Butterflying pork loin. Butterflying is a way of preparing meat, fish, or poultry for cooking by cutting it almost in two, but leaving the two parts connected; it is then often boned and flattened. [ 1 ]Spatchcocking is a specific method for butterflying poultry that involves removing the backbone, and spatchcock as a noun may refer to a bird ...
A wing-clipped Meyer's parrot perching on a drawer handle. While clipping is endorsed by some avian veterinarians, others oppose it. [7]By restricting flight, wing clipping may help prevent indoor birds from risking injury from ceiling fans or flying into large windows, but no evidence shows that clipped birds are safer than full-winged ones, only that clipped birds are subject to different ...
There is an intricate link between various fishing techniques and knowledge about the fish and their behaviour including migration, foraging and habitat. The effective use of fishing techniques often depends on this additional knowledge. [1] Which techniques are appropriate is dictated mainly by the target species and by its habitat. [2]
Gliding flight is heavier-than-air flight without the use of thrust; the term volplaning also refers to this mode of flight in animals. [1] It is employed by gliding animals and by aircraft such as gliders. This mode of flight involves flying a significant distance horizontally compared to its descent and therefore can be distinguished from a ...
Fish migrations involve movements of schools of fish on a scale and duration larger than those arising during normal daily activities. [1] Some particular types of migration are anadromous, in which adult fish live in the sea and migrate into fresh water to spawn; and catadromous, in which adult fish live in fresh water and migrate into salt ...
Bird trapping techniques to capture wild birds include a wide range of techniques that have their origins in the hunting of birds for food. While hunting for food does not require birds to be caught alive, some trapping techniques capture birds without harming them and are of use in ornithology research.
A gannet begins its takeoff run: Much "fuel" is needed for this huge bird to achieve take-off. Sprats and other forage fish that are abundant in the summer can provide this. In the Baltic Sea, cod, herring, and sprat are considered the most important species. [25] Cod is the top predator, while the herring and sprat primarily are recognized as ...
Boids. Boids is an artificial life program, developed by Craig Reynolds in 1986, which simulates the flocking behaviour of birds, and related group motion. His paper on this topic was published in 1987 in the proceedings of the ACM SIGGRAPH conference. [1] The name "boid" corresponds to a shortened version of "bird-oid object", which refers to ...
