Unison call: The unison call is uttered by pairs of cranes, usually standing close to each other. It reinforces the bond between pairs but can also be used by a pair to scare off potential predators.

Guard call: When a big group of sandhill cranes is sleeping or when they have paired up in breeding grounds, at least one crane is standing guard against predators. This is the call they make when they see or hear something threatening.
