Johnson, Ann	Prairie Warbler	Greenfield Township	My Yard - small acreage in northern Warren County, IA	Mixed open woods and field edge with creek and many shrubs	The documentation form with an addendum by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Palm Warbler - no streaking on breast; chestnut cap not evident; streaking was black; breeding plumage unlikely on this date Pine Warbler - belly and undertail coverts bright yellow; wingbars not as distinct as the wing was not as dark nor the bars as white: streaking on the sides darker than a pine [...] Magnolia Warbler - Magnolia's body and wings too dark; adult eliminated because of no streaking on breast (only sides) and no black facial mask; immature does not have heavy enough streaking nor yellow extending up the face and around the eye far enough and the wingbars are too contrasting (black and white) Cape May Warbler - vibrant yellow undertail coverts would seem to by and large eliminate the Cape May, especially when combined with no streaking on the breast and belly; wing bars were two distinct pale yellowish markings, not white or blotched together Blackburnian Warbler - unstreaked back; no distinct cheek patch; no white wing bars on dark wings Blackpoll/Bay-breasted Warbler - unstreaked back; primary identification of fall blackpoll is white undertail coverts which eliminates this bird immediately. Also this complex normally has more distinct white wing bars on darker wings and the streaking on the sides is not the stark black on brilliant yellow but a more muted yellowish wash. \| The original documentation form event lasted from 18:45:00/18:45:00.

Includes a record review document with votes and a documentation form submitted to the committee. The original documentation reports the bird as a Black-shouldered Kite	Johnson, Ann	White-tailed Kite	Norwalk	My home in northern Warren County, Iowa	Agricultural area with some riparian edges	The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. \| Elimination of similar species: Size, shape and flight pattern initially eliminated buteos and accipiters. I seriously considered both Northern Harrier and Peregrine Falcon. Until the bird got close enough to see the underparts, Peregrine was the most likely candidate based on the straight trailing edge of the wing, although I have never seen a Peregrine glide so effortlessly with few wing strokes taken. The flight pattern and white head made me aware that this was probably a kite. Of the other possibilities for this bird, all were eliminated by the white tail with no markings. Only a Ferruginous Hawk would share this characteristic. The black carpal spots on white wing linings were somewhat reminiscent of an Osprey, but other patterns, size, and flight pattern are not consistent. Although Northern Harrier males look very white from below, their heads are dark not white, and only the outer primary tips are dark as opposed to this bird's entire primary area. The tundra race of the Peregrine Falcon would appear light colored on the head, but would also show more dark markings underneath than this bird had. Mississippi Kite looks fairly white headed at a distance, but the underparts and tail are gray. \| The original documentation form event lasted from 18:05:00/18:07:00.

Thelen, Ed	Western Tanager	Spirit Lake	My backyard birdbath - East edge of Spirit Lake	Suburban - edge of farmland	The documentation form by Ed Thelen is the only one submitted and forms the basis of this record. \| Elimination of similar species: Female oriole - size, shape and color of beak, length of tail and color of chin. Imm. Scarlet tanager - According to Master Guide to birding Vol 3 p. 196, juvenal [sic] Scarlet tanagers resemble the female but are more variable and have bright yellow wing bars. Also according to National Geographic Bird Guide it states that the immature scarlet tanager has faint wing bars. I don't think it was an immature scarlet tanager because this time of year the bird is not in juvenal [sic] plumage and the bird I saw had prominent and strong wing bars. Also the bird I saw had a very light colored rump and also its nape was a shade lighter than its back giving the birds upper part the light-dark light sequence for its nape-back-rump. This is a characteristic of the Western Tanager. This is what Bent (1958) p 472 has to say about the plumages of the 1st year male western tanager. "There is considerable variation among individuals, these one-year old males are as a whole somewhat less brilliant than the adults. The black of the upper part is duller and more or less intermixed with greenish. The red on the head paler, less intense and more restricted in area; and the yellows decidedly duller and less brilliant." \| The original documentation form event lasted from 19:15:00/19:18:00.
