The English ornithologist
John Gould described a specimen of the russet sparrow collected in the Himalayas at a meeting of the
Zoological Society of London in December 1835 under the
binomial name Pyrgita cinnamomea. His description was included in the volume of the society's proceedings for 1835 that was published on 8 April 1836. Its
specific name comes from the
Neo-Latin , "cinnamon-coloured". The russet sparrow was described as
Fringilla rutilans, by the Dutch zoologist
Coenraad Jacob Temminck, from a specimen collected in
Japan. Temminck's description is contained in his ''Nouveau recueil de planches coloriées d'oiseaux
which was issued in 102 livraisons
or parts between 1820 and 1839. It was at one time believed that the livraison'' containing the description of the russet sparrow was issued in 1835 but it has now been established that it appeared sometime in 1836 but as the precise date is not known under the rules of the
International Commission on Zoological Nomenclature it is deemed to have been published on 31 December 1836. Most taxonomists give priority to Gould's publication and use the binomial name
Passer cinnamomeus for the russet sparrow. The russet sparrow has usually been placed in the
genus Passer, and within this genus it is seen as a part of the "
Palearctic black-bibbed sparrow" group, which includes the tree sparrow as well as the house sparrow. It has generally been seen as a close relation of the house sparrow, and
Richard Meinertzhagen even considered it to be the same species as the
Somali sparrow, one of the house sparrow's closest relatives. However, studies of
mitochondrial DNA indicate that the russet sparrow is an early offshoot or
basal species among the Palearctic black-bibbed sparrows. While mitochrondrial DNA suggests
speciation in
Passer occurred during the
Miocene and
Pliocene, Thirteen
subspecies have been described, but only three are widely recognised, these differing largely in the colour of their underparts. The subspecies
Passer cinnamomeus rutilans breeds in Japan,
Korea,
Taiwan, and southeastern and central
China. The subspecies
intensior, described in 1922 by
Walter Rothschild from
Yunnan, breeds in southwest China and parts of
India,
Burma,
Laos, and
Vietnam. In a large part of
Sichuan intensior intergrades with
P. c. rutilans, and a number of subspecies names have been proposed for the intergrades. The
nominate subspecies cinnamomeus, described by Gould from the northwestern Himalayas, breeds from northern
Arunachal Pradesh to
Nuristan in
Afghanistan. == Description ==
