The Melanistic Spangle
by Jeff Attwood
On my last
visit to Australia during May 1991 I heard of a new form of the Spangle which
had been produced in Brisbane, and decided to travel there and see it for myself.
These birds in
question had been produced by Garry Heuval who I had met on a number of occasions at the
Australian Nationals.
The birds showing
the melanistic markings had been originally produced from conventional Spangle stock but
the youngsters in question had appeared as normals in every respect except for the tail
which was clearly Spangle type.
They appeared in
both cocks and hens, and on reaching the second moult, the appearance of the birds changed
dramatically to that of what I have since named the Melanistic Spangle. Similar to the standard spangle form but clearly
quite different. Spots were very prominent
and solid in appearance, not bulls eyes as in the accepted Spangle form, and cheek patches
were clearly defined, not white flecked as is so often with Spangles.
The tail remained
original in the Spangle form, but the most eye catching change was in the wings and
flights, which took on a very clearly defined contrast, which I have heard commented upon
as almost a Spangle in reverse.
I took several
photographs and returned to England. I heard
nothing further of this new Spangle form.
During the 1998
breeding season, I produced from a Spangle Cinnamon Grey Green cock x Dark Green hen,
fifteen youngsters over three rounds. In the
final round one young cock appeared which in all respect was a normal Grey Green, but with
a clearly defined Spangle tail. The bird
eventually reached adult plumage and remained unchanged and my interest waned. Six months passed and once again the bird moulted
and with the passing of six weeks the appearance of the bird changed completely. It now took on the feather form of the birds I had
seen at Garry Heuvals birdroom in Brisbane.

In due course
these three youngsters developed in the melanistic form and were paired in the
breeding cage for the 2001 season.
Up to now only
one pair have produced, a Grey Green cock x Melanistic Spangle Grey hen. Three youngsters, one conventional normal Grey
(black tail), one normal Grey Green (Spangle tail) and one strange youngster which appears
to be a recognisable melanistic Spangle.

I have since
produced more of these youngsters, which in every case are always well marked conventional
Spangles, which do not change their appearance in any way when reaching the adult stage.
A number of
similar birds of this melanistic form have now appeared in different UK aviaries, and also
in Europe indicating that the mutation is here to stay.
The Budgerigar Society Colour Standards
Committee have decided that this
type of bird should be exhibited in the Spangle classes and penalised accordingly.
