|
large, wide riverbottom marsh with scattered woods.
|
The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. | Elimination of similar species: According to Eckert, the upper wing patches are diagnostic if the location is right. He gives the following example as an acceptable documentation: 'On the upper surface of each wing there was a rectangular or oval white patch on the flight feathers. This patch was on the inner primaries, and perhaps faded a bit into the secondaries and outer primaries.' This description fits the bird I saw. Eckert gives two other diagnostic marks that I did not see (feathered legs, rufous back and shoulders), but only one of these three marks is needed. The white tail is not diagnostic, but coupled with the light underparts and generally dark upper wing surface, tends to exclude Krider's and Harlan's Hawks which would have light upper wings and dark underparts, respectively. An ordinary Red-tailed Hawk would not ordinarily have an all white-tail nor such prominent upper wing patches. The raised wings in flight in the absence of wind favor Ferruginous Hawk over Red-tailed and Rough-legged Hawks. Rough-legged Hawk is excluded by the lack of prominent black and white pattern to body, wing and tail. | The original documentation form event lasted from 14:45:00/14:57:00.

Also has relatively plain wing with gray coverts and pale gray remiges. Canvasback (Aythya valisineria) of either sex safely separable on the basis of head and bill in profile. Again, male's head is dark brick-red, back and sides whitish, lacks bold wing pattern. Female mergansers easily separable on the basis of bill alone. | The original documentation form event occurred around 11:00:00.

Little Gull eliminated by its smaller size, dark bill, lack of any black color on the upperwing, and uniformly dark underside to the flight feathers. Ross' Gull eliminated by tail shape, bill size and color, and darker underwing.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Another observer was Susan B. Grove. | Elimination of similar species: The short body, longer neck, and bright orange bill color eliminates all species of loons. The only other similar species is Western Grebe, which has a dulller yellowish bill and dark lores and dark color around the eyes. | The original documentation form event lasted from 08:25:00/08:55:00.

The documentation form by Randy Pinkston is the earliest and the one that forms the basis of this record. Another documentation form by Stephen J. Dinsmore was submitted later. Another observer includes Susan Grove. | Elimination of similar species: I am uncomfortable committing to California Gull given the brief and distant view I had, and my limited past experience with the species. My fear is that this was just a small Herring Gull. Herring can be quite variable in overall size, bill size, and in terms of color and shade of the first-winter plumage. Supposedly 10-15% of first-winter Herrings' can have a "dipped-in-ink" bill in the fall (Harrison 1983 or Grant 1986?). | The original documentation form event lasted from 12:30:00/15:30:00.

The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Sinclair, Thomas H. Kent, and Jim Fuller were submitted later. | Elimination of similar species: Ring-billed and Herring gulls are the two most likely species of confusion. Ring-billed Gull never shows this much brown in any plumage, has a dark tail band in immature plumages, has a different wing pattern, and is structurally different from California Gull. Herring Gull is more similar in first-basic plumage, but always shows a pale window on the inner primaries, lacks the double dark bar effect in the innerwing, is larger, and very rarely shows a strongly bicolored bill. | The original documentation form event lasted from 10:55:00/12:24:00.
