polenta e osei
a main course, or a little cake
Unlike uccelli, if the main menu lists osei, it really does means little birds such as thrushes and larks. They are spit roasted with sage until they are crunchy and can be eaten whole, including the bones, and laid out a mound of polenta.
The dish is, or was, so popular that in Bergamo (especially) they also make little cakes of the same name, with pan di spagna, filled with cocoa flavoured cream and rum, and topped by little marzipan birds and honey.
