from the F.A.Q.

C.A.B.S. (pronounced “cabs”) is a research organization working in the exciting new field of Artificial Birding, which in turn draws heavily from the fields of ornithology, cartography and psychogeography. Hoping to utilize the talents of amateur scientists (like you!), C.A.B.S. seeks to document and map Artificial Birds (ABs) viewable from public space in the Greater Chicago area.
