Оглавление8 Prions, Fulmars & Petrels
Note that most Prions show distinct M on wings, but cf. 9.3–4, 9.7–8, 10.1–2, 10.5–8, 11.1, 11.4–5, 12.3 and 14.2.8.1 BROAD-BILLED PRION Pachyptila vittata [Prion de Forster] W 62cm. Seemingly large-headed. Bill larger than the other 5 prions and coloured black (not grey like 8.2). Note steep forehead. Breeds in burrows or in caves and crevices in cliffs. Offshore and open ocean. Short, very low, rhythmic croaking. Breeds NZ 4,5. | |
8.2 SALVIN’S PRION Pachyptila salvini [Prion de Salvin] W 57cm. Separation from 8.1 and 8.3 probably impossible at sea. In the hand shows comb-like lamellae at base of closed bill. Bill grey. Inshore and offshore. Hoarse, rather excited croaking at different pitch. NZ seas. | |
8.3 ANTARCTIC PRION Pachyptila desolata [Prion de la Désolation] W 63cm. Smaller and bluer bill than 8.1 and – though collar more distinct – not safely separable from 8.2. Breeds in burrows and rock crevices; feeds offshore and in open ocean. Low, hoarse and falsetto croaking (not unlike statics on radio). Breeds NZ 6,8. | |
8.4 SLENDER- (or NZThin-)BILLED PRION Pachyptila belcheri [Prion de Belcher] W 56cm. The M on wings less distinct than 8.1–8.3, especially in worn plumage (a). Note small, narrow bill and extensive, distinct white eyebrow, giving pale-faced expression. Inshore, offshore and open ocean. NZ seas. | |
8.5 FAIRY PRION Pachyptila turtur [Prion colombe] W 56cm. Note indistinct facial pattern and narrow M on wings. At sea not safely separable from 8.6. Breeds in burrows or in rock crevices and caves. Feeds offshore and in open ocean. High, excited croaking. Breeds NZ 4,5,8. | |
8.6 FULMAR PRION13 Pachyptila crassirostris [Prion à bec épais] W 60cm. Difficult to separate at sea from smaller-billed 8.5 with similar pale face pattern; best distinction said to be its ‘looping’ flight. Breeds in crevices and in tunnels in cliffs. At sea, inshore and offshore. Low, hoarse, at times bouncing croaking. Breeds NZ 4–6,9. | |
8.7 ANTARCTIC PETREL Thalassoica antarctica [Pétrel antarctique] W 105cm. Note characteristic pattern of upperparts with contrasting white secondaries and tail. Inshore and offshore. Low, hoarse croaks. Breeds NZ 8. R | |
8.8 NORTHERN FULMAR Fulmarus glacialis [Fulmar boréal] W 107cm. Pale morph (b) more blotchy, less solid pearl-grey above and its dark morph (b, only morph yet seen near Hawaii) is darker than the Atlantic ssp glacialis (which does not occur in the area). Offshore. Off Ha. R | |
8.9 SOUTHERN (or NZAntarctic) FULMAR Fulmarus glacialoides [Fulmar argenté] W 118cm. Note diagnostic contrasting wing pattern with white flash on outer wings more contrastingly patterned above than 8.4. From gulls by gliding flight on stiff wings. Offshore and open ocean. High, hoarse, subdued shrieks. Breeds NZ 8. |
