The Vatican regularly releases doves as a symbol of peace, and in multiple instances they have been chased and sometimes captured and killed by more aggressive fowl in the area. But the events on Jan. 26 were more noteworthy because the scene of a seagull and a crow swooping in to attack the doves was captured by several of the photographers in St. Peter’s Square as a crowd of tens of thousands — including several thousand children — looked on.

Both white doves managed to escape their predators after a brief tussle, but it’s unclear what ultimately happened to them.

In an open letter, the National Animal Protection Agency in Italy said that because the doves are bred in captivity and lack strong survival instincts, releasing them into the wild as is often done at the Vatican “is like condemning them to certain death.”

The statement called for the Vatican to change its policies: “Do not use animals and their lives any longer for these outdated traditions,” the group said, adding that it planned to launch a petition to gather signatures in order to formally ask the Vatican to halt the practice.

The Vatican did not immediately respond to the call for change from the group, best known by its Italian initials ENPA.
