Given the symbolism of doves, this may imply the pope is peace, Fidel Castro in Cuba used a similar event to promote his power base. The pope however links it to his office, and his residence not himself!
AFP: "VATICAN CITY — A pair of doves seemed to prefer the company of Pope Benedict XVI to the great outdoors on Sunday when he had trouble convincing them to take flight in a traditional peace gesture.
The first dove hesitated on the windowsill of the pope's Vatican apartment for a long spell before flying off, while the second flew back into the room before flying out again."They want to stay in the pope's home," Benedict said, flanked by two children."
