Is it true that mother birds are frightened by human scent and will reject a baby if touched?

Is it true that mother birds are frightened by human scent and will reject a baby if touched?

• A. False. Birds have a poorly developed sense of smell, and gloves should be worn to prevent disease transmission.
• B. True. Mothers will reject any baby touched by humans.
• C. It depends on the species.
• D. Only if the baby is a nestling.

Answer: (A)

The claim tests a common myth about avian parental behavior. In most bird species, the sense of smell is not a strong factor in recognizing or rejecting their young, so human scent is not a reliable cue for a mother to abandon a chick. Therefore touching a baby bird does not automatically cause rejection simply because of odor. In rehabilitation practice, the safer approach is to minimize handling, and when handling is necessary, wear gloves to reduce disease transmission and avoid transferring oils or odors to the bird. While there are exceptions among some species, the general principle used in most settings is that human scent alone is unlikely to trigger abandonment.
