If an adult of the same species is not available for imprinting, which of the following is NOT an acceptable substitute?

• A. Juvenile or fledgling conspecifics
• B. Bird puppet
• C. Mirror
• D. Human caretaker

Answer: (D)

Imprinting happens during a brief critical period, and the young needs to form a social bond with a member of its own species to learn normal species-typical behavior, recognition, and care cues. When a real adult of the same species isn’t available, using substitutes that still provide authentic species cues supports proper imprinting. A juvenile conspecific gives real social interaction and appropriate learning of calls and behaviors. A bird puppet can serve as a lifelike model when a living adult isn’t present, guiding the chick to imprint on a bird-like form. A mirror can offer social stimulation when no other birds are around, helping to satisfy the impulse to engage with a conspecific. By contrast, imprinting on a human caretaker trains the animal to rely on humans rather than its own species, which undermines survival and natural behavior after release.
