A snare is tied near the base of a bird's throat, which allows the bird only to swallow small fish. When the bird tries to swallow a large fish, the fish is caught in the it's throat and when it returns to the fisherman's raft, he helps the bird to remove the fish.Historically in China, Japan and Macedonia, the fishing skills of which bird have been put to good use this way?
"in its throat. The birds are prevented from swallowing the fish because of a ring tied around their necks. The cormorants, however, are still able to swallow smaller fish. Though the ropes are strong, the fishing masters are able to quickly break them if a bird’s rope gets caught beneath rocks, ensuring the bird will not drown. Each night, cormorant fishing officially begins when three fireworks are set off in the evening sky. At first, the boats come down the river, one by one, catching fish. They use a fire attached to the front of the boat to attract the"

It has been estimated that an adult bird needs to eat about forty of these per day—sand eels, herring, sprats and capelin being the most often consumed. It fishes by sight and can swallow small fish while submerged, but larger specimens are brought to the surface. It can catch several small fish in one dive, holding the first ones in place in its beak with its muscular, grooved tongue while it catches others. The two mandibles are hinged in such a"
"Cormorant fishing Cormorant fishing is a traditional fishing method in which fishermen use trained cormorants to fish in rivers. Historically, cormorant fishing has taken place in Japan, China and Korea, as well as Greece, Macedonia, and, briefly, England and France. It is described as a method used by the ancient Japanese in the ""Book of Sui"", the official history of the Sui Dynasty of China, completed in 636 AD. This technique has also been used in other countries but is currently under threat in China. To control the birds, the fishermen tie a snare near the base of the bird's"
"close relatives of cormorants, are also used for this fishing technique on occasion. In Guilin, China, cormorant birds are famous for fishing on the shallow Lijiang River. Cormorant fishing is an old tradition in Greece and Macedonia, especially on Doiran Lake which lies in the border of the two countries, and it is still practiced today by some traditional fishermen. In Western Europe, cormorant fishing took place briefly from the 16th to 17th centuries, primarily in England and France. Though the fishing method is similar to those used in Japan and China, the European method was developed independently and was"
"elsewhere around the globe. In it, fishermen tie a line around the throats of cormorants, tight enough to prevent swallowing, and deploy them from small boats. The cormorants catch fish without being able to fully swallow them, and the fishermen are able to retrieve the fish simply by forcing open the cormorants' mouths, apparently engaging the regurgitation reflex. In Norway, cormorant is a traditional game bird. Each year c. 10,000 cormorants are shot to be eaten. In North Norway, cormorants are traditionally seen as semi-sacred. It is regarded as good luck to have cormorants gather near your village or settlement."

Large fish are caught with the bill-tip, then tossed up in the air to be caught and slid into the gullet head-first. A gull will sometimes stand on the pelican's head, peck it to distraction, and grab a fish from the open bill. Pelicans in their turn sometimes snatch prey from other waterbirds. The brown pelican usually plunge-dives head-first for its prey, from a height as great as , especially for"
"to six round, white eggs are placed on a litter of fish bones and disgorged pellets. The bird has regular perches or stands from which it fishes. These are usually low over the water. It sits upright, its tail pointed downwards. It drops suddenly with a splash and usually returns at once with a struggling captive. Large food items are beaten on a bough or rail; small fish and insects are promptly swallowed. A fish is usually lifted and carried by its middle, but its position is changed, sometimes by tossing it into the air, before it is swallowed head"

It appears that the young bird is taking lessons from an older bird that's teaching him bird things. The older bird is teaching the young one how to fly by flapping wings. The young bird takes off from a branch, only to drop after only a few seconds. Pooch then helps out by taking feathers from a turkey, and offers them to the young bird. The young bird is able to fly"
"bird that ventures within reach of their long neck and bill. The Oriental darter (""A. melanogaster sensu stricto"") is a Near Threatened species. Habitat destruction along with other human interferences (such as egg collection and pesticide overuse) are the main reasons for declining darter populations. Darters feed mainly on mid-sized fish; far more rarely, they eat other aquatic vertebrates and large invertebrates of comparable size. These birds are foot-propelled divers which quietly stalk and ambush their prey; then they use their sharply pointed bill to impale the food animal. They do not dive deep but make use of their low"

Some caution should be used in keeping the bird's beak away from the handler's face, as is the case with any bird. (). Raptors are adapted carnivores. Their talons and beaks are designed to rend flesh from prey. They can cause serious injury to an unwary handler! Use of heavy leather gloves is recommended when handling raptors. Though a raptor's beak and talons can pierce it, it will provide some"

Black caracara mostly fish in areas of fast moving rivers where migratory fish are forced to bottleneck and become trapped among plants or within shallow pools, reflecting their opportunistic nature. This species can also be identified from other species by their harsh, piercing, single note ""kraaaa"" calls that usually occur during flight. This call is usually repeated several times, often ending in a decrescendo. They do not exhibit diverse vocalizations,"

"birds and mammals. The snake uses its sharp rearward-pointing teeth to seize its prey, then wraps its body around the prey, at the same time contracting its muscles, killing the prey by constriction. It is often found near human habitation due to the presence of rats, mice, and other vermin as a food source. However, its equal affinity for domesticated birds and mammals means it is often treated as a pest. In captivity, its diet consists primarily of commercially available, appropriately sized rats, graduating to larger prey such as rabbits and poultry as it grows. Exceptionally large pythons may even"
"slowly low over the water with legs dangling and head looking down, then dipping feet down and hovering momentarily when prey is sighted. The prey is then snatched with the bill and swallowed in flight. This method of hunting can be very successful, with one birds catching prey on 27 of 33 attempts during one 45-minute session. It is also opportunistic, and feeds on swarming termites when they conduct their nuptial flights, snatching as many as 47 alates (flying termites) in five minutes. This species has been recorded foraging for insects flushed by grazing cattle and buffalo, in a manner"
"otters). Another method is to remove the shell from the prey. Molluscs are attached to their shell by strong muscular ligaments, making the shell's removal difficult. Molluscivorous birds, such as oystercatchers and the Everglades snail kite, insert their elongate beak into the shell to sever these attachment ligaments, facilitating removal of the prey. The carnivorous terrestrial pulmonate snail known as the ""decollate snail"" (""decollate"" being a synonym for ""decapitate"") uses a similar method: it reaches into the opening of the prey's shell and bites through the muscles in the prey's neck, whereupon it immediately begins devouring the fleshy parts of"

When he captured a fish, he would cut it open with a knife he fashioned out of a biscuit tin and dry it on a hemp line over the raft. Once, a large storm hit and spoiled his fish and fouled his water. Poon, barely alive, caught a bird and drank its blood to survive. When he saw sharks, he refrained from swimming and sought to catch one, using the remnants of caught birds as"

This short amount of time per bout is achieved by this finch's drinking method. It swallows the water it gets while its bill tip is still submerged, unlike most birds that bring their bill tip up to swallow. This unique action is accomplished by having the tongue scoop water into the pharynx. Then, the front of the larynx forces the water into the oesophagus, which, through peristalsis, takes the fluid to the crop. This"

Subsequent studies have dismissed this idea and the rough edge of the bill has been suggested as being an adaptation to help handle hard and slippery shells. They forage for prey by holding their bill tips slightly apart and make rapid vertical jabs in shallow water often with the head and neck partially submerged. The gap in the bill is not used for handling snail shells and forms only with age. Young birds that lack a gap are still able to forage on snails. It has been suggested that the gap allows"
"in large concentration when seasonal conditions require it, these species can be hunted with relative ease. Waterfowl are typically hunted using the “contour flight with short glide attack” technique, in order to surprise the prey before it can take flight or dive. In one case, a golden eagle was able to capture a mallard as it took off in flight. Other water birds are generally less frequent prey but may become regular in the diet in marsh-like northern regions and coastal areas. Scotland, being surrounded by coasts and possessing quite a wet climate, often hosts water birds which become prey"
"species is widespread and common, occurring far inland in some regions. Small crabs are the favoured food in coastal regions but a wide variety of other animals are eaten including insects, worms, snails, shrimps, frogs, lizards, small fish and sometimes other small birds as well. The bird perches almost motionless for long periods waiting for prey. When it spots something it glides down to catch it and then flies back to the perch where larger items are pounded against the branch to subdue them. Any indigestible remains are regurgitated as pellets. The nest is a hole, either a natural tree"
"and enormous, molar-like teeth allowed them to prey on molluscs and brachiopods by plucking their prey off of the substrate, and crushing the shells. Among birds, the eponymous shorebirds known as oystercatchers are renowned for feeding upon bivalves. At least one bird of prey is also primarily a molluscivore—the snail kite, ""Rostrhamus sociabilis"". The limpkin is a small rail-like bird that feeds almost entirely on apple snails. Other birds that will eat molluscs occasionally include mergansers, ducks, coots, dippers and spoonbills. Cone snails: Some cone snails hunt and eat other kinds of snails, such as cowries, olive shells, turbo snails,"

When feeding, morays launch these jaws into the mouth cavity, where they grasp prey and transport it into the throat. Moray eels are the only known animals that use pharyngeal jaws to actively capture and restrain prey in this way.In addition to the presence of pharyngeal jaws, morays' mouth openings extend far back into the head, compared to fishes which feed using suction. In the action of lunging at prey and biting down, water"

If startled it may crouch to avoid detection, or may run away, but seldom flies unless danger is very close. Even then, it flies with rapid wingbeats for only a short distance. It forages by scratching in the plant litter like a chicken, leaving distinctive circular depressions. It mainly feeds on invertebrates and has a particular liking for termite larvae. One individual was found to have eaten snails, cockroaches, beetles, flies, bugs and caterpillars. It may"

In Africa, often the commonest cichlids, including many species in the ""Haplochromis"" and ""Tilapia"" genera, seem to be preferred. The pelican's pouch serves simply as a scoop. As the pelican pushes its bill underwater, the lower bill bows out, creating a large pouch which fills with water and fish. As it lifts its head, the pouch contracts, forcing out the water but retaining the fish. A group of 6 to 8 great white pelicans gather in a horseshoe formation in water to"

Because cormorant fishing is part of the Imperial Household, the Nagara River has become a protected river, which keeps it clean and healthy, allowing cormorant fishing to continue through the ages. The birds have become such a part of Japanese lore, that they have given rise to the expression ""unomi"" (鵜呑み), which means to “swallow whole like a cormorant” or “accept without questions,” because they can swallow fish whole without choking on the scales.

About 60% of dives are to the benthic zone and about 10% are to the pelagic zone, with the rest of the dives being to zones in between the two. Many fishermen see in the great cormorant a competitor for fish. Because of this, it was hunted nearly to extinction in the past. Thanks to conservation efforts, its numbers increased. At the moment, there are about 1.2 million birds in Europe (based on"

They may also dig for bottom-dwelling invertebrates, and the smooth-fronted caiman will even hunt on land. Some crocodilian species have been observed to use sticks and branches to lure nest-building birds. Nile crocodiles are known to hunt cooperatively, and several individuals may feed on the same carcass. Most species will eat anything suitable that comes within reach and are also opportunistic scavengers. Crocodilians are unable to chew and need to swallow food whole, so prey that is too large to swallow"

Aquatic prey is obtained by diving or by swimming on surface with the head submerged, and terrestrial insects and their larvae are picked off vegetation. A line slanting downward from the eye to the tip of the opened lower mandible may be used for sighting on prey before diving or when swimming under water. The grebe probably opens its bill and looks down the eye-line toward its target. European breeders, which have to compete with the larger great crested grebe for fish,"

Izaak Walton's 1653 book describes otter pups, three to four months old, being domesticated and trained. The otters were muzzled to prevent them eating fish and secured by lines to their master. The otters then chased fish in a pond into a net. Another technique was to submerge nets and get the otters to shepherd the fish into them, after which the nets, along with otters and catch, were retrieved. In ancient China, the otter wore a"

If the angler intends to release a fish, it is advisable use pliers to flatten the barbs on the lure's hooks. Chain pickerel can swallow an entire lure, so it will be much easier to free a deeply hooked fish and get it back into the water as soon as possible. Practically any bass lure can be effective for pickerel, although like most pike, they seem to be particularly susceptible to flashy lures which imitate small forage"

Occasionally, they may capture other birds on the wing, including nocturnal migrants, taking advantage of their distraction and diminished visual acuity to intercept them in mid-flight. They seem to hunt mostly by opportunity, taking whatever detectable prey item that is available, preferably those that are active. Most prey, even up to the size of small rabbits, are swallowed whole. While a small rodent can easily be swallowed in an instant, if the prey item is large, the swallowing process can appear grueling and grotesque and in"
"Prey fish are typically swallowed whole and not cut into small pieces with the saw, although on occasion one may be split in half during capture by the slashing motion. Prey choice is therefore limited by the size of the mouth. A sawfish had a catfish in its stomach. In the past it has been suggested that sawfish use their saw to dig/rake in the bottom for prey, but this was not observed during the study in 2012, or supported by later hydrodynamic studies. Large sawfish often have rostral teeth with tips that are notably worn. Old stories often describe"
