Most migrants feed intensively before leaving, to build up stores of fat for the journey. Sedge warblers take this to extremes. Sometimes these small birds double their weight, storing fat even under the eyelids, becoming almost spherical and hardly able to take off. They cross the Mediterranean and Sahara in one hop to tropical Africa.
