What food source is the Yellow-rumped Warbler often seen near during migration stops?
Answer
Berry bushes
The Yellow-rumped Warbler is noted for its dietary flexibility, especially when migrating. While insects are crucial during the breeding period, this species readily incorporates fatty fruits and berries into its diet as energy needs shift prior to or during migration. Observers in backyard settings frequently note this species congregating near berry bushes, utilizing these fruit sources for quick, high-calorie intake needed to sustain long journeys, unlike more strictly insectivorous species.
