Bluetits

We moved into our new house the end of March and our new garden is huge and very wildlife focused. We found that bluetits had been born in one of the bird boxes and weve spent the last two weeks just loving the whole experience, i've been on here to research as we had no clue about any of the process so thanks to this website i've clued up a bit. The babies were approaching the exit so i knew fledging was imminent and it was today. They have left the nest and are in my nearby hedge, its been the most wonderful experience. So now they have fledged today, do they go back to the nest or is this it? i'm going to miss them, ha ha.
