Occurrence Remarks |
The documentation form with an attachment by Michael Newlon is the one that forms the basis of this record. Other documentation forms by Thomas H. Kent and two documentation forms for two separate sightings by Carl Bendorf. | Elimination of similar species: Build, pale wings + color pattern, feather pattern on back/coverts distinctive. [...] No other calidrine sandpiper likely to be found in Iowa combines the coloration, size, and proportions of the Knot. The only species that combine the overall grey coloration and the heavy straight bill are Sanderling, much smaller, and Willet, much larger and longer-legged, with blue-grey rather than black bill and legs. The other shorebirds that are remotely similar are the Tattlers, which have more slender bills and paler legs; basic-plumaged Surfbird, which has a shorter, thicker bill, yellow at base, pale legs, and less-distinct face-pattern (but similar pattern on coverts/ scapulars/tertials); Great knot, which is supposed to lack a distinct supercilium, have round black spots on chest and flanks, black upperparts, a longer, more slender bill. . |
