Hi Everyone,
The 2018 ebird checklist went live today, as did the Clements checklist. Here is the change comment. The monotypic group Mallard (Mexican) Anas platyrhynchos diazi is elevated to species rank as Mexican Duck Anas diazi. Genetic divergence of Mexican Duck from Mallard is at comparable levels to other taxa that are recognized as species, such as American Black Duck Anas rubripes and Mottled Duck Anas fulvigula (McCracken et al. 2001, Lavretsky et al. 2014a, 2014b, 2015); and hybridization between Mallard and Mexican Duck has not been demonstrated to occur at higher levels than between Mallard and other species in the Mallard complex. Revise the range description for Mexican Duck from "S Texas, New Mexico and Arizona south to central Mexico" to "southeastern Arizona, southern New Mexico, and western Texas (Trans-Pecos region) south to central Mexico".

E-bird seems to think so, so I was wondering, if anyone knows for sure, it is all confusing to me. If it has, then this will be a new species for Colorado, since there have been more and more Mexican Ducks in the state, in the last several years. >From e-bird's Home Page: If eBird had a subspecies group such as Mallard >(Mexican) that was relevant to the new split, then those entries will be >upgraded from a subspecies group to the new species (e.g., Mexican Duck). If >you did not specify the subspecies, then we try to assign records based on >known range and occurrence patterns. -- Brandon Percival Pueblo West, CO -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.
