Spybirds are reconnaissance and surveillance robots that mimic real birds. Like real birds they fly by a combination of wing flapping and soaring. A combination of solar power and rechargeable power cells allow them to remain aloft for days at a time. At usual observation ranges they are nearly impossible to distinguish from actual birds. The most sophisticated models are actual aviods complete with artificial feathers. Bioroid cyborg spybirds us a combination of electronic and biological components.
Spybirds are a very useful surveillance system since it is seldom practical for an enemy to shoot down every bird within visual range.
