This video from the USA says about itself:
Large condor regularly visits man who saved its life as a baby
13 June 2017
The condor was nursed back to health by the man after the bird fell from his mother’s nest as a baby.
After being rescued, the condor – the largest bird in North America – was then able to learn how to fly and return to normal life.
It is not unusual for the condor to fly back and visit its rescuer, and according to locals the bird is said to return to visit the man fairly frequently.
