It is believed that kites first flew roughly 2800 years ago in China. This is because the materials required – silk fabric, high tensile strength silk for flying line, and resilient bamboo, were easily available. Mozi and Lu Ban, two Chinese philosophers of the 5th century, are credited with the invention of the kite.

Bird-watching, the observation of live birds in their natural habitat, a popular pastime and scientific sport that developed almost entirely in the 20th century. In the 19th century almost all students of birds used guns and could identify an unfamiliar species only when its corpse was in their hands. Modern bird-watching was made possible largely by the development of optical aids, particularly binoculars, which enabled people to see and study wild birds, without harming them, better than ever before.
