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.

First-winter Iceland typically much paler, especially the uppersurface of the primaries which are paler than the rest of the mantle, and Iceland should show mottling in the tertials and tail band. I suppose I cannot exclude a heavily-pigmented 'Kumlien's' Gull or an Iceland-Thayer's intergrade as described in Kevin Zimmer's Birding article. Both species are apparently highly variable. | The original documentation form event lasted from 10:45:00/11:15:00.

[...] I picked this bird out because of it's small size compared to the other Herring Gulls present (40). It was smaller than any of the Herring gulls present, but still much larger than any of the numerous Ring-billed gulls. The head appeared more rounded than the Herring gulls and the heavy brown streaking on the nape and neck was more extensive and darker than any Herring present. The bill w/a red gonys mark on the lower mandible was shorter and thinner w/less gonys than the Herrings. They eye iris was dark not yellowish as in all the Herrings present. | The original documentation form event lasted from 10:00:00/10:35:00.

Pale Thayer's may be confused with same-aged Iceland Gull, but Iceland typically much paler than this individual. Iceland should also show pale, mottled tertials and tail which are concolor with the upperparts. This bird's tertials and tail were unpatterned (except at the edges of the tertials) and darker than the remainder of the upperparts. Iceland's folded primaries are paler than the remainder of the mantle, not darker as in this bird. Slaty-backed, Glaucous-winged, and Glaucous-winged X Western hybrid Gulls all larger, have more massive bills, less likely in Iowa. | The original documentation form event lasted from 10:15:00/10:40:00.

The documentation form by Bob Cecil is the only one submitted and forms the basis of this record. | Elimination of similar species: See above discussion. [...] The wingtip pattern is what caught my attention. There was much less darkening to the outer primaries than on accompanying gulls. [...] When viewed fro [sic] underneath, the wingtips of the subject bird were white to the tips, with the exception of very narrow black tips at the tips of the primaries. This was very different from the adult Herring/Ring-bills which had substantial black towards the end of the underwings. | The original documentation form event lasted from 10:30:00/10:45:00.
