Blue Jay VS Yellow Bear Caterpillar
This blue jay tried to make a meal out of this yellow bear caterpillar but the caterpillar's defense system worked to let it live another day.
Yellow Bear caterpillars are the larvae of the Virginia Tiger Moth. When threatened they will curl up into a ball which make the prickly hairs stand straight out. This makes it very hard for most predators to turn them into a meal.
