Song: Melancholy, fluting, with short phrases repeated with pauses — a powerful, wistful soundscape in the mountain setting. Phonetically roughly “klotjiu-klotjiu-klotjiu” with a varying number of beats and pitch; it likes to sing from boulders, cliff edges and tall willow bushes.
Call: a hard, recurring “tsack-tsack” — like the Blackbird's but drier and more metallic; heard on disturbance and often the first thing one hears of the species.
Alarm: repeated series of “tack-tack-tack” when a predator or person approaches the nest.
