![]() ![]() When hunting in timber or swampy area, a wood call is preferable. Most acrylic calls have the capability of getting much louder than double reed calls. Acrylic calls are preferred in large open spaces for a call to reach out and find the ducks. Different waterfowl hunters have varying opinions on what the best type of duck call is and when it is most effective. This is important for different types of duck hunting. The key difference between wood and acrylic duck calls is that acrylic calls are much louder and carry much further than wood duck calls. The two most common high quality duck call materials are wood and acrylic. There are many other variations and techniques to make effective sounds with a duck call. The more experienced callers simply push the air from their diaphragms with no words to be spoken into the call. With the improvement of calls and calling techniques the more experienced callers do not use their voice to perform their techniques. In order for a hunter to make the feeding call, the hunter must say a quick repetition of "tiki-tika" or "duga-duga". Hunters would use the air from their diaphragms into the call while saying "hut", "wuit", or "oak" to make the single quack. The insert is the end in which the sound is produced. Early duck calls were simple woodwind instruments with a barrel, a sound board and a cork that is used to hold the reed into place on the sound board, make up what is known as the insert. The goal of a duck call is to sound like a realistic live duck, in attempts to decoy, or fool a duck into believing the decoys that are seen by a duck, and the sound that is heard appears lifelike.Īs a tool, a duck call is like a traditional whistle made to emulate the sound of a duck. Today's duck calls usually fall into three main categories: single, double, or triple reed call with many variations, although the triple reed is rare. Early duck call tools were basic woodwind instruments, while later innovations are constructed of rubber and plastic, and allow the hunter to adjust the volume and tone of the calls with reeds. Canadian biologist and linguist Bruce Bagemihl prefers to call this sort of thing “biological exuberance,” and his 2000 book with that title makes for a fascinating read for those curious to learn more.A duck call may be either the sound- imitation process used in waterfowl hunting, by which a hunter lures waterfowl, or the actual tool which the person uses to do so. Necrophilic behavior has also been observed in ground squirrels, New Zealand sea lions, rock doves, pilot whales, and crows, among other animals. Levick was horrified to witness not just male penguins mating with other males but one young male Adelie penguin attempting to copulate with a dead female. A British naturalist named George Murray Levick traveled to Antarctica with the 1910-1913 Scott expedition and spent several months studying the breeding habits of a colony of Adelie penguins at Cape Adare. Nor is necrophilia limited to mallard ducks. Tennent, while diligently tracking Mazarine Blue butterflies in Morocco in 1987, spotted several males of the species mating with each other rather than with females of the species. Female koalas sometimes mount other females, while male Amazon river dolphins have been known to penetrate each other’s blowholes. Same-sex pairings have been recorded in some 450 different species, from flamingoes and bison to warthogs, beetles, and guppies. Two male mallard ducks copulating would not actually be that surprising. The ornithologist managed to snap some photos of this odd behavior before intervening and collecting the dead duck specimen–over the noisy objections of its living "mate." It was the first documented case of homosexual necrophilia in the species. ![]() After a couple of minutes, the living duck "mounted the corpse and started to copulate, with great force," Moeliker recalled, only stopping for a couple of short breaks. Things took an unusual turn when Moeliker spotted a second, living male mallard nearby, which began pecking at the back of the dead duck's head. In this case, the collision was from a drake mallard duck ( Anas platyrhynchos) lying dead on its belly in the sand. The wing's all-glass facade sometimes took on mirror-like qualities, so there was a regular supply of birds colliding with the glass. On June 5, 1995, a Dutch ornithologist named Kees Moeliker was working quietly in his office in the new wing of the Natural History Museum in Rotterdam, the Netherlands, when there was an unusually loud bang one floor below. ![]()
