Portrait Of A Hybrid Of American Black Duck And Mallard Royalty-Free Stock Image

Portrait of a swimming hybrid of american black duck and mallard. It is a large duck, nearly identical to Mallard in size and shape but with a much darker chocolate-colored body. Bill is yellow with a slight greenish tinge on males, dull grayish-green on females. Note blue wing patch lacks any white borders. Fairly common in northeastern North America, especially along the coast. Large flocks can gather in the winter in saltmarshes and estuaries, but also occurs in smaller numbers on ponds and lakes, often mixed with other duck species. Frequently hybridizes with Mallard.
