If a rooster spots danger, he sends out a shrill cry. The other roosters echo the cry. Thereupon, the whole flock will often start up a loud, incessant, drum-beating chorus with all members facing the direction of the first alarm, or scattering for cover in the opposite direction. When it looks safe again, an "all clear?" query goes out from the rooster, first one, followed by the others, in their various new places. Eventually the bird who first raised the alarm sends up the "all clear" crow, and a series of locator crows confirms where every other rooster and his sub-flock are at this point.
