This is the first of two full moons this month. It is known as the Worm Moon. It’s the time of year when earthworms start showing up.
It is also called the Sap Moon since the sap is starting to flow in trees now. It marks the time when Maple trees should be tapped to make syrup.
Northern Native tribes also called it the Full Crow Moon. The cawing of crows now signals the end of winter.
