  • Although great tits can have two broods in a season, now is too late. As you said, it was roosting. I wouldn't be looking for a mate now.

    When nest boxes are in use, esp between about March-June in particular, no one should be touching it.

    For next year, the addition of the entrance panel and 28mm hole will have increased your chances of nesting. Once a bird box is up though, it needs to be left alone, and only handled each Winter for cleaning out.
  • thanks for you’re help do you know if it will return .

  • In reply to Finn:

    Nest boxes need to be left alone this time of year. I don't understand why taking the lid off is an option. Wouldn't it just make it very wet inside every time it rained?
