How to Speak Mockingbird! The Northern Mockingbird is a small bird about the size of a Blue Jay. And they can have around 200 different songs, none of which is truly their own. They can copy other birds, frogs, and even car alarms. They also have some alarm calls. A “chat” call when disturbed. And a “chew” call when scaring off large predators.What are the mockingbirds saying near you? #naturalists #naturalistlife #naturalistic #natureeducation #birdsong #northernmockingbird #mockingbird #sounds
