SPACETIME CARRIER PIGEONS go through a Time Bureau training and life-extension process similar to that of humanoid Time Agents.

“Pigeons” is a misnomer as birds of all types are used for Time Bureau operations. More intelligent breeds of birds are capable of more complex missions.

Some but not all UFO sightings are actually SPACETIME CARRIER PIGEONS flying against the stream of time. The “luminous” quality of objects traveling against the stream of time is actually more of a “shininess” resulting from “reality cloaking” technology. Reality cloaking technology deflects most physical forces off of the time traveling object like a mirror. Deflected forces include but are not limited to: light, gravity, electromagnetism, and most important to the purposes of time travel: entropy.
