What food source might Vermilion Flycatchers supplement with during winter months?

Answer

Berries or fruit

Although their diet is primarily insectivorous, it is not static throughout the year. During winter or periods when insect availability decreases, they may turn to small fruits or berries to provide a necessary carbohydrate boost and sustain their energy requirements.
