Calls 231, 291, 981 unclear (per Gary Allport). Sonagrams appear similar with ascending first part, and less modulated with the second, but variable. From photos, 231 is male grey-headed type without supercilium, 291 similar but with clear thin white supercilium behind eye, 981 grey-headed without real supercilium but small white marks in front and behind eye
