Tree bumblebee orientation flight

Earlier today a great tit was busy pecking at the new bird/bee box entrance. Recently they regularly chase away the blue tits whenever they go near it during the day. It has been used over the winter by a blue tit for roosting….I saw the queen go inside late pm today and stay for 8 minutes, checking the decor no doubt! Whether she returns is another question! Just been told that another queen went into a ground surface nest box I have…….a large black and yellow specimen! Wait to see that if I can tomorrow!
