To do this they shrink their liver, kidney and gut
Only the organs essential for long-distance flight are maintained.
They use a mental-maps for navigation which almost certainly includes star-charts and beak-compasses.
The birds follow patterns of movement engrained into a culture that evolved with the ecosystem they inhabit today,
