Lorenz studied instinctive behavior in animals, especially in greylag geese and jackdaws. Working with geese, he investigated the principle of imprinting, the process by which some nidifugous birds (i.e. birds that leave their nest early) bond instinctively with the first moving object that they see within the first hours of hatching. Although ...
Lorenz also discovered a long-lasting effect of his studies, and that was a shift in the species' sexual imprinting as a result from imprinting upon a foster mother of a second species. For certain species, when raised by a second one, they develop and retain imprinted preferences and approach the second species they were raised by rather than ...
Other examples are the classic studies by Tinbergen on the egg-retrieval behaviour and the effects of a "supernormal stimulus" on the behaviour of graylag geese. [17] [18] One investigation of this kind was the study of the waggle dance ("dance language") in bee communication by Karl von Frisch. [15]
In the late 1980s, Lishman approached Bill Carrick, a naturalist who was working on imprinting on the behaviour of geese. Carrick provided goslings, who Bill and his children worked with daily, eventually doing twice-daily runs on a motorcycle with the geese flying with him, then switching to the ultra-light. [2]
The Anserinae are a subfamily in the waterfowl family Anatidae.It includes the swans and the true geese.Under alternative systematical concepts (see e.g., Terres & NAS, 1991), it is split into two subfamilies, the Anserinae contain the geese and the ducks, while the Cygninae contain the swans.
Galliformes / ˌ ɡ æ l ɪ ˈ f ɔːr m iː z / is an order of heavy-bodied ground-feeding birds that includes turkeys, chickens, quail, and other landfowl.Gallinaceous birds, as they are called, are important in their ecosystems as seed dispersers and predators, and are often reared by humans for their meat and eggs, or hunted as game birds.
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 gás and gæslingr, whence English gosling.
A cladistic study of the morphology of waterfowl found that the magpie goose was an early and distinctive offshoot, diverging after screamers and before all other ducks, geese and swans. [ 2 ] This family is quite old, a living fossil , having apparently diverged before the Cretaceous–Paleogene extinction event – the relative Vegavis iaai ...
