The use of anthracite coal was restricted due to the difficulties in transporting it efficiently, and the industry was still small and undeveloped (Latzko, 3).

During the war the British blockade of American ports severely limited the supply of British
Anthracite budgerigar mutation two factors will deepen the body colour even more. Anthracite budgerigar mutation The Anthracite budgerigar mutation is an extremely rare mutation that occurs in the budgerigar. The mutation, similar to the Violet budgerigar mutation, causes a difference in the coloring of budgerigars.

The mutation is believed to have started in Germany, and tends to be local to that area. Currently, most owners wishing to obtain an Anthracite need to import these budgerigars from Germany.
