TYTONIDAE (5 species)

Tyto novaehollandiae Masked Owl
NOTE:T. n. castanops, the Tasmanian form, sometimes treated as full species (Sibley and Monroe 1990).
T. n. castanops Int in 1920s (10+ prs) Lord Howe I. (May have been some T. n. novaehollandiae introduced also, McAllan et al 2004; genetic studies confirm presence of genes from mainland Australia subspecies T. n. novaehollandiae, thus Lord Howe I birds are likely to be of of mixed provenance, Hogan et al 2013).

T. delicatula Eastern Barn Owl
NOTE: Recent studies (see Christidis and Boles 2008) suggest that Barn Owls of southern Asia, Australia, and the southwest Pacific are separable at the species level, as are those of the Americas; the specific epithet for the former is delicatula, rather than javanica, which is a subspecies of Old World Tyto alba (see Boyd), and for the latter furcata, which is the oldest name available (Christidis and Boles 2008).
The subspecies bellonae is not recognized by Mayr and Diamond (2001); any or all of bellonae, interposita, lifuensis, and lulu are doubtfully separable. Dutson (2011) uses crassirostris for birds endemic to Tanga, New Ireland, and includes all Solomon Is birds in delicatula.
Worthy (BIRDING-NZ) believes that Barn Owls have colonized all islands that they occupy east of the Solomons (Fiji, Niue etc) during the last 3000 years (Niue 2100 years, Samoa 1200 years), and were not there before humans came to these islands and introduced Pacific Rat (kiore). Worthy believes also that this rapid spread would be relatively unlikely if only one owl ever dispersed out side its existing range at one time so it seems likely they have a propensity to colonize in small groups.

Ninox boobook Southern Boobook
NOTE: Christidis and Boles (2008), in combining novaeseelandiae and boobook, pointed out that findings of Norman et al (1998) have been mis-interpreted in the literature and did not in fact provide evidence for species status of the two forms. However there is growing consensus that birds from Tasmania (leucopsis, New Zealand (novaeseelandiae), and Norfolk Island (undulata comprise a separate species (IOC Checklist; David James, post to BIRDING-AUS 18 Jun 2013), as shown below.

ALCEDINIDAE (3 species)

Distinctness of this family from Halcyonidae was discussed by Christidis and Boles (1994), who noted also that Halcyonidae has precedence over Dacelonidae. Following Fry and Fry (1999), Cerylidae has equivalent status. Some authors (eg Boyd) treat the three families as subfamilies of Halcyonidae.

Ceyx lepidus Dwarf Kingfisher
NOTE: Fry and Fry (1999) included this taxon in Alcedo "partly out of convenience", noting that it has characters of both genera. Recent studies indicate that Alcedo thus constituted is paraphyletic, and pusilla, often included in Alcedo, belongs in Ceyx (see Christidis and Boles 2008). Fry and Fry (1999) included pallidus in meeki. Mayr and Diamond (2001) considered meeki (including pallidus) quite distinct.
C. l. pallidus Res Solomon Is (Bougainville, Buka).
C. l. meeki Res Solomon Is (Choiseul, Santa Isabel).

HALCYONIDAE (17 species)

Fry and Fry (1999) included "Pacific flatbills" Todiramphus in Halcyon, a course followed by Pratt et al (1987) and Mayr and Diamond (2001). However Christidis and Boles (1994, 2008) considered Australasian species sometimes placed in Halcyon to be distinct at the generic level from African and Asian members of the genus, based on a broad range of evidence. Christidis and Boles (1994, 2008) used Todiramphus for these Australasian species, although others, while recognizing Todiramphus, have limited its use to birds of certain Pacific islands, such as T. tutus).

T. saurophagus Beach Kingfisher
NOTE:Mayr and Diamond (2001) suggest that this species and T. chloris arose in different geographic areas of Northern Melanesia and have not yet become sympatric, although there may be some introgression in the northern Bismarcks.
T. s. saurophagus Res Solomon Is e to Makira and Santa Ana, incl Green Is and Nuguria (Tarburton 2006), Takuu and Tulun (Hadden 2004b), but not Rennell (Dutson 2011).

T. chloris White-collared Kingfisher
NOTE: Species limits between this species, T. sanctus, and T. tutus are unsettled. Mayr and Diamond (2001) note that T. sanctus and T. chloris are closely related and "seem to have spread in several waves". T. sanctus is generally smaller, and occupies more open habitats and smaller perches than T. chloris where they occur together in Northern Melanesia (Mayr and Diamond 2001). Pratt et al (1987) assigned the rusty-bellied taxa of Fiji and Futuna (vitiensis, eximius, and regina) to T. sanctus (contra Mayr and Diamond 2001), based on their resemblance to New Caledonia birds and vocalizations, and the eastern Fijian, Tongan, and Samoan taxa marinus, sacer, manuae and pealei to T. tutus, based on generally smaller size than other chloris taxa, and their resemblance in plumage and vocalizations to T. tutus. Fry and Fry (1999), while indicating that the assignments of Pratt et al (1987) may be correct, retained these groups of taxa in T. chloris. A sighting of 2 birds on Nauru Apr-Jul 1961 may be this taxon or T. sanctus (Buden 2008).
T. c. teraokai Res Palau.
T. c. owstoni Res Mariana Is (Sarigan, Alamagan, Pagan, Agrigan, Asuncion).

T. cinnamominus Micronesian Kingfisher
NOTE: This species is a member of the T. chloris group (Pratt et al 1987). Pratt and Etpison (2008) consider this group of 3 subspecies to be separate species, using Rusty-capped Kingfisher for the English name of pelewensis.
T. c. pelewensis Res Palau.
T. c. reichenbachii Res Caroline Is (Pohnpei).
T. c. cinnamominus Formerly res Mariana Is (Guam, now extirp, Reichel and Glass 1991).

T. sanctus Sacred Kingfisher
NOTE: Fry and Fry (1999) included T. recurvirostris in T. sanctus, but it is rather distinct. Subspecies norfolkiensis and adamsi are often included in vagans; while adamsi is indeed rather similar to vagans, norfolkiensis, along with birds from Kermadec Is, is rather dissimilar (HANZAB).
T. s. sanctus Res? Solomon Is (has bred Guadalcanal, Three Sisters, other islands, Mayr and Diamond 2001). Mostly vis Mar-Sep Solomon Is from Australia (HANZAB, Hadden 2004a, 2004b) east to Makira but not Rennell or Temotu, but incl Green Is, Tulun, Takuu (Hadden 2004b), Nissan (Tarburton 2006).

T. s. eximius Res Fiji (Kadavu, Ono, Vanua Kula).
T. s. regina Res Wallis and Futuna (Futuna, Alofi, Thibault et al 2015).

T. recurvirostris Flat-billed Kingfisher
NOTE: Sometimes considered conspecific with T. sanctus, but the rusty-bellied taxa found in Fiji (vitiensis, eximius, and regina) are much more similar to T. sanctus than is T. recurvirostris (Pratt et al 1987).
Res Samoa (Savaii, Upolu).

T. tutus Pacific (Chattering) Kingfisher
NOTE: This species and the next five belong to the T. chloris group (Pratt et al 1987); they were considered to constitute the Todiramphus allospecies group by Mayr and Diamond (2001), a more limited position than that taken by Christidis and Boles (1994, 2008). Holyoak (1980) mentions a kingfisher of unknown affinities on Rarotonga until about 1940; it seems likely on geographic grounds to have been part of the T. tutus group.
T. t. tutus Res Society Is (Bora Bora, Maupiti, Raiatea, Huahine, Tahaa, Tupai, Tahiti).
T. t. atiu Res Cook Is (Atiu).
T. t. mauke Res Cook Is (Mauke).

NOTE: This species and the next 4 are sometimes included within T. tutus.
T. v. veneratus Res Society Is (Tahiti).
T. v. youngi Res Society Is (Moorea).

T. ruficollaris Mangaia Kingfisher
NOTE: Treated as a subspecies of T. tutus by Fry and Fry (1999), who noted that it could as easily be included in H. sancta.
Res Cook Is 400-700 inds (Mangaia).

T. gambieri Gambier Kingfisher
NOTE: Fry and Fry (1999), while noting the isolation of this taxon from similar taxa, tentatively included it in T. tutus because of its resemblance to the latter. DuPont (1975) considered this a "doubtful species", questioning the Mangareva type locality and speculating that the single known specimen may have come from Micronesia.
Extinct. Res formerly Gambier Is (Mangareva).

T. gertrudae Niau Kingfisher
NOTE: Although sometimes treated with gambieri as subspecies of "Tuamotu Kingfisher", the two are separated by 1250 km with no evidence that kingfishers occurred on the scores of intervening islands (Fry and Fry 1999).
Res Tuamotu Is (Niau).

T. godeffroyi Marquesas Kingfisher
