Answer:
California woodpeckers
Step-by-step explanation:
Woodpeckers are a group of birds found all over the world, including in California. In California, some of the common species of woodpeckers include the acorn woodpecker, the downy woodpecker, the hairy woodpecker, and the Nuttall's woodpecker. These birds are known for their ability to drum on trees and other objects to communicate with other woodpeckers and establish their territory. Woodpeckers in California are also important members of their ecosystems, as they help to control insect populations and provide cavities for other animals to use for nesting.
