The word "goose" is a direct descendant of Proto-Indo-European *ǵʰh₂éns.In Germanic languages, the root gave Old English gōs with the plural gēs and gandra (becoming Modern English goose, geese, gander, respectively), West Frisian goes, gies and guoske, Dutch: gans, ganzen, ganzerik, New High German Gans, Gänse, and Ganter, and Old Norse gās and gæslingr, whence English gosling.
The ducks, geese, and swans are small- to large-sized birds with a broad and elongated general body plan. [2] Diving species vary from this in being rounder. Extant species range in size from the cotton pygmy goose , at as little as 26.5 cm (10.5 in) and 164 g (5.8 oz), to the trumpeter swan , at as much as 183 cm (6 ft) and 17.2 kg (38 lb).
Anseriformes is an order of birds also known as waterfowl that comprises about 180 living species of birds in three families: Anhimidae (three species of screamers), Anseranatidae (the magpie goose), and Anatidae, the largest family, which includes over 170 species of waterfowl, among them the ducks, geese, and swans. Most modern species in the ...
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
The Chinese goose is more aggressive and noisy than other geese and can be used as a guard animal to warn of intruders. [37] The flesh of meat geese is dark-coloured and high in protein, but they deposit fat subcutaneously, although this fat contains mostly monounsaturated fatty acids. The birds are killed either around 10 or about 24 weeks.
The Chinese and African Geese are the domestic breeds of the swan goose (A. cygnoides); they can be recognized by their prominent bill knob. [ 1 ] Some breeds, like the Obroshin Goose and Steinbach Fighting Goose , originated in hybrids between these species (the hybrid males are usually fertile – see Haldane's Rule ).
The spur-winged goose (Plectropterus gambensis) is a large, Sub-Saharan African waterbird in the family Anatidae, which includes geese and shelducks.However, P. gambensis developed unique environmental adaptations, which resulted in the evolution of several anatomical features that are not shared with other anatids; thus, the species has been classified one step further into its own subfamily ...
Fowl are birds belonging to one of two biological orders, namely the gamefowl or landfowl (Galliformes) and the waterfowl (Anseriformes).Anatomical and molecular similarities suggest these two groups are close evolutionary relatives; together, they form the fowl clade which is scientifically known as Galloanserae or Galloanseres (initially termed Galloanseri) (Latin gallus ("rooster") + ānser ...
