All kinds of birds chirp like a blue jay and cardinal and other birds...etc.
Birds sing to protect territory and attract mates. They chirp and vocalize in other ways to communicate where there are, where there is danger. Birds talk to birds and human talks to humans:)
A bird that calls chirp chirp trill chirp chirp trill...
Will, if they chirp then nothing will happen. Honestly, its not like something bad is going to happen to the bird or to the world.
