L'uccello migratore (The migratory bird) is a 1972 Italian comedy film directed by Steno and starring Lando Buzzanca and Rossana Podestà.

During an outdoor lesson he receives a letter from his uncle, a politician who lives in Rome and who, thanks to his interest, managed to get him a transfer to the capital's high school.

Arrived on the spot, he meets his uncle who offers him an apartment, but on one condition: this must also act as an alcove for the faithful encounters of the same honorable, as he is married.

In order to avoid inappropriate encounters, the two agree with a system: showing the Italian flag from the balcony means that the house is already occupied.

Andrea's first approach with his colleague Delia Benetti and the students is not happy, as he has replaced Professor Verdirame, much loved by the boys.
