Earthworms in Spring

In spring as the soil thaws down to the level of the estivating worms, their bodies start to work again and they start eating. During cool, moist days, they can often be found at the surface, making them a convenient food source for robins! But the hot sun often drives them back into the soil. They emerge at night, when the air is cool and moist, to feed on decaying organic matter at the top of the soil.
