Townsend's Solitaire
|
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.

[...] I rule out Kestrel on basis already indicated above, as well as Sharp-shinned Hawk, since this bird had pointed wings and the breast striping was lengthwise on light background, rather than crosswise on reddish or rusty background.
