Just had this message from a birding mate about the stork. (I'm guessing this will relate to your question about being in Knepp):
Stork news, apparently the ringed Knepp bird was a lone bird but recently went to Spain, so it seems the unringed bird it’s now paired to is most probably a wild one?!
A first for me today on my lunch hour. Two white storks circling lazily overhead. Glad I chose to sit outside today!
