| 6.1 GREY-HEADED ALBATROSS Thalassarche chrysostoma [Albatros à tête grise] W 192cm. From 6.2 by greyer head, more black to leading edge of underwing and yellow lower ridge to bill. Rather similar to 6.4, but note that yellow starts narrowly at upper ridge of bill. Juv. with dark underwings like Juv. 6.3, but differs by white, not grey head. Offshore and open ocean. Mid-high, nasal bleating. Breeds NZ 7. R | |
| 6.2 YELLOW-NOSED ALBATROSS9 Thalassarche chlororhynchos [Albatros à nez jaune] W 200cm. Shown are Nom. (a, with grey head) and ssp bassi/carteri (b, with white head). From 6.4 by lack of black mark in axillaries. Lack of yellow line along lower mandible in Ad. diagnostic. Note narrow black leading edge of underwings. Inshore and offshore. High, scratchy bleating or raspy wuc-wuc-wuc. Off NZ. | |
| 6.3 BLACK-BROWED ALBATROSS10 Thalassarche melanophris [Albatros à sourcils noirs] W 230cm. Shown are dark-eyed Nom. (a) and pale-eyed ssp impavida (b). b might show slightly more extensive black than a to underwings (not shown). Yellow bill and lack of grey to head diagnostic in Ad. Juv. with black bill and dark underwings shows complete or partial grey breast-band. Breeds on cliff ridges and ledges. Offshore and pelagic. Breeds NZ 5,7,8. | |
| 6.4 SHY (or NZWhite-capped) ALBATROSS11 Thalassarche cauta [Albatros à cape blanche] W 234cm. 4 ssps in the area: Nom. (NZTasmanian Albatross not shown; resembles b), steadi (a, NZNew Zealand White-capped Albatross), salvini (b, NZSalvin’s Albatross) and eremita (c NZChatham Island Albatross). a, b and c breed in the area. Black diagnostic mark in axillaries, where black leading edge of wings meets body. Colour of bill and saturation of grey or brown to head differ among ssps, but all ssps show narrow black leading edge to underwings. Breeds on level places in rocky, broken areas. Offshore. High, drawn-out, slightly shivering, lowing or toneless, nasal twittering and braying. Breeds NZ 4–6,8. R | |
| 6.5 BULLER’S ALBATROSS Thalassarche bulleri12 [Albatros de Buller] W 209cm. Two ssps: Nom. (a, Northern Buller’s Albatross): note broad yellow base to yellow line along culmen; and ssp platei (b, NZSouthern Buller’s Albatross, with a greyer forehead). b differs from a mainly in timing of breeding (a breeds 2–3 months later than b). Bill of b is supposed to be slightly broader, black eyebrow longer between eye and base of bill and forehead and crown silvery grey, not silvery white like a, but all these features may vary. From Ad. 6.1 also by clear-cut black leading edge to underwings. Breeds on slopes, ridges and tops of rocky slopes with sparse, low vegetation. Inshore, offshore and open ocean. Braying notes and drawn-out lowing. a breeds NZ 4,5,12; b breeds NZ 4,11. R |
