Which option is NOT an imprinting substitute when raising orphans?

• A. Juvenile conspecifics
• B. Bird puppets
• C. Mirrors
• D. Human caretaker

Answer: (D)

When raising orphans, the goal is to provide social and behavioral cues from sources that won’t cause the animal to imprint on humans. Substitutes like juvenile conspecifics, bird puppets, and even mirrors give the young animal target stimuli that resemble peers or parents of the same species, helping it learn normal social and species-typical behaviors without forming a bond with people.

A human caretaker, while essential for feeding and care, does not serve as an imprinting substitute. Direct human contact can lead to imprinting on people, which makes later release impossible or dangerous because the animal may seek humans or fail to integrate with wild conspecifics.

So, the human caretaker is not an imprinting substitute, whereas the other options provide social stimuli that can guide appropriate behavioral development.
