Occurrence Remarks |
The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. | Elimination of similar species: The bill and body proportions were those of a Dunlin, but the date and plumage were new for me. The streaks on the underparts, worn edging on some wing feathers, and eye line appear to be retained alternate features, while the lack of black on belly and rufous in wing are features of basic plumage. I assume that this was an adult partially molted to basic plumage. Although Dunlin is usually a late fall migrant, both Iowa and Minnesota have a few July records. According to Prater et al. (1977), nearctic birds molt before migrating; therefore, a bird in mostly basic plumage would not be unusual. White-rumped Sandpiper is exclude [sic] by the tail pattern, body proportions and bill length. Baird's Sandpiper has a shorter bill, longer tail/wing extension, slimmer profile, and browner and scaly upperparts. | The original documentation form event lasted from 14:00:00/14:45:00 approximately. |
