Study Shows Songbirds Switch From Bugs To Berries To Fuel Fall Migration
...n. Switching from insects to fruit offers migrants advantages beyond increasingtheir energy intake, Parrish suggests. Because fruit is clumped in specificsites, migrating birds spend less time and energy searching for food.
