Good to be on-line again....
Was wondering if the experts can tell me if this is a typical new mutation?
Has anyone seen "Spangle-type markings" like these extend into the tail feathers before?
Some other questions I had on the subject are:
1) What type of feather-pattern / colour change(s) would indicate the start (re-birth, for others that have disappered) of any new mutation?...and how would a breeder know if it's new, except by comparison with existing mutations maybe?
2) Knowing that the majority of the current mutations (i.e. deviations from the "normal" Green...with exceptions being the recent Anthracite occurence in mid-1990's, maybe the more recent Dusk, Brown-wing among others & the very old variations, e.g. Buttercup, Lemon & Yellow between 1870 and 1910)... most occurred during the early 20th century (between 1910 and 1948,when the Lacewing arose)....why then has such "natural mutating" ceased?
..the question is...If these mutations arose back then (& given the "general rule" that mutations cannot be bred on purpose)...why cannot it occur today still?
Maybe the "Lacewing" producing occurences (so-called "cross-over") are examples of "ongoing mutatations" that do occur...but aren't we all "missing some"..when it actually happens; by failure to recoqnise?
Why wouldn't new mutations appear at least once in a decade?...has the genetic pool been depleted / have it become "saturated" (given the possible variations)...dare I ask, is it a result of current breeding practise / lack of recognition by the WBO and other organisations?
It would be good to hear what the experts breeders have to say on this...
3) Am I lucky with the above example...or is it just a "good example of a 'YF TII Cobalt Spangle' bird preening itself from it's uropygial (preen) gland...?!"
EITHER-WAY...I HOPE YOU ENJOYED SHARING IN THIS COLOURFUL DISPLAY...
..IT SURE MADE MY DAY LAST SUNDAY.....I was fortunate to have camera ready, when "Black-Cap" came across to "show-off" a bit!!..
Awaiting Ur comments?
C U later,
