Answer: the heaviest bird in the world is the Argentine giant eagle. Its maximum weight can reach 72 kg. It is known as the second largest bird in the world. Its spread wing length is only 0.2 meters less than that of the first San's pseudotoothed bird, and its maximum length can reach 7 meters. Although this bird has a huge body, it only eats animal carcasses or catches small prey.
The heaviest bird in the world: the Argentine giant eagle. The maximum weight of the Argentine giant eagle is as high as 72 kg, which is equivalent to the weight of 16 vultures. The standing height can reach 2 meters. After the wings are fully unfolded, like a light aircraft, their eggs alone exceed 1 kg. However, the Argentine giant eagle does not prey on large prey because their jaws are underdeveloped, It is difficult to tear up medium and large prey. Like vultures, they can only look for animal carcasses to survive. Habits of the Argentine giant eagle the Argentine Giant Eagle lived in the Miocene 60 million years ago. The fossil of this bird was first found in Argentina. Scientists calculated that the flying mode of the Argentine Giant Eagle may be gliding. Because it is too large, it needs to use the updraft on the grassland to complete the flight, but as long as it flies, the speed can even reach 107 kilometers per hour, When landing, it is likely to use huge feet to slow down.
Because the fossils of birds are hollow, it is difficult to find complete bones, and the Argentine giant eagle is no exception. Most of them are spliced by scientists through scattered fragments. From this, it can be inferred that the life span of the Argentine giant eagle can even reach 100 years, because their reproduction and growth are slow, and it takes more than ten years to reach full adulthood, Eggs are laid about every two years.
