Voice - The lively song has been described as up to eight quick notes. The first three to four notes are spaced apart followed by faster notes. It may sound like "seat-seat-seat-sitting-sitting-see", "sweet sweet sweet sweeter-than-sweet", "wheechee weechee wee", or "sweet-sweet-sweet-sweet-setta-see-see-whew". Its call is a clear, soft "chip".
