|
Little Gull
|
Black Hawk Lake
|
[...] south east corner of Blackhawk Lake in Sac Co.
|
|
The documentation by Peter Ernzen forms the basis of this record. A documentation form by Jim Fuller was submitted. | Elimination of similar species: [...] The other five hooded gulls were eliminated for a variety of reasons. Franklin's and Laughing Gull would be larger, darker mantled and have a prominent eye ring. Sabine's Gull would've had a bicolored bill, forked tail and different - white triangular - pattern to its wings. The larger Common Black-headed Gull looks like a larger version of a Bonaparte's Gull with a brownish hood and a red bill. The associated Bonaparte's Gulls were darker mantled and larger. The wings were more angular in appearance with a white leading edge and black wing tips. I have observed all but the Laughing Gull - though the Sabine's Gulls were immature, the distinctive wing pattern is present in both adults and immatures - and feel confident in calling this an adult Little Gull. | The original documentation form event lasted from 10:15:00/10:30:00 and 11:00:00/11:08:00.

Another observer was Mark Sutter. | Elimination of similar species: [...] one characteristic had been very noticeable-the great amount of white color that flashed as the bird flew, both on the upper- and undersides of the wings. At the time I did not realize the importance of this detail, but I recorded it along with my other field notes as I knew from past reading that distinguishing between Long-tailed and Parasitic Jaegers could be tricky. | The original documentation form event occurred around 18:00:00.

|
|
The documentation by Peter Ernzen is the only one submitted and forms the basis of this record. | Elimination of similar species: [...] I initially thought that the bird was a Mourning Warbler - common at Moorehead Park at this time of the year in this type of habitat. [...] I observed a broken eye ring on both sides of the head of this bird. The broken eye ring could best be described as " two bold white crescents" - above and below the eye. The other feature which stuck in my mind was the relatively long looking - "longer looking than Mourning" - tail on this particular bird. At first I tried to dismiss this bird as a nontypical Mourning Warbler. I have seen on several occasions Mourning warblers with slight eye rings - making identification of fall Connecticut and irregular Mourning warblers somewhat difficult. For the next week I returned to the spot hoping for a glimpse of the bird. This proved useless. I had hoped to see this bird as my notes were rather sketchy and incomplete. Consisting primarily of "bird with 2 bold white crescents" around the eyes, and "appeared longer tailed than Mourning". Otherwise the bird looked very similar to a fall male mourning warlber [sic]. | The original documentation form event occurred in the afternoon and lasted around 10 seconds.

|
[...] Oak Grove Beach Recreation Area at Saylorville Reservoir, Polk County.
|
|
The article by Stephen J. Dinsmore forms the basis of this record. | Elimination of similar species: [...]The bird was similar in size to the largest Ring-billed Gulls, but slightly larger than others. I approached closer and noted that, when compared to a Ring-billed Gull, the bird had duller yellow legs, a stouter bill with black and red spots near the tip of the lower mandible, and a darker gray mantle. [...] The bird was slightly larger than most of the Ring-billed Gulls, although one or two of the biggest Ring-billed Gulls were as large as the bird I was studying. Proportionately, the bird was heavier and larger-headed than a Ring-billed Gull. [...] I estimated the mantle color to be about midway between those of Ring-billed Gull and a Lesser Black-backed Gull. [...] The bill was heavier than the bill of a Ring-billed Gull and had a distinct gonys. The legs were pale gray-green, unlike the bright yellow legs of a Ring-billed Gull. Leg length appeared similar to a Ring-billed Gull. | The original documentation form event lasted from 07:45:00/09:27:00.

[...] 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.

|
[...] Lake Manawa State Park, near Council Bluffs, IA. [...] was travelling south on the road that follows the west edge of Lake Manawa.
|
|
The documentation letter by Manit Bunnimit is the only one submitted and forms the basis of this record. | Elimination of similar species: [...] It flew for most of the time by soaring with its wings held very flat, only twice flapping its wings momentarily (shallow wingbeats) and once folding its wings rather tightly and gliding. All of the crows I have seen flap steadily, gliding only occasionally. [...] It could not have been mistaken even for the tails of the occasional American Crows that appear quite rounded. The sheer size of the bird and the wedge-shaped tail were enough to distinguish it from any of the crows, but what about the Chihuahuan Raven? Fortunately, as it flew by, the bird made two brief call notes that were very hoarse (sounding much more like grrrawgk than the gaw of the American Crow), and much deeper than the Chihuahuan Raven that I heard in northern Texas. However, because it has been a few years since I had seen or heard the Chihuahuan, I decided to double check the calls on a tape I had at home. The tape and I agree that the call was that of a Common Raven. | The original documentation form event lasted from approximately 11:10:00/11:11:00.

Upon returning home, however, we found in Bent, "The note of the Smooth-billed ani has been called a wailing or whining whistle - resembling the notes of the wood duck." Our bird's call note was not a whistle at all. And then we found in Pough's Eastern Land Birds under Smooth-billed ani, "The two anis are hard to tell apart except by note, the whining notes of this species being in sharp contrast to the soft double note of the Groove-billed." So for my part, that settled it that our bird was a Groove-billed ani. | The original documentation form event occurred in the afternoon

That evening when I returned from work I checked my Golden, Peterson, N.G.S. and Audubon Master Guide for their accounts of the Townsend's and similar species. I eliminated the following; Hermit Warbler - no cheek patch: Blackburnian - dosn't [sic] have a black throat: Black-throated Green - has solid back color and cheek patch not as bold, no black cap. Of the references mentioned, the N.G.S. has the most accurate illustration of the birds head but I can't verify that the bird I saw did or didn't have yellow under the eye. | The original documentation form event lasted from approximately 07:20:00/07:20:45.

The documentation by William and Rebecca Otto is the only one submitted and forms the basis of this record. | Elimination of similar species: [...] We eliminated the possibility of the gull being an immature Bonaparte's gull by the following criterion: 1. Leg color. The gulls legs and feet were entirely black. Bonaparte's gull have reddish legs. This was apparent at great distance on the immature Bonaparte's gulls present. 2. Primary feathers. The gull had black outer primaries and gray inner primaries. Immature Bonaparte's having some obvious white inner primaries.) 3. Behavior. Although this may seem rather unscientific, the gull not joining the groups of feeding or loafing gulls present seems significant to me. | The original documentation form event lasted around 30 minutes.

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.

The documentation form by Lilian Serbousek is the only one submitted and forms the basis of this record. | Elimination of similar species: [..] -seen with Water Pipits, Vesper Sparrow and Golden Plover and Horned Larks - looked quite similar to Vesper Sparrow-white outer tail feathers, buffy above and streaked, white below with streaks on breasts & sides (couldn't see bill well at this distance) [...] close enough to see bill was long and slender (like Vesper's pushed down and forward) also was pinkish and dark at tip (lower mandible was lightest) was sure it wasn't a Water Pipit because of streaked back, breast coloration and leg coloration - bird walked and ran, Savannah and Vesper Sparrow that were also on the ground hopped, flight was undulating and was more graceful compared to low buzzy flights of the two sparrows, the wings appeared pointed and long (as a whole the bird looked more slender) not as vocal as the Water Pipits, notes were higher and thinner (1 syllable instead of two) then Water Pipits
