The Pine Grosbeak's call is a soft, fluting and rhythmic whistle. It serves as both a contact call and an alarm call and is often heard before the flock comes into view.
The contact call sounds like a three-part "ti-tu-tu" or "pi-pu-pi" — pure and clear, falling slightly on the last note.
The song is a calm, ringing phrase with fluting whistles and short trills, considerably softer than the Bullfinch's sharp song.
Winter flock call: soft contact notes as 5–30 birds feed together on rowan berries.
The call most resembles that of the Common Crossbill but is longer and softer. Recordings can be found on xeno-canto and the Artportalen (the Swedish species observation system) taxon page.
