Belugas are extremely vocal

Since many species of whales and dolphins make a wide range of sounds for social communication as well as echolocation, they are renowned for their intellect and loquacity. Belugas are thought to possess very advanced echolocation and hearing abilities, and the vocal range of these animals has led to parallels to songbirds. The term "sea canary" is another, much nicer-sounding moniker belugas have acquired for themselves, and it originates from the animal's rich and diverse vocalizations

Belugas occasionally make boisterous noises that may be heard above the water or even through the boat hulls. There are 34 different cries made by belugas, which can include varied whistles, trills, bleats, chirps, mews, and even bell-like tones, in addition to echolocation clicks, according to a 2015 study of a population in Alaska's Beaufort Sea. The noises are thought to serve as a sort of communication amongst whales in addition to being utilized for echolocation in dark seas. Exchanges between mothers and calves resemble the sound of a finger gliding across a plastic comb.
