What kind of noise does a pigeon make?
Their main sound is used by males to attract mates or defend their territories: coo roo-c'too-coo. The call they make from their nest is oh-oo-oor. A pigeon call of alarm is oorhh! Baby pigeons make sounds by snapping their beaks or hissing.

"Pigeons are dumb.
"They poop on people's heads."
"They smell."
That's what some people say about pigeons.
