Bird came back from extinction – scientists in glider are teaching it to migrate

Interesting that imprinting on the individual transcends their morphing into this petrol driven creature. Presumably the birds get a sense of "who" not "what" very early on. The drive to both migrate, and follow-the-leader must be strong.

How do they train them to take roles in the lead of the "V" ?

Are they going to have to lead the flock every migration season from now on until a timely death?

It makes me think the pantomime dressing up as Condor might not be needed (which is done to avoid human imprinting I believe: the feeders wear condor-head arm puppets to feed the babies)
