Rare bird documentation form for Golden Eagle near Waukon, 1978	Field notes	Birds--Identification Ornithology Rare birds	1978-03-26	1978-03-27	Rare birds documentation form	Rare bird documentation form for a Golden Eagle near Waukon in Allamakee County, IA on March 26, 1978.	Schaufenbuel, Joseph P.	Golden Eagle	Waukon	Ten miles North of Waukon, on Highway 76, Allamakee County, Iowa	The general area under the soaring bird was a bluff, covered mostly with Oak, Maple, Birch and scattered Junipers.

The documentation form by Joe Schaufenbuel is the only one submitted and forms the basis of this record. Other observers include Alan Branhagen. \| Elimination of similar species: Bald Eagle; my bird was not mottled as an immature Bald is, also my bird had totally dark under wing coverts. The distinct demarcation of light to dark on my bird also was rather un-Baldlike. Since an on the spot size comparison was made with a buteo, and the latter was found to be much smaller, I feel safe to say all others of this genus can be rolled out. \| The original documentation form event lasted from 08:15:00/08:25:00.

Rare bird documentation form for Golden Eagle at the Dupont Bridge in Hawkeye Wildlife Management Area, 1978	Field notes	Birds--Identification Ornithology Rare birds	1978-02-19	N/A	Rare birds documentation form	Rare bird documentation form for a Golden Eagle at the Dupont Bridge in the Hawkeye Wildlife Management Area in Johnson County, IA on February 19, 1978.	Newlon, Michael C.	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.
