PRYS-JONES Introduction as a taxon—it was omitted entirely in Peters (1934)—has not been The Crested Fireback Lophura ignita is a Sundaic forest species with critically examined or challenged. populations in Peninsular Malaysia, Sumatra and Borneo. The usual The reasons for this can be traced to the comprehensive review taxonomic treatment in recent checklists (Dickinson 2003, Clements of macartneyi—building on the work of Büttikofer (1895)— 2007), monographs (Delacour 1951, 1977, Johnsgard 1999, provided by Delacour (1949). This study made some crucial McGowan 1994, Madge & McGowan 2002, Hennache & Ottaviani clarifications and advances in the taxonomy of Lophura ignita and 2005), regional avifaunas (van Marle & Voous 1988, Mann 2008) and L. rufa, covering the history of the ‘many names’ (macartneyi, the international Red List (BirdLife International 2001) has been to sumatrana, delacouri and albipennis) for Sumatran birds associated accept the existence of four subspecies: L. i. rufa (Raffles, 1822) in with these taxa and, through careful analysis of descriptions, the Thai-Malay Peninsula and most of Sumatra except the far south- pinning those names to particular museum specimens. In east; L. i. macartneyi (Temminck, 1813) in the far south-east of documenting eight male study skins at the Rijksmuseum van Sumatra; L. i. ignita (Shaw, 1798—for the date of which see Natuurlijke Historie (now Naturalis) at Leiden, Netherlands, Dickinson et al. 2006) on the Sumatran island of Bangka and in Delacour (1949) developed the view that the considerations of Borneo except the north; and L. i. nobilis (P. L. Sclater, 1863) in previous authors (Ghigi 1926, Kloss 1931, Beebe 1936) were ‘based northern Borneo. on the conception that ignita… and rufa are two different species’ Of these subspecies, nobilis is clearly only slightly different from and that ‘a more modern idea of systematics’ is rather that ‘the ignita, such that Mann (2008) was unable to provide an indication Crested Firebacks constitute but one species with four subspecies of where they replace each other, while macartneyi shows (ignita, nobilis, macartneyi, rufa), macartneyi serving as a link and a characters that suggest it to be ‘intermediate between ignita and transition’. He therefore preferred ‘to consider macartneyi as a rufa’ (Delacour 1951, 1977). However, such are the differences subspecies inhabiting the south-eastern part of [Sumatra], that is between ignita and rufa that it has been proposed they be variable in colour and still in the course of evolution’. reinstated (following, e.g., Kloss 1931, Peters 1934, Beebe 1936, In further pursuit of this interpretation, two years later Delacour Ghigi 1968) as separate species: male rufa, compared to (‘vs’) male (1951) accounted for the various names and appearances of birds ignita, has (1) dark blue belly (continuous with breast) with fine in south-east Sumatra by calling them ‘phases’ (the term ‘morph’ white flank-streaks vs a chestnut belly and flanks, (2) white vs buffy- was only coined four years later: Huxley 1955). The ‘phase to which rufous central tail feathers, and (3) red vs greenish-white legs (del the type [specimen 1 in Table 1] belongs’ (i.e. the form macartneyi) Hoyo & Collar 2014), plus (4) red-tinged blue vs all-blue lobes on has buff central rectrices and is either (a) like ignita (dark blue breast, the face-wattles fide Delacour (1949, 1951), although not evident rufous belly) but heavier in shape and with generally paler rufous in internet photographs; the female differs by its (5) rich rufous vs colours or (b) with breast and belly dark blue and flanks with rufous blackish wings and tail (del Hoyo & Collar 2014). patches. The phase delacouri ‘has plain rufous sides but the central This arrangement, however, hinges on a clearer understanding rectrices are mostly white’. The phase sumatrana has the belly dark of the status of macartneyi. An illustration (McGowan 1994) blue, rufous or mixed, flank feathers black-based and rufous-tipped, suggests that this is itself a highly distinctive taxon, although the the rufous varying in size and tone and with or without a black accompanying text reveals a far less clear-cut situation: ‘race border, and central rectrices white, sometimes washed buff usually macartneyi very variable, with several apparently co-existing colour near the base and with variable amounts of black. The phase morphs described, based mainly on amount of rufous on plumage’ albipennis replaces the rufous of the flank markings of blue-bellied (McGowan 1994). In spite of this and other passing comments in birds with white. Delacour (1951) judged that the first three phases the recent literature concerning the variability of macartneyi (e.g. co-occur, while the fourth is found close to the range of and is van Marle & Voous 1987, Hennache & Ottaviani 2005), its validity ‘intermediate’ with rufa. Forktail 30 short notes.p65 135 11/26/2014, 11:51 AM 136 SHORT NOTES Forktail 30 (2014) A still more modern idea of systematics would, surely, reject doubts on the matter. Alain Hennache (in litt. 2013) reports that the notion that a subspecies can be based on a population which among living captive specimens he ‘never saw one looking like the is so variable that it divides into four phases, two of which other’ and is convinced of their hybrid origin. Ludo Pinceel (in litt. themselves consist of seemingly almost infinite permutations. Every 2013) and Heiner Jacken (in litt. 2013) concur, the latter reporting living taxon is inevitably ‘in the course of evolution’, but the notion that ‘Today many breeders try to “stabilise” the macartneyi form by that evidence of this can be provided by such an array of plumage pairing continuously macartneyi to each other, thus creating a new variation is not normally one that finds any modern expression. “species” called “Delacour’s Fireback”.’ What, then, is Lophura ignita macartneyi? Ironically the problem of macartneyi may be resolved in a more direct manner. Temminck’s (1813) original description was based Methods and results on more than 20 specimens (‘plus de vingt individus’), at least one NJC examined 12 specimens of male birds catalogued as L. i. of which apparently survives (specimen 1 in Table 1), but these macartneyi at Naturalis, Leiden, Netherlands (ten) and the Natural represented a variety of forms, crucially including Lophura ignita History Museum, Tring, UK (two). Clearly from the writings of Ghigi (1926) there are or were many more specimens in Italian museums, Table 1. Details of museum data associated with 12 specimens but the Leiden-cum-Tring material provides a slightly larger sample described in Table 2. than that used by Delacour (1949).
