Golden Eagle
|
Hawkeye Wildlife Management Area
|
1/2 mile south of Johnson Co. Rd. F-20, 4.9 mi. w. of the crossroad leading to the Dupont Bridge.
|
General: border between an extensive tract of riverbottom forest and a half-mile stretch of corn and soybean fields (with large patches of unharvested beans). At the north edge of the fields was a road, followed by a wooded ridge. Specific: Perched at the edge of a narrow screen of trees that extended out from the forest, between two fields. [drawing]
|
The documentation form by Michael Newlon is the only one submitted and forms the basis of this record. Other observers include Richard DeCoster. | Elimination of similar species: The three species with which confusion is most likely are the bald eagle (imm) and red-tailed and rough-legged hawks (dark-phase). Several points rule out these species. (1) Size: the body length of the bird was 2&1/2-3 times that of a crow that perched in the same tree; the two hawks are not nearly this large. (2) tail pattern: imm. bald eagles sometimes show tails that are darker at the tip than at the base, but all such individuals that I have seen have had a gradual transition from dark to light, rather than the sharp boundary that this bird showed. Adult melanistic redtails usually have red tails; imm birds should show dark tails crossed by darker bands. (3) Wing pattern: imm bald eagles have white in the wing, but this is usually in the wing-lining rather than the primaries and secondaries; dark-phase rough-legs usually have the primaries and secondaries entirely white. (4) build: bald eagle has longer neck, and more massive head and bill, than golden; this bird had the general proportions of a buteo. | The original documentation form event lasted from 09:00:00/09:30:00.

The documentation form by Mike Dooley is the only one submitted and forms the basis of this record. Other observers include Bill Scheible, John Havilcek, Joyce Havilcek, and Jim Durbin. | Elimination of similar species: None eliminated on-site. Possible mis-identifications, given the premium conditions and extended period under which this bird was studied, might be as follows (consulting the National Geographic Society field guide): (1) fall adult Blackburnian Warbler: bird in question was strongly streaked on breast and sides, not just flanks; (2) female Townsend's Warbler: streaking on breast and sides of bird in question did not have semi-necklace effect of Townsend's; olive of head and back much grayer; (3) female Praire [sic] Warbler: bird in question had extended yellow post-occular stripe; streaked breast, not just sides and streaks bolder; had white belly; (4) fall Blackpoll Warbler: bird in question was much more boldly streaked on breast and sides; had extended post-occular yellow stripe, clearly defined cheek patch. All of above eliminated due to bird in question having wings similar to back color and not of a contrasting charcoal, as well as having a bold yellow-olive rump. All but Praire [sic] Warbler eliminated due to bird in question's virtual lack of wing bars. | The original documentation form event lasted from 13:45:00/15:00:00.

The documentation form by Mike Thomas is the only one submitted and forms the basis of this record. Other observers include Ann Johnson. | Elimination of similar species: Lesser scaup (size, head shape, head color on male, whiter sides on male in direct comparison to lesser scaups. Side by side comparison with lesser scaup was thankfully easy. The male's rounded head contrasted clearly with the more pointed heads of the lesser scaup. Also, the dark green head of male was visible. The male birds sides were whiter than male lesser scaup's sides and the difference in size was noticeable. | The original documentation form event lasted from 15:45:00/16:15:00.
