A Companion for The Milk Hill Alien?

At first sight a Swallow comes to mind with memories of last years flock of Swallows that appeared in the same field but there is an echo in this formation of the beautiful Swallows of 2003 that appeared below Adams Grave. 

On the other hand this could be an Alien companion for the nearby Milk Hill formation that appeared recently in two stages over two nights. 

The wheat crop is still a little on the early side and this formation may well benefit in its appearance when the crop becomes a little more golden and mature.
