From the Reise der österreichischen Fregatte Novara [...] Zoologischer Theil, A. Pelzeln, "Vögel":

"Males and females shot on the moor near Constatin. Not uncommon in foliage, especially on Ericaceae, in which it also mostly builds its nest. Because of its excellent colouring, this bird can be seen from a considerable distance and is therefore easy to kill. Zelebor" (p.90)
