INTRODUCING
SPANGLES
by
John Scoble
Like
several other Budgerigar mutations, the Spangle first appeared in Australia, so who
better to reflect on the past and future of this beautiful variety than Australian expert
John Scoble, who wrote this in 1994.
In my
view, much misleading information has been published about the origins of the Spangle
Budgerigar - even to the extent of the parents being identified. I am certain we will
never know how and when the first Spangle was bred as, almost certainly, the person who
bred it did not realise it was a new mutation. According to the late Frank Gardner, a
Budgerigar breeder of high repute, Mr Jones of Victoria was the
first to recognise they were something new and managed to acquire a number of them.
After a period of
colony breeding they came to the notice of the Budgerigar Council of Australia. This was
in 1977. The first time Spangles were seen by the general public was when they were
exhibited in Melbourne. Although
Frank Gardner advised Mr Jones to hang on to them, he was presented with a pair of
Spangles. Thus, Frank Gardner became the first exhibition fancier to breed with Spangles.
Frank's
record-keeping was very precise, extending to such details as cheek patch colour and mask
spot configuration and so it may well be best not to pay too much attention to the
word-of-mouth histories of the Spangle and to concentrate on what Frank Gardner's records
have to tell us.
It is acknowledged by
customs officials that large numbers of eggs of many varieties of birds are smuggled into Australia, every
year. It is said that the first three Recessive Pieds entered Australia from
continental Europe in this
manner in the early 1970s - a couple of years before the first Spangle appeared.
The
link between radioactivity and mutations is well recorded and this prompted me to follow
up a particular line of investigation. Airline luggage passes through X-ray checks and, in
addition, there was a radiation scare over Victoria
around the same time. I checked with a poultry research centre and was told that the level
of radiation, in the circumstances described, could not be responsible for the mutation of
the Spangle.
It
was explained to me that - although mutations of plants are caused deliberately under
strictly controlled conditions - it would take a higher level of radiation occurring at a
specific moment in an embryo's development to have caused a Recessive Pied to mutate to a
Spangle. As far as I was concerned this put an
end to this line of thought. Even so, I consider it strange that the Spangle mutation did
not appear elsewhere in the world, as happened with other mutations.
Interbreeding
Dutch Pieds with Recessive Pieds has demonstrated that grizzle markings, so characteristic
of the Recessive Pied, can be transmitted to other Budgerigar varieties. Furthermore, A.
Brown, of Sydney,
bred the first Dark-eyed Clears in Australia from
a Recessive Pied. For me, this strengthens the theory that Spangles could have mutated
from Recessive Pieds, even if it was not as a result of the radiation sources previously
identified.
The
undersides of many Spangle feathers are grizzled, Spangles and Recessive Pieds both have
broken cheek patches and early Spangle hens had much darker wings than their male
counterparts - a feature shared only with the Recessive Pied. I possess Recessive Pied
wing feathers that look very much like those taken from Spangles and clear head spots are
common to both varieties.
Militating
against the relevance of the head spot is the fact that this has been appearing on
Budgerigars in Australia (New
South Wales and Victoria for
40 years. Such birds had been shown regularly in Victoria) and
birds marked like this often won Pied classes. Thirty years ago, I discussed the
appearance of head spots on otherwise Normal birds with the man I rate as the greatest
bird man I have ever known; Billy Hoare of Sydney. Mr Hoare maintained that they were a
recessive form of Pied.
The
Spangle mutation appears to be unique in that it has a factor which rearranges the
pigmentation within the structure of the feather and, in addition, possesses a recessive
modifier that acts as a diluting agent (to produce the Double-factor Spangle) when
inherited from both parents. This is a phenomenon that exists in no other mutation. The
first Double-factor Spangles bred by Frank Gardner had no ghost markings on their wings or
body colour suffusion when in nest feather.
The
whole question of coloration in Spangles is confusing because no two Spangles seem to be
the same. In my experience, the markings of most single-factor Spangles reduce in density
at every moult, while the opposite is true of double-factor Spangles, in which there can
be intensification of wing markings (including under the wings) and body colour at each
successive moult.
One
of the tasks that needs to be tackled is finding how to maintain colour intensity on
single-factor Spangles. It is frustrating when markings at the nest-feather stage
approximate to the ideal, only to fade with time. I feel that successive single-factor to
non-Spangle matings could be to blame for the loss of distinctive features such as the
target-shaped spots and split-coloured cheek patches. In a lecture I presented at the 1985
Budgerigar
Society
Convention, I recommended using more Double-factor Spangles in pairings and experience has
shown that this approach has produced better-marked Single-factor Spangles.
Photographs
of early Spangles in my possession show just what has been lost. They had brighter body
coloration and distinctly marbled markings. Flights and tails had a dark edge which
greatly improved the outline of the whole Budgerigar. This was demonstrated clearly in the
course of experimental work that I carried out with wild Budgerigars, in conjunction with
Neville Seage and Gary Heather of Sydney -
whose contributions I rate as absolutely invaluable.
When
a wild cock was paired with a Spangle hen the resultant Spangles displayed the beauty of
the originals. Their spangling was superb, even though there was coarser feather and more
down on the youngsters. Such results must encourage specialist breeders as they
demonstrate what can be done - in practice, not theory.
