A garden center in Newport Pagnell, England was forced to block off a display of birdhouses that it had for sale, after a pair of blue tits decided to hijack one and build a nest inside it, the Daily Mail reports.

Apparently, they didn’t bother paying for it either.

The store manager, Nina Konig, took it all in stride, and blocked off the aisle, so people wouldn’t disturb the nesting pair stating that it was a ‘resounding endorsement’ of their birdhouses.

‘They seem to have settled in very well,” Konig added, “and are unfazed by the hustle and bustle of a busy shop environment.”

Apparently, the pair have also been stealing seeds at the garden center and are not beyond breaking into sealed bags if they aren’t particularly enamored by what is lying around.
