Diademhäher
Like other jays, the Steller's jay has numerous and variable vocalizations. One common call is a harsh "SHACK-Sheck-sheck-sheck-sheck-sheck" series; another "skreeka! skreeka!" call sounds almost exactly like an old-fashioned pump handle; yet another is a soft, breathy "hoodle hoodle" whistle. Its alarm call is a harsh, nasal "wah". Some calls are sex-specific: females produce a rattling sound, while males make a high-pitched "gleep gleep".
