East Lawn Cemetery
|
East Lawn cemetery, Sheldon (extreme western O'Brien Co.), Iowa. This cemetery covers an extensive area and is planted with many large evergreen, viz., spruce (mostly Norway Spruce), pine (Austrian Pine, I think), and a species of cedar or juniper (I am not sure of the species; it resembles the Red Cedar of the East somewhat, but has a more open crown); these junipers carry many blue berries.
|
among evergreen, moving from tree to tree, selecting mostly the juniper/cedar trees, see above: Location
|
The documentation form by John Van Dyk is the only one submitted and forms the basis of this record. | Elimination of similar species: one who knows neither the Solitaire not the Mockingbird might conceivably mistake it for the latter. But the Mockingbird is larger, has no eye ring, shows no buff on the wing, and flashes conspicuous white in wing and tail in flight. I have lived both in California and in southern New York, where the Mockingbird is common: I am very familiar with the Mockingbird. | The original documentation form event lasted from 14:15:00/14:45:00.

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.

The size and bill led me to an immediate identification. I was puzzled about the plumage. I expected to see a juvenile or basic-plumaged bird, but the distribution of dark coloration was that of alternate plumage. I assume that the red/black throat, lines of neck, and gray tones had faded to give one rather uniform color. The drab light may have contributed some to the failure to see color differences, but the last observation was relatively close and the texture of the feathers could be seen. | The original documentation form event lasted from 07:45:00-08:30:00 and 12:20:00-12:45:00.

Otherwise, the slender, upturned bill, the head posture, the contrast between the back and the neck, and the gray neck and white throat eliminated Pacific and Common Loons. | The original documentation form event lasted from 13:46:00/15:43:00.

The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. | Elimination of similar species: Common Loon eliminated by smaller size, head posture, shorter, upturned bill, speckling on back, more rounded forehead, and sharp contrast between throat and back of neck. Pacific Loon eliminated by bill shape, head posture, speckling on back, two-toned (not three-toned) neck pattern, lack of chinstrap (not definitive, but helpful), and crown color not including the eye (should include the eye on Pacific Loon). | The original documentation form event lasted from 15:26:00/15:50:00.
