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.
