God made the eagle with all its advantages. Besides being able to survive for decades, these predators are also able to capture prey with beautiful movement and deadly. Greatness does not come suddenly, but obtained through a natural process that is painful and exhausting. Proverbial, falcons also underwent behavioral doubts about the alias “imprisoned” to get various advantages. Not surprisingly, Suzanne Kane, scientists from Haverford College in Pennsylvania compelled to examine these unique animals. As reported by The Guardian recently, scientists put the camcorder in the head and back eagles to observe the movement of these birds, especially when the ambush prey.
Interestingly, the observations reveal how hebatan eagle while flying, chasing and killing its prey. Kane said the eagle did not directly attack the prey but chose to focus first slide approaching prey. This strategy utilizes an effect called motion camouflage, where predators do not seem to be moving from the viewpoint of prey. Eagles will look as if he was floating motionless. Video footage also showed what was observed by an eagle while hunting crows. “They came very quickly and use their claws to kill the bird (crow) or they (the eagle) very quickly break its neck,” said Kane, who is also interested in observing how birds of prey can avoid ambush predators.
Kane hope this study can help developers to create powerful robot that can fly in the air. Heat bloody eagle or eagle is one giant carnivorous birds, especially the genus of the tribe Accipitridae Aquila. Eagle classified as warm-blooded animals, have wings and body are covered feather fronds. Breed by laying eggs that have a hard shell in the nest made. He also keeps her until able to fly and find food themselves. The main meal eagles are small mammals such as mice, squirrels, lizards, fish and chicken, as well as other types of insects depends on the size of his body. Part eagle toothless, but curved and strong enough to rip the meat prey. This bird has a pair of sturdy legs with sharp nails and curved for grasping prey.
Sharp eyesight can hunt prey from a distance immeasurably. Eagles have good respiratory system and is able to provide the amount of oxygen that is much needed when flying. Eagle heart consists of four chambers like humans. Upper chamber known as the atrium, while the lower chamber known as the ventricles. Eagle imprisoned including long-lived birds, can reach 70 years. One secret, at the age of 40 years is a critical phase. Paws began to ripen, the beak becomes long and bent almost touching his chest. Its wings are very heavy, because his fur grew thick, making it difficult to fly. At that time the eagle through the process ìbertapaî very painful and lasted for 150 days. Eagle strive to fly to the top of the mountain and make a nest on the edge of the ravine and then stay there. A number of phases must be passed by this beast. At first dipping its beak eagle on the rock until the half apart, then silence while waiting for a new beak growth.
The new beak to grow it is used to pull out one by one cakarcakarnya and should remain wait until the new claw grows again. The last phase is the most painful plucking feathers all over his body one by one. Five months later the new hairs start to grow and eagles can fly again as usual to meet life 30 years later.
