(Thraupidae; Ϯ Short-tailed Finch I. brachyurus) Gr. ιδιος idios peculiar, distinct; ψαρ psar, ψαρος psaros starling; "III. Genus IDIOPSAR, nobis. In the collection of the Smithsonian Institution I find a specimen of a very interesting and singular bird, evidently Icterine, and allied to Quiscalus and Scolecophagus, but not to be referred with any considerable degree of propriety to either of those or to any other genus of this group. The tail is short, nearly even at the end, and emarginate, and the wings long. General form short and compact, bill about the length of the head, strong, slightly curved, with the commissure much inflexed in both mandibles, culmen distinct. Legs and feet moderate. 1. IDIOPSAR BRACHYURUS, nobis. Entire plumage of the head and body bluish cinereous or plumbeous, darker on the upper parts and lighter on the under parts" (Cassin 1866). In ornithology psar also signifies members of the American Icteridae, formerly united with the starlings Sturnidae. Schwenckfeld 1603, used psar as an alternative name for strouthos, the House Sparrow. This bird is also known as Andean Boulder-finch.
