Yogi is a Corgi with two ducklings, Biggie and Pac. Frances Marsh brought the two ducklings home when they were just two days old. They right away imprinted on Yogi and believe the dog is their 'mother'.
All baby birds imprint on the the first thing they see, which is usually the same species. It's an evolutionary trait based on survival. However, sometimes, when the baby birds are raised by humans the imprinting is transferred.
It wasn't part off Marsh's original plan when she bought the ducklings. Five-year-old Yogi, was in the car that day and immediately fascinated with her purchase. "They were in a little box. He just leaned his head over and licked them," Marsh said.
Why Yogi bonded with the little birds is a bit of a mystery. But Marsh just knows, "He thinks they're his babies."
The ducklings follow Yogi around and look to him for all of their direction and cues. Yogi, in return, has been known to sleep beside the ducklings’ box, herd them gently by pushing them with his nose, and once even barked to alert her that one of ducklings had gotten stuck on its back.
The ducklings have now grown out of their feather down and into adult feathers. They still treat Yogi as the head of the family. As they continue to grow into adulthood, Marsh doesn't know if they will continue to see Yogi as their mom but for now the trio is inseparable.
