Wilson's Warbler Enjoying a Caterpillar
Our native Amelanchier trees, also called shadbush, juneberry, or serviceberry, do double duty as a food source for birds. Their berries are much-loved by many avian species. Just as importantly, the caterpillars they host are essential bird food, especially in the spring— high in protein and full of good nutrition. This Wilson's Warbler is eating the caterpillar in mid-May, even before the Amelanchier berries ripen.
