Western Wood-Pewee
|

|
Elm Lake, near Belmond, Wright County
|
The bird was found in a narrow grove of mature Cottonwood surrounding Elm Lake, the lake is in the mist of farmland with a small pasture on the north.
|
The documentation form by Joe Schaufenbuel is the only one submitted and forms the basis of this record. | Elimination of similar species: Eastern Phoebe is larger and wags its tail. Empidonaxes are smaller with shorter wings and tail. Confusion with the Eastern Pewee is certain if plumage is used. Subtle differences in plumage were noted in my observation of the Western Pewee, when compared to my experience with the Eastern Pewee. The throat appeared whiter and contrasted more with the breast and head than a Eastern, also, as mentioned before, the color of the upper-parts appeared more grayish and not as green. Since the call was heard at close range, and having seen the vocalizing bird as well as my familiarity with the Western Pewee's call I believe the identification totally on voice is a valid one. | The original documentation form event lasted from 12:00:00/12:12:00.

Great Egret: has yellow bill w/out black tip, & dark legs. Cattle Egret: has yellow to orange bill without black tip, has yellow to dark (not green legs) & is sociable, & wouldn't spend over a week in a marsh. Reddish egret: has a similar bill, but with base flesh-colored rather than gray. Has bluish, not green, legs, has a shaggy neck, and is unlikely to be found in Iowa. The white primaries eliminate other white large birds. The only thing left is immature Little Blue Heron.

The documentation form by Barbara L. Wilson is the only one submitted and forms the basis of this record. | Elimination of similar species: All the terns I've managed to identify at the Slough before have been Forsters. There was a Forsters at the slough that evening, in fact, with white primaries. It tried to land on a piling by the other two, but then left. The Commons differed from Forster's terns by having dark primaries (adult) and on eye patch that circled the back of the head (other bird).
