<p><b>New page</b></p><div>Beluga calves do not begin life with the adult repertoire fully formed. A longitudinal study of one captive male recorded low-energy broadband pulse trains within his first hour after birth. Rudimentary whistles appeared at about two weeks, whistle production increased substantially in the second month, and mixed tonal–pulsed calls became consistent at about four months. The calf's calls gradually became more stereotyped over months and years.<ref name="development">Vergara, V., and Barrett-Lennard, L. G. (2008).
