Blue tits in the High Weald

Hello Sheena, what a disappointment to have a blue tit start to nest and then disappear.  Maybe she will return  .  If not welcome to my club the no nesters.  I also am just having to keep up and enjoy others having nests.  I do get a lot of enjoyment from it even though it is nothing like having your own to watch.  Things may still turn around for you, good luck.
