You can be sure every animal in the world certainly has its own defenses to survive predator attacks. So is the bird, one way to survive the most common birds avoid attacks by predators by flying. However, in addition to flying birds have turned out any other way to avoid predators. Birds that have a remarkable defense of which is ;
Bird Burrowing Owl.
These birds are often found in grasslands and deserts from Canada to Patagonia. They nest in burrows and often use abandoned burrows of other animals, but if they can not find an empty hole, they can also dig their own holes. Burrowing Owl Children are often left alone in a rut and have to hunt for themselves. During this time, the children are vulnerable to predators such as foxes, coyotes, raccoons and house cats. In order to keep the enemy away, immerse children Burrowing Owl has developed a process of mimicry. When they feel threatened (for example, if the animal began digging at burrow entrances), the child produces a snake-like hissing calls when warned his enemies. Due to the highly venomous viper known to hide in burrows, mostly predators (including humans), preferring to run away as soon as they hear it. Their defense mechanism is one of the most efficient among the birds, but it has a weak point, it is useless against actual rattlesnakes. It certainly can not deceive them and the fact that rattlesnakes is deaf.
Ferruginous Pygmy Owl Bird.
Although owls normally known to prey on mice and other rodents, it turns out they also hunt fellow owls and the smallest are usually afraid of owls, when they see an owl during the day (when the owls tend to be less willing to carry out a surprise attack), they scramble for bothering to push it away. This behavior is known as "mobbing". This owl is a skilled bird hunter, taking prey up to twice their own size, and therefore they are feared by all other small birds in their area. Of course this is very dangerous for the smaller species such as Ferruginous Pygmy Owl. To protect yourself from mobbing, this bird has 2 spots on the back of his head that resemble eyes. It is enough to deter most small birds, because they usually will not attack the owl who looked at them. If the face of larger birds, surrender may be better.
Killdeer bird.
Bird is a rather noisy and often found in Canada, the United States and Mexico. They nest on the ground so its eggs and chicks are very vulnerable to predators. To protect their nest, the adult killdeer has developed a clever technique, when ground predators such as foxes, cats or dogs approached the nest, the adult birds will move away from the nest, dragging one of its wings as if it has been damaged and pretended to seek help. Most predators will chase the adults who seem helpless, then the predator has unwittingly away from the nest. After the adults feel safe to fly immediately. As for children killdeer, they will run away when the predator distracted by the adult.
Potoo birds.
Often found in Mexico, Central and South America, this bird is a strange nocturnal predators also known as "Ghost Bird", because of their remarkable camouflage. Potoo eat insects, small flying animals such as bats and small birds. In potoo daytime roost in trees and keep moving really mimic tree stumps and dead or like a broken stump. Its fur resembles eyelid skin and the wood has a crack that allowed her to see even when the eyes are closed. Potoo will usually still move even when approached by another animal (or human) and they only fly when they feel that they have been known to disguise. This camouflage is so good, however, they are almost never found and they have almost no predators. It also makes it very difficult to Potoo we observe. At night Potoo can only be found because his eyes reflect light, shining like a cat and owl.
Hoopoe bird.
Found in Africa, Europe, Asia and recently elected as Israel's national bird. Hoopoes have special glands near the anus, which produce a foul-smelling substance. The bird rub this substance on its feathers, which will cover the entire body with a smell like rotten meat. Not many predators that eat birds attracted to stink. This substance has two functions, it acts as a parasite repellent and as an antibacterial agent and protects birds from various diseases. Interestingly, adult hoopoes produce this fluid only when incubating the eggs, after his son left the nest, he quit producing this substance. The Hoopoe small, they have their own methods of defense, when threatened, they squirt the dirt right into the face of the predator. And this is a very effective technique to ward off unwanted visitors.
African Bird White Masked Owl.
This little owl little known to the public after recently when a Japanese TV show featuring an incredible defense method. If approached by enemy small bird will hiss to make himself look bigger and ferocious, this is a defensive method common among owls and apparently enough to scare the enemy. However, when dealing with an enemy that is larger and more powerful, these owls are not trying to scare him that way, but leveling so the feathers and squinting his eyes almost invisible to predators. By keeping these birds move to do something to resemble a tree stump or branch plants, such as Potoo, escape from larger predators.
Birds Fulmar.
These birds include sea birds. Fulmar is derived from the Norse word, meaning "foul gull". These birds are known for their foul smell, not just the stench of his body, even the eggs they also smelled. Fulmar egg shells are housed in one of the museum collection was issued after 100 years of smell saved. Can not fly or run away from danger, Fulmar chicks develop an amazing defense mechanism. When threatened, they spit out some sort of bright orange liquid oils that not only smell bad, but also stick to fur predator. This oil makes raptor feathers become matted, so lose their insulating properties and drown if submerged in water. This makes it dangerous for child predators Fulmar. The Fulmar has fur that is "immune" to oil, it is very important because not only spit on Fulmar child predators, but on every animal that approaches, including holding their own, they just started to recognize their mother when they were about 3 weeks old.
Birds Hooded Pitohui.
Found in New Guinea, their defense against predators that despite their simple but stunning is toxic. Pitohui consuming some types of beetles that contain a potent neurotoxin and contains an alkaloid known as batrachotoxin (poison were also found in the skin of poison dart frogs of South America). By eating beetles, birds become toxic, toxins they are on their own fur and skin. They actually known by the locals as "trash birds", because of their toxicity makes them impossible to eat unless they removed the skin and fur. Touching Hooded Pitohuis can cause numbness and tingling, burning skin and sneezing (as reported by the scientists who deal with the creature), while consuming they may be much more dangerous. To warn the nature of its toxicity, this bird has a bright orange color and black colors which enables candidates to recognize predators. And it is believed that the Hooded Pitohuis can rub the eggs and their toxins to protect them from predators.
Eurasian Cuckoo Bird.
Known as the birds often lay their eggs in the nests of other birds. When a child is born, he destroys the eggs of birds actually nest occupant, thus eliminating any competitors and rapidly growing compared with children of the adoptive parents. To protect themselves from threats, female cuckoo has developed a performance very reminiscent of a Sparrow Hawk, a raptor that eat small birds. And supported by the similarity of the two. By masquerading as Sparrow Hawk, Cuckoo could scare other birds away from their nests so. During the fake Sparrow Hawk was there, the other birds will not be able to return to their nest and cuckoo can lay eggs without a problem. There are several other species that imitate the cuckoo but not just mimic hawks, such as Hawk-Cuckoo in South Asia that mimics the type of local sparrows, flew up to the style and even how to perch.
