Yellow Rail
|
|
3 miles South of Emerson, Mills County, Iowa
|
In foxtail stubble in government set aside acres. The grass had been clipped about knee high + the machinery passing through had smashed much of it, leaving rows of standing stubble, some leaning into it, + flat rows. Dave said the bird was hard to see in it. This was next to end rows planted to a sparse stand of alfalfa, halfway to Knee high.
|
The documentation form based upon notes and observations by Dave McGrew is the only one submitted and forms the basis of this record. The documentation form was written by Barb L. Wilson. | Elimination of similar species: Upland Sandpiper (which he had seen in the same field same day), quail, partridge. I showed Dave rail pictures in Peterson's Eastern guide + the Audubon Master guide. He didn't think much of the yellow rail picture objecting particularly to the white feather edging on the back, + the dull color of legs + bill (which may vary seasonally). After looking through the book he felt rails were the best match, though the bill was a bit too acute but the tail matched. He felt some other species in the Yellow Rail/juvenile Sora area might be it. Except of course there is no other rail like that, at least here. | The original documentation form event occurred at 19:30:00.

The documentation form by Alan Grenon is the only one submitted and forms the basis of this record. Other observers include Babs Padelford, Loren Padelford, Ruth Green, Betty Grenon, and Bruce Wetteroth. | Elimination of similar species: This duck was similar in size or slightly larger than nearby Lesser Scaup; most of the bird was a brown slightly lighter than female Lesser Scaup, and without mottling patters. Among ducks that have considerable white on the face, few have white around the eye and extending back to the nape. This eliminates the scoters (also, the bill did not seem large or deep enough for most scoters), Harlequin Duck, Bufflehead, goldeneyes, Smew, scaup, and Northern Pintail (which might have a similar plumage, but with white lower on the neck and side of neck, patterning on the body, speculum, and more differences). Unmarked bill and wing eliminate aberrant Ring-necked Duck and scaup, respectively, and also other divers with contrasting wing markings (including Bufflehead, goldeneyes). The possibility of an aberrant Harlequin Duck exists, but that seems less likely than a young Long-tailed Duck at this location. | The original documentation form event lasted from 10:15:00/11:15:00 and 17:00:00/18:15:00.

The documentation form by Andrew S. Fix is the only one submitted and forms the basis of this record. Other observers include Craig Harms. | Elimination of similar species: By general shape, bill characteristic, and color this bird was identified as a scoter. The white/creamish spot between the cere and eye and lack of pale cheeks and throat ruled out the Black Scoter; the bill was Also too extended up the forward part of head for a Black Scoter. I did not feel comfortable differentiating Surf from White-winged based on the morphology of the head. No white wing patch was evident while this bird was on the water. In my experience (see #14), the white patches on the heads of female and immature scoters are very unreliable and highly variable. Fortunately the two key characteristics were plainly visible when the bird flew; paddling along the water for a short distance (confirmed scoter), and prominent white secondaries (confirmed white-winger scoter) | The original documentation form event lasted from 14:00:00/14:15:00.

The song is unmistakable and we watched this bird sing. While watching the bird we remarked on how it had overshot suitable habitat across the road and that is exactly where Jim Sinclair found this bird the following day. As we watched it forage in the treetops, it was constantly moving to the south and toward better habitat for this species. | The original documentation form event lasted from approximately 14:30:00/14:40:00.

The head was also a bit flatter and it rode higher in the water, just giving a different posture than a loon. Plumage details did not fit any loon. Western Grebe- Thicker neck, some color on neck and white cheek eliminated this one Pied-billed Grebe - Size, bill shape, and other features wrong. Horned/Eared Grebes - Although it gave much the same appearance as a horned grebe, size and bill eliminated both. | The original documentation form event lasted from 16:34:00/16:42:00.

Cormorants were eliminated because of straight posture, lack of throat patch, and basic plumage configurations. The bird was obviously larger than a Pied-billed Grebe which would, in addition to the yellow bill, eliminate all but Western Grebe.

The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. Other observers include Bery Engebretsen, Eugene Armstrong, and Eloise Armstrong. | Elimination of similar species: The long, thin neck eliminated ducks and loons and convinced me that the shape of the bird was most certainly a grebe. Western/Clark's shows white rather than gray on the chin, neck, and breast and is larger. Horned Grebes are smaller and also are white on the underparts. Pied-billed could be eliminated by the size and shape of the bill alone. Although fall Eared Grebes are fairly gray, the size equaling Hooded Mergansers and the large bill allowed me to eliminate that species. | The original documentation form event lasted from 16:30:00/16:40:00.
