Whether this is a true case of social learning, with young birds picking up migration savvy from flying with older ones, is a question that intrigues behavioral biologist Dora Biro of the University of Oxford in England. Youngsters might not be learning from their flight mates so much as benefiting short-term from the older birds창��혲 expertise. The difference is not just semantics, she says, but is important for understanding how generations might be transmitting information about migration. |
