Amongst UFO theorists of the more conspiratological, government cover-up kind, 'the Aviary' is taken to refer to a group of individuals, often with ties to existing intelligence agencies, or being well-placed in UFO media outlets, with an ambiguous role, either one of 'preparing the public' for future UFO revelations, or spreading disinformation in order to keep people guessing about the true nature of UFO phenomena.

They crop up mostly in the MJ-12 or Majestic 12 mythos concerning various purported groupings of top-level government advisors formed in order to combat the UFO menace (or sell us down the river to the aliens, etc., depending whom you believe) which seems to emanate from the strange, tangled, goings on between reputed AFOSI (air force intelligence) agent Richard Doty, Paul Bennewitz (a UFO researcher who was, amongst other things, trying to receive alien communications by writing a computer program to 'decode' radio noise) and (slightly more reputable) UFO investigator William Moore - himself an ex-AFOSI (Air Force Office of Special Investigations) staffer.

In a 1991 article for Fate Magazine, and, I believe, at a UFO conference (MUFON) around the same time, Moore shocked the UFO community by claimed to have been working with a group of government disinformation agents, actively passing on their contaminated information to other researchers, in exchange for real information which they promised to release to him concerning government knowledge of UFOs. This disinformation group was given the name 'the Aviary' in Moore's article.

Each member is thought to have a 'bird-name' - a codename which is the name of a bird. Here's a list, which has some nice biographical details, quoted from a 1996 article by Richard J. Boylan, Ph.D., which has been influential in the field. There are many different lists in circulation, so you shouldn't take this as more than a representative sample. Still, it has all the main names in it. I think the attribution of particular positions within agencies such as the CIA should be taken with some caution, though a lot of the biographical information provided is correct, in terms of institutional affiliations.

Amusingly, Aviary story originator William Moore gets a mention as a member in this version of the list!

BLUEJAY
Dr. Christopher "Kit" Green, MD, Ph.D., Chief, Biomedical Sciences Department, General Motors; former custodian of the CIA's UFO files at the "Weird Desk"; received the National Intelligence Medal for his work on a classified project during the period of 1979-1983; recently reported to be White House UFO liaison.

RAVEN
(Identity not yet determined.) RAVEN appears to be a kingpin in The Aviary, and a Washington insiders' guessing game has sprung up, as devotees of UFO intelligence data argue for the probable identity of their favorite "candidate".
