A friendly bear waved back at zoo visitors who saluted it.
When Maxim Gavrilenko visited a zoo near Moscow, Russia, he spotted one of the inhabitants sat in its enclosure.
Speculatively waving in its direction, Maxim was surprised when the massive mammal returned the favour multiple times.
Maxim said: “I was stunned when the bear waved back.
“We were told it always does this if he thinks he can get some extra food out of it.”
