I've often wondered if some long-distance (global) migrants, e.g. waders or
passerines, go into torpor while soaring on wind currents at high altitude.
It would be an effective means of conserving energy when flying
long-distances, at low ambient temperatures and oxygen levels (provided that
they are not blown off course in the process).

Yes but measuring in-flight energy consumption of long-distance migrants in
real-time during their migration is definitely a step on.
