two terms not interchangeable, and not the same Explanation: Def. swimming bird- (vertebrate zoology) Any bird belonging to the orders Charadriiformes and Pelacaniformes. http://www.answers.com/topic/swimming-bird http://encyclopedia2.thefreedictionary.com/swimming bird NOT the same as waterfowl and therefore not interchangeable - Any member of the family Anatidae, web-footed birds with a broad bill containing fine plates, or lamellae; usually stocky and often long-necked, including ducks, geese (see goose), and swans. Waterfowl feed by dabbling, diving, or grazing. http://www.answers.com/topic/waterfowl |

not interchangeable Explanation: There is more than one way to classify bird groups taxnomically. One school of thought is the Sibley-Ahlquist taxonomy: http://en.wikipedia.org/wiki/Sibley-Ahlquist_taxonomy_of_bir... They use 'waterfowl' as a taxonomic group: "The classification appears to be cladistic because it codifies many intermediate levels of taxa: the "trunk" of the family tree is the class Aves, which branches into subclasses, which branch into infraclasses, and then "parvclasses", superorders, orders, suborders, infraorders, "parvorders", superfamilies, families, subfamilies, tribes, subtribes and finally genera and species. In fact, the Sibley-Ahlquist taxonomy is merely a highly structured result of phenetic studies; no cladistic methods were used in producing it. Though the strong subdivision into taxonomic ranks suggests accuracy, the "parv"-ranks are simply considered[who?] unnecessary as of 15 years later for example. The resulting arrangement differs greatly from the more traditional approach used in the Clements taxonomy. More recently published phylogenetic reconstructions[which?] based on cladistic and maximum likelihood analyses of DNA sequences lend credence to some of the DNA-DNA hybridization-based taxonomy, e.g. the recognition of palaeognathous birds as monophyletic and sister to all others, and the recognition that fowl and waterfowl (Galloanserae, initially named "Galloanseri"[citation needed]) are one anothers' closest relatives and sister to the remainder of all birds, Neoaves." In rival taxonomies, 'waterfowl' is not used. Here a links with different taxonomy methodology that provides an overview of bird families that are associated with water: http://www.answers.com/topic/charadriiformes-1 http://en.wikipedia.org/wiki/Charadriiformes I would use "swimming" bird only as a clarification, and not to indicate a specific group. -------------------------------------------------- Note added at 52 mins (2010-01-07 21:01:43 GMT) -------------------------------------------------- So swimming bird is certainly not a scientific term, to answer your question. |
