Optimum fuel loads in migratory birds: distinguishing between time and energy minimization
TLDR
The total energy cost of migration is roughly divided between flight and stopover as 1:2, probably with a relatively longer stopover time in larger species and strong selection pressures to optimize the fuel accumulation strategies during stopover episodes are expected.About:

Long-distance migration: evolution and determinants
TL;DR: From this expos it is clear that research on migration warrants a multitude of techniques and approaches for a complete as possible understanding of a very complex evolutionary syndrome.

TL;DR: It is proposed that this transoceanic route of bar-tailed godwits may function as an ecological corridor rather than a barrier, providing a wind-assisted passage relatively free of pathogens and predators.

Avian metabolism: Costs of migration in free-flying songbirds
TL;DR: The results confirm the counterintuitive prediction that songbirds expend double the amount of energy during stopovers that they spend on flight over their entire migration.

Birds: blowin’ by the wind?
TL;DR: In this paper, a review brings together numerous theoretical and empirical studies investigating the flight behaviour of migratory birds in relation to the wind, concluding that birds select for favorable wind conditions both at departure and aloft to save energy and that for some long-distance migrants a tail-wind is an indispensable support to cover large barriers.
