Both of these species show gregarious flocking behavior except when nesting. This spunky little finch is the smallest member of the North American genus Carduelis. I caught this male pictured above harassing a female Ruby-crowned Kinglet as she was bathing in the water feature.

So, Maley suggests recognizing four species, instead of the two currently recognized. Maley has a forthcoming paper in The Condor ( Mitochondrial and Next-Generation Sequence Data Used To Infer Phylogenetic Relationships and Species Limits in the Clapper/King Rail Complex ) that should provide the published evidence needed for taxonomic bodies to act, or at least open the discussion. I should also note that the abstract for the Condor paper proposes five , not four, species. MORE

The obvious choice was the Mallard , that plucky familiar northern hemisphere species that is the father of the even more familiar domesticated duck.
