A research group led by Associate Professor Masaki Eda of the Hokkaido University Museum has found that pelicans and hook-billed herons that do not live in the vicinity are depicted in the world heritage site "Nasca's Ground Painting" in southern Peru, South America. rice field.The research group believes that it may lead to the elucidation of mysteries such as the purpose for which the geoglyphs were drawn.
According to Hokkaido University, the research group analyzed the shapes of 16 birds drawn on the geoglyphs from the perspective of ornithology and compared their characteristics. Although the type of 13 points could not be identified, the 2 points that were previously thought to be condors and flamingos were judged to be pelicans based on their crests, hook-shaped beaks, and protruding chests.
One point that has been regarded as a hummingbird so far was identified as a hook-billed heron because of the protruding central part of the tail feathers and its elongated beak.
Pelicans live in the coastal area about 50 km away from the Nasca plateau where the geoglyphs are located, and hook-billed herons live in the eastern and northern parts of the Andean mountains to the east of the geoglyphs, and live near the geoglyphs. No.
Nazca's ground paintings are drawn in the desert area between the Andes and the Pacific Ocean, and are one of South America's leading tourist attractions because they are so huge that they cannot be seen without flying over them.
It is thought that it was drawn in the Nasca period from 200 BC to about 800 BC, and more than 700 ground paintings such as geometric patterns and those that are thought to have drawn animals have been confirmed, but the purpose of drawing is Many hypotheses such as the astronomical observation theory, the rainy weather theory, and the spacecraft landing site theory have been made unclear.
