IC 5146, The Cocoon Nebula (Sharpless 2-125, Caldwell 19) in Cygnus, is a star-forming nebula that lies about 4000 light-years from Earth. It is similar to the Trifid Nebula. The central star formed about 100,000 years ago. The emission nebula is surrounded by the dark nebula, Barnard 168. To me, this would also qualify to be named the eagle nebula. The dust superimposed in front of the lower left portion of the nebula looks like the head, neck and open beak of a screeching eagle, complete with eyeball in the socket.
