Mallard-like ducks in the Playa Lakes Region
Fedynich, A.M. and O.E. Rhodes Jr.
The relationship of the Mallard (Anas plaiyrhynchos L.) to similar members of
the genus Anas is often complex (Johnsgard 1961). Hybridization of Mallards with
American Black Ducks (A. rubripes Brewster), Mottled Ducks (A. fulvigula
maculosa S.), and Mexican Ducks (A. diazi R.), further complicates taxonomic
status and identification of subgroups within the Mallard complex. Experimental
crosses and back crosses of Anatini result in a broad range of overlapping
phenotypes (Phillips 1915, 1921). Furthermore, subgroups within the Mallard
complex are often difficult to differentiate using biochemical methods (Ankney et
al. 1986, Hitchmough et al. 1990). Thus, for wild monomorphic hybrids within the
Mallard complex, it may be difficult at best to determine the taxonomic status of
both parental types based on plumage characteristics or biochemical analysis and
nearly impossible to determine in which Fi generation the bird belongs.
