Speckled Bustard
  Florican Bustard

This is the common English name for many genera and species of African, European, and Asiatic birds related to cranes and rails whose barred or "speckled" feathers range from tan or cinnamon to dark-brown or black. The largest of the group, the great bustard, weighed as much as thirty-two pounds and had an eight - foot wingspread. Almost all of them are useable in flydressing. However, they are also protected and on the CITES list of Endangered Species.
Speckeld Bustard is called for in lots of patterns; the most common being however, the African Kori Bustard. Substitutions can be found in turkey tail feathers, peahen saddle feathers.
A variety in some tying mail-order catalogues is often listed as Speckled Turkey. The Florican Bustard substitute is silver pheasant tail dyed tan. When you pick out a few fibres for use in winging, there is no big different between Turkey and Bustard.
