The common name derives from 'jack' meaning small, and 'daw' which is the vernacular English name for the bird. The Latin specific name comes from moneta, meaning 'money'.
They cause a bit of a nuisance when they attempt to nest in chimney pots. Lots of houses in town have wire mesh covering them to prevent this. One of it's dialect names is the chimney sweep bird.
