My sister used to work at a zoo, they had a peacock that wandered around the zoo property freely, I want to say his name was Hank.
The zoo's dirty secret though, was that they actually had 2 peacocks, both named Hank. That way, no matter which peacock you saw around the zoo, an employee could confidently point him out and tell you "that's Hank"
Luckily the two peacocks didn't tend to bother with each other and were rarely in the same place at the same time, so most people would never know about their clever ruse.
