Order SULIFORMES: Frigatebirds, Gannets, Darters, and Cormorants

We follow the recommendations of Ericson et al. (2006), Hackett et al. (2008), Burleigh et al. (2015), Prum et al. (2015), and Kuhl et al. (2021) in separating this clade of waterbirds from Pelecaniformes. We follow Bock (1994), Clements et al. (2019), and Chesser et al. (2020) in using the name Suliformes. The family sequence follows Clements et al. (2019) and Chesser et al. (2020).

Family FREGATIDAE Degland & Gerbe: Frigatebirds

Fregatinae Degland & Gerbe, 1867: Ornithologie européenne 2(11): 357 – Type genus Fregata La Cépède, 1799.

Genus Fregata La Cépède

Fregata La Cépède, 1799: Tableaux Method. Mamm. Oiseaux: 15 – Type species (by subsequent designation) Pelecanus Aquilus Linnaeus = Fregata aquila (Linnaeus).

Tachypetes Vieillot, 1816: Analyse Nouv. Ornith. Elem.: 63 – Type species (by monotypy) Pelecanus minor Gmelin = Fregata minor (Gmelin).

Atagen G.R. Gray, 1841: List Gen. Birds (2nd edition): 101 – Type species (by original designation) Pelecanus minor Gmelin = Fregata minor (Gmelin).

Parvifregata Mathews, 1920: Birds Australia (Suppl. 1) 1: 64 – Type species (by original designation) Atagen ariel G.R. Gray = Fregata ariel (G.R. Gray).

➤ Fregata minor (Gmelin)
Great Frigatebird

Pelecanus minor Gmelin, 1789: Syst. Nat., 13th edition 1(2): 572. Based on the “Lesser Frigate Pelican” of Latham 1785, Gen. Synop. Birds 3(2): 590 – no locality = Christmas Island, Indian Ocean (fide Lowe 1924, Novit. Zool. 31: 306).

Five subspecies commonly accepted, breeding on islands in the following regions (Dorst & Mougin 1979; del Hoyo et al. 1992; Dickinson 2003): F. m. aldabrensis Mathews, 1914 (west Indian Ocean), F. m. minor (Indian Ocean and South China Sea), F. m. palmerstoni (Pacific Ocean), F. m. ridgwayi Mathews, 1914 (east Pacific Ocean), and F. m. nicolli Mathews, 1914 (Atlantic Ocean). However, Marchant & Higgins (1990) recognised no subspecies. The common name great frigatebird is adopted for this species, following the discussion by Marchant & Higgins (1990).

Fregata minor palmerstoni (Gmelin)
Great Frigatebird

Pelecanus Palmerstoni Gmelin, 1789: Syst. Nat., 13th edition 1(2): 573. Based on the “Palmerston Frigate Pelican” of Latham 1785, Gen. Synop. Birds 3(2): 592 – Palmerston Island, Pacific Ocean.

Fregata minor peninsulae Mathews; Checklist Committee 1990, Checklist Birds N.Z.: 86.

About 18 records from the New Zealand region, the most southerly being Westport (Oliver 1930; Checklist Committee 1953; Edgar 1972b; G. Taylor & Parrish 1991; Medway 2000a; Fryer 2004). The largest flock was eight over the Meyer Islands and Raoul Island, Kermadec Islands / Rangitāhua, Mar. 2016 (Miskelly, Crossland et al. 2017). The earliest record was 1861 (not 1855) – see explanation in Miskelly et al. (2022). Former attribution of New Zealand birds to F. m. peninsulae (Checklist Committee 1990) followed Condon (1975), but that name is a junior synonym of F. m. palmerstoni (see Dorst & Mougin 1979).

➤ Fregata ariel (G.R. Gray)
Lesser Frigatebird

Three subspecies generally accepted (Dorst & Mougin 1979; del Hoyo et al. 1992; Dickinson 2003): F. a. ariel (Indian and Pacific Oceans), F. a. iredalei Mathews, 1914 (west Indian Ocean), and F. a. trinitatis Miranda-Ribeiro, 1919 (Atlantic Ocean), although their distinctiveness has been questioned (Marchant & Higgins 1990).

Fregata ariel ariel (G.R. Gray)
Lesser Frigatebird

Atagen ariel G.R. Gray, 1845: Gen. Birds 3: 669, pl. 185 – no locality = Raine Island, northern Queensland, Australia (fide Mathews 1914, Austral Avian Rec. 2: 121).

Fregata ariel (G.R. Gray); Checklist Committee 1990, Checklist Birds N.Z.: 87.

Breeds on islands off Queensland, New Caledonia, Fiji, and elsewhere in the tropical Pacific Ocean. Straggles to the New Zealand region: about 32 records since 1907, mostly in the north but once south to Otago (Turbott 1952; Checklist Committee 1953; Oliver 1955; Hudson 1963; Lockstone 1967; Edgar 1971b, 1972b; Marchant & Higgins 1990; G. Taylor & Parrish 1991; Powlesland et al. 1992; Pierce 1992; Guest 1992; Medway 2000a; Miskelly, Crossland et al. 2013, 2019) and probably twice to the Chatham Islands (Imber 1994). New Zealand records are considered to be of the closest breeding subspecies (Checklist Committee 1953, 1970; Oliver 1955).

Family SULIDAE Reichenbach: Gannets and Boobies

Sulinae Reichenbach, 1849: Avium Syst. Nat.: 6 – Type genus Sula Brisson, 1760.

Morus and Sula are considered generically distinct (Olson 1985b; van Tets et al. 1988; BOU Records Committee 1991; Friesen & Anderson 1997; J. Nelson 2005).

Genus Morus Vieillot

Morus Vieillot, 1816: Analyse Nouv. Ornith. Elem.: 63 – Type species (by monotypy) Buffon’s “Fou de Bassan” = Pelecanus bassanus Linnaeus = Morus bassanus (Linnaeus).

Moris J.R. Forster, 1817: Synop. Cat. Brit. Birds: 59. Unnecessary nomen novum for Morus Vieillot, 1816.

Breeds on islands off coasts of southern Africa, ranging north in winter and straggling further afield (Dorst & Mougin 1979; C. Robertson & Stephenson 2005). The first New Zealand record was a bird at Cape Kidnappers Dec. 1997–Sep. 2005; it successfully bred with an Australasian gannet and a hybrid chick returned to the colony in 2005 (Medway 2001a; Stephenson 2002, 2003; C. Robertson & Stephenson 2005). Subsequently recorded at Farewell Spit, Dec. 2015 (Miskelly, Crossland et al. 2017).

Australia (breeding on islets off Tasmania and south-east Australia), Philip and Nepean Islands (Norfolk Island group) and New Zealand (Marchant & Higgins 1990; J. Nelson 2005). In New Zealand, breeds on outlying islands from Manawatāwhi / Three Kings Islands to Hauraki Gulf, Bay of Plenty, and Tolaga Bay on the east coast of the North Island; Oaia, Motutara (Sugarloaf Rock at Muriwai Beach), and Karewa / Gannet Islands on the North Island west coast (Wodzicki et al. 1984). Cape Kidnappers (south end of Hawke Bay) and two colonies at Muriwai, opposite Motutara Island, are the only North Island mainland colonies (Wodzicki et al. 1984; B. Greene 2003). In the South Island, colonies are at Waimaru Bay (Pelorus Sound), Arapawa Island, Farewell Spit, The Nuggets, and Little Solander Island (Marchant & Higgins 1990; D. Brown & Wilson 2004). Adult birds range widely in New Zealand seas during winter; juveniles and some adults disperse to coastal waters of Australia, as far west as the Indian Ocean, with vagrants to South Africa and north to New Caledonia (Wodzicki & Stein 1958; Wodzicki 1967; Marchant & Higgins 1990; J. Moore 1999; C. Robertson & Stephenson 2005). Stragglers reach the Chatham Islands (including one breeding record; Imber 1994; Miskelly et al. 2006), Snares / Tini Heke, Auckland Islands / Maukahuka, and Campbell Island / Motu Ihupuku (Kinsky 1969; Miskelly et al. 2001a; Miskelly, Elliott et al. 2020). Midden and Holocene deposits: North, South, and Chatham Islands (Millener 1991).

Genus Sula Brisson

Sula Brisson, 1760: Ornithologie 1: 60; 6: 494 – Type species (by tautonymy) Sula leucogaster Boddaert.

Dysporus Illiger, 1811: Prodromus Syst. Mamm. Avium: 279. Unnecessary nomen novum for Sula Brisson, 1760.

Hemisula Mathews, 1913: Austral Avian Rec. 2: 55 – Type species (by original designation) Sula leucogaster rogersi Mathews.

Parasula Mathews, 1913: Austral Avian Rec. 2: 55 – Type species (by original designation) Sula dactylatra bedouti Mathews.

In his list of New Zealand birds, Gray (1862: 250) included “Sula fiber”, with the following localities: “Enderby’s Island; Lord Howe’s Island?”. We are unable to identify this species, so regard it as a nomen dubium.

➤ Sula sula (Linnaeus)
Red-footed Booby

Pelecanus Sula Linnaeus, 1766, Syst. Nat., 12th edition, 1: 218 – “in Pelago indico” = Barbados, West Indies (fide Grant & Mackworth-Praed 1933, Bull. Brit. Ornith. Club 53: 187).

Sula sula (Linnaeus); Verreaux & Des Murs 1860: Rev. et Mag. de Zool.: 442.

Three subspecies are recognised: S. s. sula breeding in the West Indies, Hispaniola, Puerto Rico, Virgin Islands, Dominica, Grenadines, Belize, Venezuela, on Fernando de Noronha, and possibly Ascension Island; S. s. rubripes breeding on many Indian Ocean and Pacific Ocean islands; S. s. websteri breeding on Revillagigedo Islands off Mexico, Cocos Island off Costa Rica, and Galápagos Islands (Dorst & Mougin 1979). Four records from New Zealand (Miskelly, Crossland et al. 2021). The first birds of this species from New Zealand (two at the Kermadec Islands / Rangitāhua in Mar.–Apr. 2016; Miskelly, Crossland et al. 2017) were not identified to subspecies.

F. Hutton (1871: 49) listed “Dysporus piscator L. – red-legged gannet”, but the taxon Pelecanus piscator Linnaeus, 1758 is a nomen dubium. Therefore, Hutton’s citation cannot be assigned to any subspecies of Sula sula.

Sula sula rubripes Gould
Indo-Pacific Red-footed Booby

Sula rubripes Gould, 1838: Synop. Birds Australia 4, App.: 7 – “New South Wales” = Raine Island, northern Queensland (fide Mathews 1915, Birds Australia 4: 210).

Sula nicolli Grant & Mackworth-Praed, 1933: Bull. Brit. Ornith. Club 53: 118 – Gloriosa Island, Indian Ocean.

Sula sula rubripes Gould; del Hoyo et al. 1992: Handb. Birds World 1: 325.

A bird considered to be of this subspecies was found dead on Pakatoa Island, Hauraki Gulf, in May 2017 (Miskelly, Crossland et al. 2021; Auckland Museum specimen LB15822).

Sula sula websteri Rothschild
Eastern Pacific Red-footed Booby

Sula websteri Rothschild, 1898: Bull. Brit. Ornith. Club 54: 52 – “Clarion Island, Galapagos and the neighbouring seas” = Clarion Island, Revillagigedo Islands (fide Dorst & Mougin 1979, in Peters, Check-list Birds World 1 (2nd edition): 186).

Sula sula websteri Rothschild; del Hoyo et al. 1992: Handb. Birds World 1: 325.

A bird considered to be of this subspecies was present at the Muriwai gannet colony, west Auckland, for 5 weeks in early 2017 (Miskelly, Crossland et al. 2019).

➤ Sula leucogaster (Boddaert)
Brown Booby

Pelecanus Leucogaster Boddaert, 1783: Tables des Planches Enluminéez d’Histoire Naturelle de M. d’Aubenton: 57, pl. 973 – Cayenne, South America.

Breeds on tropical islands of the Indian, Pacific, and Atlantic Oceans, and the Caribbean Sea. Four subspecies; three outside New Zealand region (Dorst & Mougin 1979, Carboneras 1992b): breeding on Atlantic Ocean and Caribbean islands (S. l. leucogaster) and on eastern Pacific islands (S. l. brewsteri Goss, 1888, and S. l. etesiaca Thayer & Bangs, 1905). All subspecies considered doubtfully distinct by some authors (e.g. Marchant & Higgins 1990).

Sula leucogaster plotus (J.R. Forster)
Brown Booby

Pelecanus Plotus J.R. Forster, 1844: in Lichtenstein Descrip. Animalium: 278 – near New Caledonia.

Sula leucogaster plotus (Forster); Checklist Committee 1953, Checklist N.Z. Birds: 28.

Breeds on tropical islands in the Pacific and Indian Oceans, also the Red Sea and Gulf of Aden (Dorst & Mougin 1979). Reaches New Zealand waters probably every year (e.g. Powlesland & Powlesland 1993; Veitch et al. 2004; Miskelly, Crossland et al. 2017), rarely south to about 45°S (Pierce 1969). Sometimes these vagrants reside in an area for several months (e.g. Gaze 1975; Guest 1992; G. Taylor & Parrish 1992, 1994a) and may associate with gannets (e.g. Stein 1952; Hawkins et al. 1992; Hawkins & Cook 1994; Miskelly, Crossland et al. 2017). A banded juvenile from Johnston Atoll was collected offshore from Okarito in 1986 (NMNZ OR.023569).

➤ Sula dactylatra Lesson
Masked Booby

Sula dactylatra Lesson, 1831: Traité d’Ornith. 8: 601 – Ascension Island, Atlantic Ocean.

Also known as the blue-faced booby. Four subspecies; all but one (S. d. tasmani) outside the New Zealand region (Dorst & Mougin 1979; Pitman & Jehl 1998): Atlantic Ocean and Caribbean islands (S. d. dactylatra), Indian Ocean and Arabian Sea islands (S. d. melanops Heuglin, 1859), and islands in the eastern Indian Ocean, the Banda and Coral Seas and much of the Pacific Ocean (S. d. personata Gould, 1846). A fifth race, from the eastern Indian Ocean, – S. d. bedouti Mathews, 1913 – is recognised by some authors (e.g. Marchant & Higgins 1990; R. O’Brien & Davies 1990; Dickinson 2003). The Nazca booby (Sula granti Rothschild, 1902), breeding on some eastern Pacific islands, was formerly regarded as a race of S. dactylatra (Pitman & Jehl 1998). Masked boobies straggle south to northern New Zealand, but their subspecific identity or identities have not been determined: Karewa / Gannet Island, 1883; west of North Cape (Otou), 1964; two, Firth of Thames, 1977–78 (Powlesland & Pickard 1992); near Hamilton, Jul. 1983 (J. Moore 1985a); beach-wrecked near Dargaville, May 1988 (Powlesland & Pickard 1992); Paraparaumu Beach, Sep. 1995 (NMNZ OR.025810); Nine Mile Beach, Buller (Scofield 2008). Recorded as Holocene remains at the Chatham Islands (Millener 1991).

Sula dactylatra tasmani van Tets, Meredith, Fullagar & Davidson; McAllan, Curtis, Hutton & Cooper 2004, Australian Field Ornithology 21(Suppl.): 6.

Local subspecies S. d. tasmani breeds on islands in the Lord Howe, Norfolk Island, and Kermadec Islands / Rangitāhua groups (R. O’Brien & Davies 1990). This subspecies was first described from Holocene material as an extinct species (van Tets et al. 1988) but is now considered to be conspecific with the extant masked booby (Holdaway & Anderson 2001; Holdaway et al. 2001; Worthy & Holdaway 2002; McAllan et al. 2004; Priddel et al. 2005). Ranges mainly north to the east coast of Australia, New Caledonia, Vanuatu (Marchant & Higgins 1990; Priddel et al. 2005; Anon. 2006a), Fiji (Anon. 2004a), and Tonga (J. Moore 1999). Sometimes called the Tasman booby (e.g. van Tets et al. 1988).

Australia and New Guinea. Four or five stragglers recorded in New Zealand: possibly seen at Lake Ohau in “summer” 1862; one dead Hokitika, Jan. 1874 (Buller 1875a; Oliver 1955; van Tets & Scarlett 1972). Also live birds: Waiharara, Northland, Dec. 1992 (Medway 2000a); Lake Daniell, Nelson, Nov. 2003 (Scofield 2005a); and Wellington Harbour, Dec. 2003 (Medway 2004b). This race is sometimes considered to be a full species (Marchant & Higgins 1990; del Hoyo et al. 1992).

Family PHALACROCORACIDAE Reichenbach: Cormorants and Shags | Kawau

Phalacrocoracidae Reichenbach, 1849: Avium Syst. Nat.: 6 – Type genus Phalacrocorax Brisson, 1760.

We follow the classification system proposed by Kennedy & Spencer (2014). This includes placement of little shag in the genus Microcarbo, and spotted shag and Pitt Island shag in the genus Phalacrocorax.

Genus Microcarbo Bonaparte

Microcarbo Bonaparte, 1855: Consp. Av. 2: 177. Nomen nudum.

Microcarbo Bonaparte, 1856: Compt. Rend. Séa. Acad. Sci., Paris 43: 577 – Type species (by original designation) Pelecanus pygmaeus Pallas = Microcarbo pygmaeus (Pallas).

Haliëtor Heine, 1860: Journ. für Ornith. 8: 202 – Type species (by original designation) Pelecanus pygmaeus Pallas = Microcarbo pygmaeus (Pallas).

➤ Microcarbo melanoleucos (Vieillot)
Little Pied Cormorant

Three subspecies: M. m. melanoleucos in south-east Asia, New Guinea, Australia, and some western Pacific Islands, M. m. brevicauda (Mayr, 1931) on Rennell Island, Solomon Islands, and M. m. brevirostris in New Zealand (Dorst & Mougin 1979; Marchant & Higgins 1990). Some authors consider M. m. brevirostris to be the same taxon as M. m. melanoleucos (e.g. Dowding & Taylor 1987; M. Taylor 1987) but others regard it as a distinct species (see Marchant & Higgins 1990; del Hoyo et al. 1992). One record from Chatham Island in 1988–89 of uncertain subspecies (Miskelly et al. 2006).

Australia, south-east Asia, New Guinea, and some western Pacific Islands (Marchant & Higgins 1990). Bred on Campbell Island / Motu Ihupuku 1967–69 (Kinsky 1969; Marchant & Higgins 1990; del Hoyo et al. 1992). At least seven pied birds on Snares Islands / Tini Heke in 1976–77 were considered to have originated in Australia (Sagar 1977). Several other records from Snares Islands / Tini Heke were also pied birds: 1975 and sightings 1982–85 (Horning 1976; Miskelly et al. 2001a; NMNZ OR.018703). Vagrant little shags on Norfolk Island in 1978, 1979, and 1996–97 were apparently pied (J. Moore 1981, 1999; Schodde et al. 1983), so most likely from Australia. Occasional immigration to mainland New Zealand from Australia has been suggested by several authors (Buller 1887–88; Dowding & Taylor 1987; Marchant & Higgins 1990; Secker 1994).

Breeds from North Cape (Otou) to Stewart Island / Rakiura and on nearby offshore islands. Vagrant to Snares Islands / Tini Heke in the 1960s, where it may have bred (Warham 1967; Warham & Keeley 1969). Apparently this subspecies also reached the Auckland Islands / Maukahuka in 1942, and Campbell Island / Motu Ihupuku in 1958 (Bailey & Sorensen 1962; Miskelly, Elliott et al. 2020). A dimorphic subspecies with some intermediate variants; the relative scarcity of the latter suggests that the white-breasted phase may be maintained by occasional immigration of Ph. m. melanoleucos from Australia (Dowding & Taylor 1987). In Holocene deposits and middens in North, South, and Stewart Islands (e.g. Horn 1983; Worthy 1998c, 1998d).

➤ Phalacrocorax carbo (Linnaeus)
Great Cormorant

Pelecanus carbo Linnaeus, 1758: Syst. Nat., 10th edition 1: 133 – Europe, restricted to the “rock nesting form of the north Atlantic Ocean” (fide Hartert 1920, Vögel Pal. Fauna: 1387).

Widespread. Six subspecies widely accepted: Europe and North America, Ph. c. carbo; Europe and Asia, Ph. c. sinensis (Blumenbach, 1798); Japan, Ph. c. hanedae Kuroda, 1925; north-west Africa, Ph. c. maroccanus Hartert, 1906; Africa, Ph. c. lucidus (Lichtenstein, 1823); and Australasia, Ph. c. novaehollandiae (see Dorst & Mougin 1979; del Hoyo et al. 1992; Dickinson 2003). An additional race from north-east Africa (Ph. c. lugubris Rüppell, 1845) is sometimes accepted (Dickinson 2003). The form in Australasia (Ph. c. novaehollandiae) is sometimes considered to be a full species (e.g. Buller 1905–06; Siegel-Causey 1988; del Hoyo et al. 1992) with one subspecies in Australia, Ph. n. novaehollandiae – not Ph. n. carboides Gould, 1838 contra Marchant & Higgins (1990: 810) and del Hoyo et al. (1992) – and another in New Zealand, Ph. n. steadi (Mathews & Iredale, 1913) (Dorst & Mougin 1979). However, Pelecanus major Ellman, 1861 is a senior synonym for the New Zealand form. The African race Ph. c. lucidus is also sometimes considered to be a full species (del Hoyo et al. 1992). The six widely used races are accepted here, pending a full taxonomic review of the group.

Inhabits coastal waters and breeds only from near Oamaru south to The Sisters, Catlins coast (Rawlence et al. 2016). Ranges north to Banks Peninsula (Crossland 2021). Midden and Late Pleistocene or Holocene bone deposits, Cape Wanbrow, Otago, and Marfells Beach, Marlborough (Worthy 1998d; Worthy & Grant-Mackie 2003; Rawlence, Till et al. 2017).

The dimorphic Leucocarbo shags of Otago, Southland, and Stewart Island were considered a single species (Stewart Island shag L. chalconotus) until Rawlence et al. (2016) demonstrated that the Otago population was sister to the monomorphic Chatham Island shag (L. onslowi), meaning that either all three populations were conspecific, or that they should all be considered full species. We follow Rawlence et al. (2016) in separating the northern and southern populations of Stewart Island shag (sensu Checklist Committee 2010) as full species. The type specimen for L. chalconotus was from Otago (G.R. Gray 1845), and so this name is retained for the larger northern species, with Otago shag as the recommended English name.
