Systematics History

Almost universally considered a single species (12, 8, 13, 14, 15), but Cracraft (16), employing a phylogenetic species concept, and del Hoyo and Collar (17) considered C. m. sanguineus to be specifically distinct. Adopting the Tobias et al. (18) criteria (from which scores in parentheses are based) to infer species status, they separated sanguineus as having in males flame-red (versus orange-tinged yellow) upper body (score 3); a black (versus brown) bill (2); mid-brownish-purple (versus dark-edged buffy) crown plumes (2); and darker-shaded, more rufous-tinged tail and outer vanes of wings (not scored); also has marginally longer wings and a shorter tail (not scored).

All contemporary sources have followed Diamond (19) in synonymizing C. m. kuboriensis with C. m. sanguineus, but there remains uncertainty over the taxonomic status of a population in the Western Range, which Beehler and Pratt (15) postulated deserved taxonomic recognition, although they expressed uncertainty as to the geographic boundaries of this form (and indeed the species overall).

Although there is no evidence of hybridization involving this species (8), sympatry between Crested Satinbird and Loria's Satinbird (Cnemophilus loriae) occurs at a few localities (20, 21, 9) and the two could hybridize, whereas cross-breeding with any member of the Paradisaeidae is much more unlikely (8).

Geographic Variation

Two major populations differ principally in their upperparts coloration in males and, less noticeably, in plume color, tail color, and morphometrics. However, their clear separation is to some extent confounded by birds in the Kratke Mts., which appear to be intermediate (8).

Subspecies

Two subspecies recognized.

Systematics History

Cnemophilus sanguineus Iredale, 1948, Australian Zoologist 11:162.—Kumdi, Mt. Hagen District, Papua New Guinea. (22)

The holotype, an adult male collected by Captain N. B. Blood on 24 August 1944, is held at the Australian Museum, Sydney (AM O.37683); three paratypes are held in the same collection: an adult male collected at Moyani, also in Mount Hagen District, by Captain Blood on 23 September 1945 (AM O.38572); and two females, both taken by Blood at Lake Iviva, in the same district, on 7 July 1945 (AM O.38573 and O.38574) (23).

Synonym:
Cnemophilus macgregorii kuboriensis, Mayr and Gilliard, 1954, Bulletin of the American Museum of Natural History 103:361.—Mt. Orata, above Kup [06°06’S, 144°30’E], Kubor Mountains, New Guinea (4). The holotype is an adult male collected at ca. 9,000 ft. on 2 May 1952, by E. Thomas Gilliard, and held at the American Museum of Natural History, New York (AMNH 748584), and two paratypes (also males) both taken by the same collector, at 7,500 ft. on 26 May 1950, are held in the institution (AMNH 705701 and AMNH 705702) (24). Described as being richer and more reddish upperparts, with less copper-red suffusion below, a slightly shorter tail and marginally longer wing. Maintained by Mayr and Greenway (12), but synonymized by Diamond (19) on the basis that all of these characters are variable, minor, and insufficient. Subsequent authors appear to have universally followed Diamond.

Distribution

Mountains of eastern New Guinea (Kaijende Highlands, Mt. Giluwe, and Mt. Hagen region east to at least the Bismarck Mts. and the Kubor Range); also an undiagnosed population in the highlands of central New Guinea (north of Lake Habbema), in Indonesia (15).

Field Identification

Differs from the nominate in its more intense, flame-red (versus orange-yellow) upperparts, blacker bill, brownish-purple crown plumes, and a darker, more rufous tone to the tail and outer wing. Averages longer winged and shorter tailed, but these differences are relatively trivial. Mensural data below from Frith and Beehler (8).

Crested Satinbird (Yellow) Cnemophilus macgregorii macgregorii Scientific name definitions

Systematics History

Cnemophilus macgregorii De Vis, 1890, Annual Report of British New Guinea 1888-89:62.—Mt. Knutsford, 11,000 ft., Owen Stanley Mountains.

The holotype, an adult male collected at the behest of Sir William MacGregor, is held at the Queensland Museum, Brisbane (QM O.19429) (25).

Synonym:
Xanthomelus macgregori Goodwin, 1890, Ibis 6(2):153.—Mt. Musgrave, Owen Stanley Range. The whereabouts of the single specimen, evidently a male which lost its tail when shot, collected by A. P. Goodwin, is unknown. Originally thought to be a regent bowerbird (Xanthomelus = Sericulus) (see 8) and local people in some parts of New Guinea still believe that this species is a bowerbird (2).

Distribution

Southeastern peninsular New Guinea, from at least the Ekuti Divide, south of Wau, to Mt. Knutsford, and north-east Port Moresby, as well as perhaps farther south (see Distribution).

Field Identification

Described under Plumages.

Related Species

Traditionally considered to be a bird-of-paradise (Paradisaeidae) (e.g., by 12, 26, 27, 8), but recent molecular-phylogenetic studies have revealed that the three species of satinbirds comprise a distinct lineage quite distant from the Paradisaeidae, although their precise placement is perhaps still arguable (28, 29, 30). Cracraft and Feinstein (31) were the first authors to cast doubt on the traditional view that satinbirds represent a distinct subfamily (Cnemophilinae) of the Paradisaeidae, despite superficial morphological similarities and polygynous court-display behaviors, and thereafter Barker et al. (32) provided molecular evidence that satinbirds are sister to the Callaeidae (New Zealand wattlebirds), with these two being sister to the Melanocharitidae (berrypeckers and longbills). Jønsson et al. (29) proffered confirmation of these relationships, but other phylogenies (28, 30) have recovered conflicting hypotheses, whilst nevertheless demonstrating the only distant relationship to birds-of-paradise. Crested Satinbird proves, unsurprisingly, to be sister to its sole congeneric, Loria's Satinbird (Cnemophilus loriae), and these two are sister to the only other member of the family, Yellow-breasted Satinbird (Loboparadisea sericea).
