Caped Somnium Chickens

These odd, one-eyed birds have startled the biological community. They were briefly seen and sketched just a few weeks ago in September 2012. They have a marvelous way of maneuvering their bodies and "capes" (particularly nimble and extendable wings and plumage) so that they appear as they might in a dream - the observer recognizes they are chickens (of a sort) despite not having many plausible chicken-like features.
Note the middle bird is carrying her young in a specially evolved wing pouch.
