Ducklike

Ducklike is a descriptive term used to indicate resemblance to ducks, typically in physical form or behavior, without implying taxonomic relation. In zoological descriptions, a species or specimen may be called ducklike if it exhibits features commonly associated with ducks, such as a broad, flattened bill, a compact body, a short neck, and webbed feet, as well as an affinity for aquatic habitats. The term can apply to living species that are not true ducks, including other waterfowl with convergent traits, or to fossil or extinct taxa whose morphology resembles that of ducks but falls outside the crown group Anatidae. Ducklike traits may also describe behavior, such as dabbling at the water surface, swimming with a buoyant, low-slung body, or aggregating near wetlands.

In scientific contexts, ducklike configurations are often discussed as examples of convergent evolution toward aquatic foraging and herbivory. The use of ducklike is necessarily informal and descriptive rather than taxonomic, and it should be understood as a comparative shorthand rather than an assertion of close kinship. The term can help convey functional or morphological similarities across birds and beyond, but it is dependent on the observer’s perspective and the features emphasized.
