| 1 | 88:91 | 2016-02-15 | 2016-02-16 | Rum River Dam, Anoka | Anoka | (record #2016-005, vote 10-0, origin vote 10-0). Adult male, photographed. First state record. The Committee also voted to accept the bird as wild. There are two genetically distinct and phenotypically identifiable subspecies of Mottled Duck: the Florida subspecies, A. f. fulvigula, occurring primarily in Florida, and the Western Gulf Coast subspecies, A. f. maculosa, which ranges from Alabama to south Texas and northeast Mexico. The bird was scrupulously researched and independently described by five observers. In addition, the Committee consulted an outside expert to further evaluate the question of hybridization. After discussion and deliberation, the Committee unanimously agreed that the bird was a Mottled Duck of the subspecies maculosa. While there was some discussion of the remote possibility of Mallard hybridization, the Committee determined that the bird had virtually none of the various plumage characteristics normally associated with a mixed species pairing. Given the range of plumage differences among members of this subspecies, the Committee agreed that the bird was within the normal scope of individual variation for maculosa. | Accepted | ||

| 94:115 | 2022-08-21 | Pelican Lake WMA | Wright | (record #2022-078, vote 0-7). The Committee unanimously agreed the documentation of this species requires great attention to details to successfully eliminate other similar duck species. The same level of attention would also apply to the elimination of Mottled Duck hybrids. Unfortunately, sufficient details which would aid the identification of the species were lacking. Examples might include elaborate details of the tail, the presence or lack of a white border of the speculum, and the presence of a black spot on the gape. | Not Accepted | ||||
