Prunella montanella -- Siberian Accentor. Alternate name on piece: Accentor montanellus [Mountain accentor] Drawing on tissue. The flowering branch on which the birds are perched has been drawn around them, with no view of their feet, and with what appear to be rather inadequate twiglets as perches. In the published plate the birds and their poses are retained except for changes to the tails; the branch has been redrawn and heavier perches chosen. Artist's name(s): Gould, John; Richter, Henry Constantine.
