Answer 1

$\large{\underline{\underline{\pmb{\sf{\color{yellow}{Answer:}}}}}}$

Migrating birds may also rely on USWS to rest. The long migration flights of many species don't allow for many chances to stop and rest. But a bird using USWS could both sleep and navigate at the same time. There is evidence that the Alpine Swift can fly non-stop for 200 days, sleeping while in flight!
