The documentation form by Randall Pinkston is the only one submitted and forms the basis of this record. | Elimination of similar species: Contrasted with first-winter Herring Gull above. First-winter Iceland typically much paler, especially the uppersurface of the primaries which are paler than the rest of the mantle, and Iceland should show mottling in the tertials and tail band. I suppose I cannot exclude a heavily-pigmented 'Kumlien's' Gull or an Iceland-Thayer's intergrade as described in Kevin Zimmer's Birding article. Both species are apparently highly variable. | The original documentation form event lasted from 10:45:00/11:15:00.

Really there was nothing else it could be. I considered an immature Palm Warbler but by late April the diagnostic marks should be apparent. The lack of a superciliary line and brownish cap, coupled with feeding behavior higher in the canopy and lack of tail-wagging, rule out Palm Warbler. Extensive white in the outer rectrix supports Pine Warbler.

Pale Thayer's may be confused with same-aged Iceland Gull, but Iceland typically much paler than this individual. Iceland should also show pale, mottled tertials and tail which are concolor with the upperparts. This bird's tertials and tail were unpatterned (except at the edges of the tertials) and darker than the remainder of the upperparts. Iceland's folded primaries are paler than the remainder of the mantle, not darker as in this bird. Slaty-backed, Glaucous-winged, and Glaucous-winged X Western hybrid Gulls all larger, have more massive bills, less likely in Iowa. | The original documentation form event lasted from 10:15:00/10:40:00.
