Chubby birds get there faster
Date:2/17/2010

that fat garden warblers only waited until nightfall on the same day to move on. As opposed to this, the lean birds had to wait until they had accumulated sufficient fat reserves for the next leg of their journey." The data demonstrates the importance of ecologically-intact resting grounds: The birds can only replenish their energy reserves quickly and move on to their breeding grounds swiftly and unfailingly if they can rest in areas with sufficient supplies of insects, nectar and pollen. Those that arrive early at the breeding ground can secure the best nesting sites.
