Domestic ducks and geese trace back to two species of waterfowl each: the mallard duck (Anas platyrhynchos) and the muscovy duck (Cairina moschata), the greylag goose (Anser anser) and the swan goose (Anser cygnoides). Ducks and geese were known in ancient China and Egypt, where they had already

A recent survey among wild birds demonstrated the presence of a unique genotype of avian bornavirus (ABV) in wild geese and swans in North America. Here, we report the first complete genome sequence of an avian bornavirus of the goose genotype.

species for avian influenza virus were identified: barnacle goose, bean goose, brent goose, pink-footed goose, bewick’s swan, common gull, and guillemot. Dabbling ducks were more frequently infected than other ducks and Anseriformes; this distinction was probably related to bird behavior rather than

not that of Popper (1968). Consider the certain demonstration that a particular swan is black (let us assume the bird is a bird and not a fish, it a swan and not a goose, or ugly duckling) by examining every feather (and assume a black swan is defined in terms of its feather colours). This is NOT “verification

The ability of modern jet engines to ingest birds and continue to operate is largely misunderstood or not contemplated at all in the aviation industry. Currently there is not one jet engine operating in the world that is certified to ingest one large bird (goose, swan, stork, pelican, vulture, etc

Abstract Along the east Atlantic migratory flyway, goose and swan species rely on the availability of suit-able coastal habitats as staging sites during migration and for breeding. Especially for the Russian part of the flyway, detailed descriptions of these habitats in relation to use

swan, greylag goose, common eider and the goosander, did not show obvious increases in breeding densities after mink removal. We conclude that feral mink may locally limit the breeding densities of some smaller waterfowl species and thus reduce the diversity of the waterfowl community in the outer

The embarrassment of riches: agricultural food subsidies, high goose numbers, and loss of Arctic wetlands — a continuing saga R.L. Jefferies, R.F. Rockwell, and K.F. Abraham Abstract: Agriculture has provided a nutritional subsidy to the Anatidae (swans, geese, ducks), which has affected
