Buss and Meyer define fibrations of topological groupoids and interpret a groupoid fibration L --> H with fibre G as a generalised action of H on G by groupoid equivalences. My result shows that a generalised action of H on G may be transported along a Morita equivalence G ~ K to a generalised action of H on K, which is given from a fibration R --> H with fibre K. Furthermore, topological groupoids R and L are Morita equivalent.
