FUN FACTS from Wikipedia: 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.
