly but noticeably smaller than all the Ring-billeds present. The head was more rounded in appearance than the ring-billeds. The bill was smaller in portion than the Ring-billeds, both shorter and thinner. [...] The tail was black, but not as black as side by side comparisons with the adult Ring-billeds. | The original documentation form event lasted from 07:45:00/08:05:00.

The documentation form by Raymond Cummins is the only one submitted and forms the basis of this record. | Elimination of similar species: Of the medium sized Gulls only Ring-billed, Franklin's, and Mew Gulls have similar juvenile plumages. The direct size comparison, seen gull being smaller, bill shape and dark color, and lack of white in head eliminates Ring-billed Gull. Mew Gull is eliminated by long dark bill, Ring-billed like jist of bird in flight, and uniform overall color. The long down turned bill and the total improbability of a juvenile Franklin's being in southern Iowa on this date. | The original documentation form event lasted from 10:19:00/10:30:30 on June 4, 1991 and 09:30:00/09:35:00 on June 5, 1991.

Rose, and four unidentified other observers. | Elimination of similar species: The above description separates by direct comparison first-year Thayer's and Herring Gulls, the most similar species present. Thayer's may be confused in first year plumage with Kumlien's form of Iceland Gull, but the Thayer's had primaries slightly darker than the mantle (from above), whereas the opposite occurs in Iceland Gull (Lehman). Lehman also notes that some first-year Western Gulls may show translucent primaries from below in certain light, but these observations took place in excellent light at fairly close range. | The original documentation form event lasted from approximately 09:30:00/11:00:00.

The bird had some similarities to a Western Grebe, but the grebe would hold its head parallel to the water, has a longer neck, and does not show the contrast between head/nape and back. Common Loon was eliminated by posture, size and shape of bill, contrast of lighter head and darker back, and more diffuse separation of upper and underparts. Pacific Loon was eliminated by the grayer underparts, diffuse separation of upper and underparts, posture, and sharp upward angle on lower mandible. | The original documentation form event lasted from 11:50:00/12:15:00.

Larger than Ring-billed Gulls- flock of 14 adjacent. [...] Headmuch [sic] smaller relative to body than in the Herring Gull- also flatter-appearing. [...] 1. Bill was black (or very dark); this , combined with the rather pale underparts relative to the rest of the (also rather pale) plumage tends to rule out a first year Herring Gull. 2. Bill and head size and shape were not as heavy-appearing as in Herring Gull. Direct comparison with adjacent adult Herring Gull was very useful in deciding this. [...] 5. Size and pinker legs than Herring Gull are not sure characters, but lend support to identification as Thayer's Gull.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include William R. Clark. | Elimination of similar species: The size, neck pattern, bill shape, and chinstrap eliminate other species of loons. | The original documentation form event lasted from 16:20:00/16:45:00.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: Cormorants are the only birds likely to be confused with an Anhinga. I have seen thousands of Double-crested Cormorants and I have never seen one soar in this manner. Also, a Double-created Cormorant has a neck which is always longer than the tail (in flight) and looks conspicuously large-headed and thick-necked when seen overhead. Neotropic Cormorant is much smaller and, although it is longer-tailed than a Double-crested, the tail is still shorter than the neck in flight. | The original documentation form event lasted from 16:42:00/16:50:00.

The documentation form by Bob Myers forms the basis of this record. Other documentation forms by Steve Dinsmore, Ann Johnson, and Jim Fuller were submitted. Other observers include Beth Brown, James Dinsmore, L. Paul Hertzel, Eugene Armstrong, Eloise Armstrong, and many unidentified other observers. | Elimination of similar species: Eastern bluebird would show reddish on throat and breast. Western bluebirds would be darker and also have chestnut on breast. | The original documentation form event lasted from 10:00:00/10:30:00.

The documentation form by Ann Johnson is the earliest and the one that forms the basis of this record. Other documentation forms by Thomas H. Kent, Jim Fuller, and Brian Blevins were submitted later. Other observers include Ross Silcock, Peter Petersen, Kelly McKay, Corey Blevins, Jim Scheib, Jim Sinclair, John Daniel, Tim Schantz, Cal Knight, Bernie Knight, Chuck Fuller, David Youngblut, Beth Brown, Sherry Dragula, Bill Overland, Jane Overland, John Miller, Eugene Armstrong, Eloise Armstrong, and unidentified other observers. | Elimination of similar species: The date of observation is historically good for a vagrant western flycatcher species, so this was in the back of my mind in assessing the characteristics observed. The presence of both eye ring and wing bars, in addition to size and shape, indicate that the bird fits the Empidonax complex. The combination of green back, yellow throat and pure orange lower mandible with no markings would eliminate Least, Hammond's, Dusky, Gray, Buff-breasted, Alder, and Willow Flycatchers. A juvenile Acadian can be eliminated by the short primary extension, color of the wings, size and shape of the eye ring, and active behavior. Only three species are indicated by the green upper parts and yellow under parts. Two are separable only by voice. The choices were between Yellow-bellied Flycatcher and Western (Cordilleran and Pacific-slope) Flycatcher. Back color is greener in Yellow-bellied and more olive in Western. Although the back looked olive, this was rather subjective. According to the Audubon Master Guide, behavior would be more indicative of a Yellow-bellied in that the bird was not flicking both tail and wings. According to Kaufman, however, behavior is quite variable. Three characteristics made me lean more toward Western complex. They were peaked appearance to the head (usually smooth and rounded in Yellow-bellied); almond-shaped eye ring (round, narrow, and more even in Yellow-bellied); and browner wings than eastern Empidonax. The color of the wings is again subjective, but the contrast between wing color and wing bars was less than the black/white (or even black/buff in fall birds) of eastern birds. Even with the variability that may occur in any Empidonax, it is unlikely that these three characteristics, which are common to the Western Flycatcher, would appear simultaneously in a Yellow-bellied Flycatcher. Further support is found in the Audubon Master Guide to Birding where it states in the description of Western Flycatcher, "...olive wash on the breast, flanks, and especially the sides tends to highlight a midventral yellow stripe" - one of the more obvious characteristics when viewed at close range from the front. IF the call notes heard belonged to this bird, it would indicate a Cordilleran Flycatacher, the most likely vagrant. None of us were able, however, to get the bird to call as we were observing it. Cal Knight played a tape and the bird became very agitated but did not call. | The original documentation form event lasted from 11:00:00/14:00:00 on November 14, 1992 and 11:30:00/13:45:00 on November 15, 1992.
