An estimated flock of 400 visit the Salton Sea each winter. "Sandhill Cranes give loud, rattling bugle calls, each lasting a couple of seconds and often strung together. They can be heard up to 2.5 miles away and are given on the ground as well as in flight, when the flock may be very high and hard to see. They also give moans, hisses, gooselike honks, and snoring sounds. Chicks give trills and purrs." (the Cornell lab of Ornithology)
