What diet shift occurs as migration looms for warblers?
Answer
A greater reliance on fruits and seeds for energy storage
When warblers prepare for or undergo migration, their dietary focus shifts away from the high-protein insect consumption necessary for nesting activities. This transition is essential for energy storage required for long-distance flight. Fruits and berries provide the necessary high-energy content, often containing beneficial fats and sugars that serve as efficient fuel reserves, contrasting sharply with the protein focus needed during the breeding season when they are feeding growing nestlings.
