Can anyone tell me what's inside my bird box?

  A wasp nest?
  Watch it in the hour before dusk and see if there are wasps returning home …

  We had tree bumble bees nest in an old nest box last year. They were active during the day so you would notice them so maybe as @Dovefromabove suggests could be a wasp nest.

  Or possibly the beginning of a hornets’ nest …

  I’d just keep a respectful distance and watch and learn. Fascinating 😊
