Scavengers in nature - scavengers

Sometimes we tell children to "clean the plate" or let them eat the food on the table. In the wild, predators don't eat their prey completely, but nothing is wasted. There will be many animals "cleaning up" leftover food, or breaking down organic matter so that it can be used by other organisms. Carcass-eating scavengers feed on dead animals, not by killing and hunting live prey. They can eat much of the scraps left over from predators, and they can also eat the carcasses of animals that have died for other reasons. Hyenas and vultures are two common scavengers. Scavengers are notorious for feeding on carcasses, yet they provide essential services to the natural world. Decaying carcasses attracts disease-causing organic matter, such as certain bacteria, and if scavengers don't eat most of the remaining animal carcasses, the decomposing carcasses can contaminate the soil and adjacent water sources. The scavenger shreds flesh into smaller, more decomposable pieces, thereby speeding up the process of decaying the carcass. Hyenas waiting for scraps Hyenas are one of the most common scavenger mammals. While it's true that hyenas can hunt their prey on their own, they don't shy away from other predators—especially leftovers from lions. The hyenas watch closely while the lions hunt, and if many lions gather around their prey to feed, the hyenas will wait until they abandon the food. Then the hyenas swarmed to grab the rest of the food. However, sometimes there may be only one or two lions taking prey, and if the dogs are large enough, they may keep harassing and attacking the lions until the big cats have to give them food. They eat parts of their prey that lions don't. In Africa, where hyenas live, they do a lot of "cleaning" work. Carrion Among Birds On this continent and almost anywhere in the world, vultures and similar birds feed on carrion, also known as carrion eaters. Vultures have extraordinary eyesight, and like eagles, they watch from afar for food that may appear below. The vultures also pay attention to each other. When a vulture flies to the ground, the other vultures know that it has found food, so they all fly with them. That's why, seemingly in the blink of an eye, swarms of vultures appear next to a dead animal. Other scavengers, such as storks and other vultures, pay attention and follow vultures. A vulture that suddenly swoops into fresh animal carcass provokes a cascade of responses, other scavengers and ground animals rush towards the carcass, and even predators take advantage of the "I found food" from the swooping vulture "signal of. Lions and some other predators also eat dead animals. Most vultures feed on the soft tissues of carcasses, such as meat from muscles and organs. Some vultures only eat certain parts of the meat, such as skin and tendons. All vultures and most other scavenger birds have long, sharp, curved beaks to tear apart pieces of meat, and some long bald necks that allow them to burrow into carcasses and extract organs. Animals give in to each other for carrion. A flock of feeding vultures may be chased away from their meal by a lion, and the vultures will patiently wait for the lion to fill their stomachs. As soon as the lions left, the vultures rushed forward again, however, they may be driven away again by other ferocious carnivores. Storks are also scavengers, they can grow up to 1.52 meters tall and have a wingspan of 2.44 meters. The stork's beak is not curved, but is long and straight, and can be used to reach into the interior of the carcass and tear off large pieces of meat. Small vultures that are eating carrion will be replaced by large vultures, which will be replaced by storks, which will be replaced by hyenas, and so on. Usually, each type of scavenger leaves some uneaten food, so there is always something to eat for each type of scavenger. Carrion-eating bald eagles and the national bird of the United States When America's founders discussed which bird should be used to represent the United States of America, many objected to the use of the bald eagle. Despite its noble appearance, some of its habits, such as eating carrion, disgusted some early leaders. Benjamin Goranklin believed that the selection of the bald eagle as the national bird was a major mistake, and his suggestion was to choose the turkey. While the turkey has many good qualities, people say it doesn't look like a mighty animal. In the end, the voices of bald eagle supporters drowned out Franklin's opinions and became the national bird of the United States. Animals die in every animal's habitat, and other animals feed on their carcasses. On the coast, crabs are the most numerous scavengers, using their claws and claws to break apart and eat the remains of animal carcasses. On the seafloor, lobsters often scavenge. Carcasses of dead animals decompose particularly rapidly underwater, where detrital feeders play a major role in the degradation of carrion. Scavengers are nature's scavengers, cleaning up animal carcasses to prevent some dead animals from spoiling and spreading germs.
