California Nursery Historical Park has many old trees that are ideal for Owls and other Raptors to roost, nest and hunt in search of food. Bring your flashlight and walk with us through the grounds at dusk — a good time to spot an owl in the trees or hunting for prey. Meet at the California Nursery Office for an introduction to owls and then walk as the sun goes down while you will look and listen for the raptors that hunt at night. Discover owl pellets and the bones of what the owls ate at the Vallejo Adobe. Other family members (adults and kids) are invited to register. Other night birds may be present in this urban forest.
