Jankowski's Bunting (Emberiza jankowskii) is a small bird with narrow distribution ranges. It has experienced a drastic population decline during recent years and vanished from most of its historic breeding sites. It has been recently up-graded as Endangered in the IUCN Red List of globally threatened species. By integrating unpublished data of field surveys conducted by us and published information on the species, we provide information on the status of distribution, breeding biology of the remaining population at the Dagang Forest Farm, population trends at currently known breeding sites, selection of breeding habitats and threats faced by the Jankowski's Bunting. In light of its current status we also suggest ways and future research work related to protecting this bird species.
The Russet Sparrow is a rather common and widespread species of the Oriental Region. Three subspecies are generally recognized, including Passer rutilans rutilans (Temminck and Laugier de Chartrouse, 1836), which breeds in China east of Tibet, Japan and adjacent parts of East Asia, Passer rutilans cinnamomeus (Gould, 1836), which inhabits the Himalayas and adjacent mountain ranges, and Passer rutilans intensior Rothschild, 1922, which lives in Southeast Asia (Moreau and Greenway, 1962; Clement et al., 1993; Dickinson, 2003; Summers-Smith, 2009).
Temminck's rutilans and Gould's cinnamomeus were long considered similar, but separate species until Hartert (1904:161–162) lumped them into a single species. Hartert (1904) incorrectly dated Temminck's and Gould's papers to 1829 and 1835, respectively, and accordingly called the species rutilans, which name he believed to have six years precedence over cinnamomeus. Recent advances in bibliographic research indicate that cinnamomeus has precedence.
Temminck published the name rutilans in the binomen Fringilla rutilans in the text accompanying plate 588 of his and Laugier's Planches coloriées. This plate appeared in the 99th livraison. Hartert (1904:161) said that the plate appeared in 1829 without explanation. Crotch (1869:500), Sherborn (1898:488), Stresemann (1922:54–55) and Zimmer (1926:627) believed that livraison 99 appeared in 1835 (closer date unknown), but Dickinson (2001) documented that this livraison was published only in 1836. A closer date being unknown, the work is deemed as having been published on 31 December 1836 (Dickinson, 2001: 47; ICZN 1999, Art. 21.3).
Gould published the name cinnamomeus in the binomen Pyrgita cinnamomea in a report on the meeting of the Zoological Society of London held on 8 December 1835. This report appeared in the 36th issue of the Society's Proceedings and was included in the volume for 1835. It has long been established that this issue appeared on 8 April 1836 (Sclater, 1893; Duncan, 1937; Dickinson, 2005; Peterson, 2011).
All other synonyms were published much later and do not compete with Temminck's rutilans and Gould's cinnamomeus for priority (Hartert, 1904: 161–162; Moreau and Greenway, 1962: 13–14). The earliest name for the Southeast Asian subspecies is Passer rutilans intensior Rothschild (1922:11).
These data allow to conclude that Gould's cinnamomeus was published on 8 April 1836, while Temminck's rutilans appeared on an unknown date within 1836, i.e., unless shown otherwise, on 31 December 1836 in the sense of the International Code of Zoological Nomenclature (ICZN, 1999, Art. 21.3 and 21.7). Hence, cinnamomeus has priority over rutilans.
The Russet Sparrow thus should bear the name Passer cinnamomeus (Gould, 1836). Its three generally recognized subspecies should be called Passer cinnamomeus rutilans (Temminck, 1836), P. cinnamomeus intensior Rothschild, 1922, and P. cinnamomeus cinnamomeus (Gould, 1836).
