bee advice

hi, not sure if posted in right place... we have 2 birdboxes on house wall. sparrows did check it out but have,nt used this year. thought we had seen bees going in and out but were,nt sure. confirmed today by a magpie standing on top pecking in box then the bees came flying out. one bee must have been pecked and fell to ground has not moved all day. now ants are trying to take it away. it has white bottom,black body and orange head,just gone and moved it and it has a baby bee under it, have now put them away to safety. does anyone know what they are doing in birdbox or is it normal that they use them. my son says they are bumble bees not honey ones. thanks for reading

Congrats on your new residents. They'll be fantastic for your garden. Magpies, on the other hand, are a menace and make a right racket. Maybe you could put something on top of the box to deter it from landing on it.
