When she is called for—says the story—the puppets in the four corners begin to coo.
Presently there came the “coo” of a wood-pigeon from in front.
Something between the 'gobble, gobble' of a turkey and the coo of the ring-dove.
He did not “coo” as usual, but stared unsmilingly at the ceiling.
I know all the birds say when they twitter and chirp, caw and coo, gobble and cluck.
