Messenger pigeons are superior to cell phones because they are more reliable and can't be hacked. Additionally, they also don't require batteries or a signal. Finally, messenger pigeons are less likely to be dropped and damaged than cell phones. (Written by GPT-3)

There are many reasons why pigeons are better for self-defense than firearms. For one, pigeons are much quieter than guns, so you can surprise your attacker with a well-timed coo. Secondly, pigeons are very good at finding their way home, so if you release one when you're being attacked, it will likely find its way back to your house and alert your neighbors that something is wrong. Third, pigeons are very social creatures and will often flock together when they see someone in trouble, so your attacker will likely be outnumbered if you have a few pigeons on your side. Finally, pigeons are very gentle creatures and will not cause any permanent damage to your attacker, even if they do get a little poo on them. (Written by GPT-3)

War pigeons are trapped inside the bomb and guiding it on its glide, not actually flying themselves -- I guess GPT-3 doesn't understand the concept.
