Captive Studies Reveal Extensive Vocal Range in the Sacred Kingfisher

Abstract

While rehabilitating Sacred Kingfishers Halcyon sancta following injury, we recorded many vocalisations previously undescribed and possibly unsuspected. This paper describes eight new calls in two groups: loud calls given primarily during the day, and softer calls produced mainly during the night in a social context. It is suggested that these calls reflect a much greater level of vocal behaviour for this species than previously expected.
