The breast-bone is very large, with a prominent keel down the middle, and is formed for the attachment of very strong muscles: the bones of the wings are analagous to those of the fore-legs in quadrupeds, but the termination is in three joints or fingers only, of which the exterior is very short.

The present occupants are an assemblage of German owls, of varied species; they look analagous with the venerable ruin.
