The Plush-crested Jay has a variety of loud vocalizations. One of its most common calls is a ringing "cho-cho-cho" (Ridgely and Tudor 1989). Other vocalizations include: a begging call, directed from one adult to another, jaaay; Eeirrh!; Eeeerrch; a "full-throated mellow ooh!, similar to single note call of Laughing Falcon Herpetotheres cachinnans"; Cleeo; a "rapid-fire, very penetrating creech-creech-creech-creech"; Chock-chock-chock-chock!, "like staccato call of Laughing Falcon"; and a high-pitched eee! eee! (Hardy 1969).
The Plush-crested Jay also imitates other sounds of other birds, and even humans (Sick 1993).
