January 19, 200916 yr Can anyone post pictures of yf1, yf2, gf, and double and single factor of those, because that would really help..
January 19, 200916 yr well im not as confused as i was , but that doesnt mean im sure im right either . here are a couple of my yf/gf birds anyway Gf cobolt cock yf2 cinnamon cobolt hen yf2 dom pied skyblue yf1 violet and yf1 sky violet spangle hen there are many different opinions ofcourse depending where you learnt your terminology
January 19, 200916 yr I wonder if New Zealand has all three varieties I have seen goldenfaces where the colour is in the face (BgB2) and goldenfaces where the colour runs into the body (BgB1) at the pet store and at show breeders aviaries. These are VERY apparent when paired next to normal yellowfaces, huge colour difference in the yellow production. We also have YF1 (i even have 2 YF1 birds or B1B2 alleles). I have a YF2 cock (seafoam green, ie ByfB1 as pete burgman would say) who produced three YF2 chicks, and i have a YF2 dom pied grey hen that is hopefully about to lay. Curiously, she is paired to the YF1, so i will be closely observing the chicks YF inheritance (fingers crossed they lay that is).
January 19, 200916 yr So Dean_NZ, would you say the three birds I posted above are all Goldenfaces? Is the top one a yf2?
January 19, 200916 yr Hi Jen144. It's really hard to judge on some photos, as i well know how flash, no flash, and ambient lighting all affect the appearance of colour on a bird. Zoom, resolution and stability also make it difficult. However, going from what i can see i would say... This bird below is a YF2 (By2B1) sky blue male This photo is difficult to judge, as my first impression of this budgie would be that it is a green series recessive pied. Failing that, it could possibly be a YF2 (By2B1) recessive pied blue. Again with this bird below, the clarity and lighting of the picture makes it difficult, but i would have to say this is some sort of goldenface composite. Given that you can have double factor golden face with the yellow presenting in the mask and spreading (mainly) to the chest, you could expect some spillage beyond that in some birds. So this 'could' be a double factor golden face. It could also be a composite form of golden face crossed with yf2, which is better explained by pete burgman as thus: The Mutant 2 Yellowface represents another allele in the series which like the Goldenface produces its own unique version of yellow-producing enzyme. Its the same breeding pattern as the Goldenface and the same foibles including spillage of yellow into the body colour due to the overactive enzyme (by2/b1). The only real difference between the Mutant 2 and the Goldenface is that the Mutant 2 enzyme is less efficient at producing yellow pigment than the Goldenface enzyme. Composites between Mutant 2 Yellowface and Goldenface do exist and likewise produce three versions of the enzyme namely (bg/bg) enzyme, (by2/by2) enzyme, and (bg/by2) hybrid enzyme. All three versions of the enzyme are active but the hybrid enzyme is not overactive. These birds closely resemble the double factor Goldenface. The Mutant 2 Yellowface allele can therefore be regarded as another homoallele of bg and b2. Edited January 19, 200916 yr by Dean_NZ
January 19, 200916 yr I seem to have all goldenfaces, possibly yellow faces. What do you think of these ones Dean? (Apologies to people who have seen these pictures about a million times before) I will leave out the goldenface and yellowface descriptions in their description, because I'm not really sure. This one is mother (with a normal blue cock) to the following (there was also a cobalt whitefaced clearwing/fullbody colour greywing spangle in the clutch too (I can't tell if they are clearwings or fullbody colour greywings)) DF spangle, clearwing/greywing fullbody colour, possibly mauve. (known from breeding) Cobalt spangle Cinnamon cobalt spangle Cobalt opaline spangle Violet opaline cinnamon spangle The following are mum and dad of the following Mauve clearwing/grey wing fullbody colour spangle Mum Skyblue normal Dad Clearwing/fullbody colour greywing cobalt spangle Their offspring This pair also had a whiteface violet opaline. They've all had flash used on them, as they appear much more vibrant in real life. Edited January 19, 200916 yr by Sailorwolf
January 19, 200916 yr okay, so YF1 is when the bird has a light yellow/cream coloured face. But how do I tell the difference between a yf2 and gf? A yf1 when it is df will go white, correct? But a df yf2 and a df gf won't? is there such a thing as gf 2? In australia you only need to worry about YF M1 i.e. Creamface and GF i.e. Goldenface The only reason Australia does not have the YF M2 is beacuse the government would not allow imports into Oz. Sure birds were smuggled both ways or from Oz to Europe and then to the UK. Not too many birds came from the UK into Oz. Yes JB a df YF M1 is a white face bird. Ken Grey's book Rainbow Budgerigars and constituent varieties clearly states the differences between the yellowface mutations. If you can get a copy of this book you'll will find it a worth while investment. Both YF M2 and GF can be found in the double factored form. Below is a picture of one of my DF Goldenfaces I bred. Although it is hard to see as the quality of the picture is not the best, this bird does show some yellow on the back of the neck and there was some still in the wings and tail feathers and very slightly in the body. This is normal and will vary depending on the depth of the Sky, Cobalt, Violet or Mauve colouring as these themselves vary from bird to bird. Its called variation. All species must have variation in order to survive. If Australia has no yf2..then a bright yellow faced bird with yellow all through the wings markings, head, and body (making it a sea green colour) is what exactly? A single factor gf? So, let me see if I got this right. We (australia) have no yf2. So we only have yf1 (double factor, causing a white face bird, and single factor, which is a cream faced bird with little to no yellow in the body) and gf (double factor, which is as the picture above, and single factor, which is like a yf2, a sea green coloured bird as all the yellow goes throughout the entire body)?? Correct And the bird I had asked about originally which caused this thread to be started..http://forums.budgiebreeders.asn.au/index.php?showtopic=24267&st=10&gopid=288649&looks exactly like that picture above. What is she, a double factor gf, as her face is not cream coloured but a bright yellow? As I already said in my post in reply to your thread she is a double factored Goldenface. The definations of which yellowface is which is not decided by the confines of the yellow. Here is another photo to ponder over. This cock is a single factor Goldenface Cobalt Grey(sf). He shows a slightly paler yellow face because of the family line he belonged and the fact he was a Cobalt Grey he shows only a small amount of yellow suffusion As I keep mentioning variation. I had a particular family of Goldenfaces that excelled bright yellow faces. They could be the brighter yellow spoke of by Ken Gray. I had another line which I would say could well be like the YF M2 of the UK. All my GF did have one thing in common though I had managed to breed and beautifully natured line of birds many of which went on to produce the best pets some of which even went on to be good talkers. It's all in the genes. Many of the breeders I associate with refer to the English imported yellowface as creamface or just yellowface and the Aussi bright yellow-faced bird are referred to as Australian Yellowface or goldenface. Most bird you would find benched at shows in the yellowface variety will be creamface as Australian yellowface aren't usually competitive. I really like the Australian Yellowface variety and keep a very small number of them. Complications can arise when creamface and Aust yellowface are bred together and/or when other varieties and modifiers such as dilute are part of the mix - the birds can be quite difficult to identify if you do not know the breeding history. I skimmed quickly through all of the posts in this thread so may have missed some info.
January 19, 200916 yr Author http://forums.budgiebreeders.asn.au/index.php?showtopic=9447 Here is an article from Jim Sutton there is a bit in there about YF also members have added some photo's of there "type 1 & 2 & GF" this includes Daz & Kaz so saying that there is no such thing as a YF 2 seems strange whether we are in Aust or Africa it is something that we here have all "termed" and can identify with so now to call it something " correct" seems strange in more ways then one HERE IS THE ARTICLE that i think RIP is referring to Neat I got this from the thread that you posted... Yellow-facesYellow-faces are another Dominant variety. Obviously, they only appear in the Blue series. They can be also in the Green series but it is extremely difficult to identify them. In the Blue series they should have a yellow face in lieu of the white, the yellow should go over the head to the back of the neck, it is a major fault for the yellow to extend into the body shade. I don't know how many times I have read on here that if it goes through to the body that means it is YF2... that quote implies that any YF mutation can extend into the body shade... and says that it is a major fault... this quote would align itself more closely with RIP's view than others... (so far KAZ and DAZ haven't replied to this thread so I am not sure what their opinion is... ) Yellowface budgerigars have probably had more written about them than any other variety. Opinions differ about what Yellowfaces really are and debates about Yellowface genetics have at times become quite heated. Gotta love that as an opening paragraph...

There has been a proposition, which I tend to agree with, that in show schedules yellowface should be between green and blue series normals as yellow face subtracts the yellow from the body colour of greens. If you subtract the yellow from mask AND from body you get a blue bird.
January 20, 200916 yr okay firstly i owe rip an apolige i got it backwards the golden face 1 the single factor form creates an even deep sea green colour (in colbolt) lime green ,mint in sky birds In double factor form the head is golden and the yellow bleeds into the upper portion of the body colour creating a dark blue green while the lower portion retains the blue colouring . the spread of yellow into the body becomes more progresive with each molt i find after the third molt you can be sure which typeing you have for defenent here are some my yellow face birds remembering i am not as knolagable with my knolage so only going by what books say and from test breeding knolage okay first my gf2 colbolt . his fater is a gf2 sky rececive pie /opaline mother a opaline sky 1f violet spangle ,cinnimon wings next his father now his daughters to a gf2 sky dompie i found he is /opaline and cin the picture bellow both same clutch bird from above and sister colbolt gf2 dompie this above bird sister from second clutch and the bird bellow my df dom sky yf2 not golden face yellow face two the mother of these three i will post some pics of my cinnimon yellow face chicks from the same birds they are type 2 like mum not golden face have to up load to photo bucket so dont hold your breath i will post my type one yellow face and my type two yellow faces then also this next one gf2 rececive pie i dont kinow what mutation only that she is opaline and i think grey green this next bird is the gf2 sky rec pies chick from another hen its also gf2 sky
January 20, 200916 yr Author when you say gf2 GB are you sayind double factor GF or are there 2 types of GF as well?
January 20, 200916 yr when you say gf2 GB are you sayind double factor GF or are there 2 types of GF as well? You beat me to the question jimmy Im afraid after reading pete's article so many times in order to write these posts that now i can only think along the lines of his writing haha. In saying that, i would probably label generic blues birds differently than he has. As always, its difficult with some photos to judge the vibrancy and/or spillage of the yellow.

In saying that, i would probably label generic blues birds differently than he has. As always, its difficult with some photos to judge the vibrancy and/or spillage of the yellow. well i was taught two diffrent things their is golden face type 1 and goldenface type 2 basiclly that is gf single factor gf double factor k, single factor golden face works like the yellow face type 2 mutant exept they are seperate geneticlly the diffrence is in the colour of the yellow a golden face is a deep butter cup yellow and the yellow face type 2 is dark yellow but still not golden hence the name in a single factor the it (the yellow) blends down and into the body colour making the blue turn either a deep emarald green or mint lime green depending on weather the bird is sky blue or colbolt in a grey bird the type 2 yellow turns the grey deep olive green mauve is somewhat the same only not as olive more moss green the bird will be totally green after all molts eg this bird is a sky gf single factor she is fully green no hint of blue bar mabe near cheeks her brother is gf2 double factor he his only part green hence the name par blue. so goldn face the coloure goes into the wings and the lower body stays blue this is double factor single factor the bird turns green of verious shades depending on colour single factor yellow face the birds colour does not change and only the face is yellow type 2 the birds face is yellow not buttercup just deep yellow its body like a double factor golden face gets a slight bleed but lower stays its original colour i have to go but i hope that helps i will take all updated picture and if i must i will do a photo of young bird then mature bird
January 20, 200916 yr Look at my signature.The "green" bird with Arkady under his picture is a Goldenface. He looked almost exactly like a bright green bird. I know he is a goldenface as he was blue when I first bought him. This is Arkady; a goldenface: now thats what im talking about sailor a single factor golden face and explained so simplisticly Edited January 21, 200916 yr by maesie
