Data from: Solar heating may explain extreme diel flight altitude changes in migrating birds
Great reed warblers Acrocephalus arundinaceus and great snipes Gallinago media exhibit a diel cycle in flight altitudes, flying much higher during day than night, when performing migratory flights covering both night and day (Fig 1). One hypothesis proposed to explain this behaviour is that the bird...
