Buzzago, very very rare, is typical of Mantua, of Piubega in particular, it could derive from the name of the town of Bozzago in upper Garda, but it is not possible to exclude a derivation from an originated nickname or from the archaic dialect word buzzar (going to crash into something) or an alteration of the term, always dialectal, bozzago (buzzard, a predatory bird).
