An interesting paper came out. Modeling of climate during the peak of the last glaciation shows that dozens of migratory birds in North America had no breeding habitat left whatsoever. Birds probably switched to being sedentary on their tropical 'wintering' grounds and evolved migration again afterwards.
Not commented in the paper, but it looks like birds are far more resilient to changing climate than we thought. And this matches some ultra-fast changes of bird migration seen today.
