I use photobucket with good success.

I prefer using the L-shaped nest boxes. The hens almost always lays their eggs in the part that isn't directly under the entrance hole, so I use that as motivation for myself that they prefer it to normal nest boxes. But, as long as it is dark, they'll be happy.

Johan S

Willy, in the words of one of my favourite authors, "So long, and thanks for all the fish!" It was interesting and a privilege to discuss turquoise, indigo, emerald and deep with you, esp. your knowledge on structural mutations that you have shared freely. It's a pity that you can't allow ...

Johan S

Ben, I'm fairly sure recessive genes can show themselves in combinations, like in your grey dom. pied / CT. Our mauve SL dom. edged / CHF cocks also have a different mandible colour. Madas, do you think the father cleartail dark turqblue is split for NSLino? Unless it is simply the moult, the bird h...

Johan S

John, it's a real pity you missed out on an opaline hen! I rate them in my top 3 mutations. Maybe you'll be surprised with one popping out next year. That'll be a nice surprise. Do you think something else is at play? I have no experience with dom. pieds, but we see A LOT of variation in our adm rec...

Johan S

How can you say that Ben when you haven't explored the alternate hypothesis that Opaline and Harlequin are just variants of the same mutation? Recio, Johan?? :wink: I forgot something Willy, I asked that exact same question! :wink: And it turns out my opalines breed with a sex-linked recessive inhe...

Johan S

Nice one Ben. What are we looking at? Dark, violet, deep?

For interest sake, could you photograph that one for me in full sunlight? Pretty please.

Johan S

About the possibility of the Blue-1 and the Blue-2 loci being in the same gene ... it is not possible due to the definition of a gene, just coding for a protein. But I agree with you that définitions do not stick to reality many times. Recio, are you saying that the approach of two different blue a...

Johan S

Prodigy, Jurgen has that bird labeled as a dominant pied in Facebook. And it looks like one too. Did he say it is something else?

Johan S

Willy, where does the underlined fit in? On the basis that all alleles of the same locus found in any parrot so far are always of the same inheritance mode Johan, Recio is saying Emerald is dominant but at the Blue locus also. There so far as I am aware only sex-linked and recessive allelic mutatio...

Johan S

Oh damn, I just posted on that again. Sorry Ben! :lol: It was a suggestion only. +1 to Johan good job on stating what is fact and what is assumed to be because of the facts ;) but also due to lack of known alternatives. clears up the fog Ben, I'd like to caution to the over emphasising what is comm...

Johan S

Johan & Recio Should open a new thread on Blue 1-2 locus possiblity. Oh damn, I just posted on that again. Sorry Ben! Let's get back to Aaron's pairing, and hopefully I will now show why it isn't case close. Mike heavily hinted on this already. In the scientific method, one always has two point...

Johan S

Does this make any sens? I think so. Several years ago we discussed in the Yahoo forum that a second blue locus probably would be located near the Blue-1 locus because probably it would have been produced by a duplication of the Blue-1 locus (tween genes), and later it would had evolved independent...

Willy, that's a fantastic pic, thanks!

Johan S

Willy the images are on their way. parents are emerald turq blue dom pied to cobalt violet blue. interestingly the pin feather lines on the rump to tail look violet. Lee, it will be interesting to see how this little one feathers out in the next few weeks. Do you have a cobalt emerald to compare wi...

Johan S

Recio, this bottlebrain doesn't allow for much creative thinking anymore. I leave that to my ancestors. I did ask them if they were considering that the mutation was exclusively from the north eastern flock, and could be expressed in the rare blue series more common in the east, or whether it could ...

Johan S

It is my view that it is possible, albeit highly unlikely, that a gene could appear at an as yet unidentified locus to create emerald yellow by either pigment or structural means. It is not unheard of for new mutations, that haven't been identified in other species, to show themselves in ringnecks....

Johan S

Ben, those pics are fantastic. They are zoomed in so much, you can almost see the psittacin granules already. :lol: Speaking of, I've heard from a friend that they get rather nice photos at a microscopic level with their camera phones (was an iPhone) and a lens from a lazer pointer. Apparently there...

The underwing patches seems much more evident than the "yellow socks" I always try and find in photos. Great catch, guys. Will be reading this post with great interest.

Recio, although I am little more than a brain in a jar attached to a robot body in 2213, I do still enjoy puzzles and aviculture. Although it feels like I should have the answers to your puzzle, I'm afraid the brain transplant has left many gaps in my memory. My descendent, Joaquin (named after a gr...

Johan S

why in heaven would you want to feed a parent reared 6 week old bird? 1) Because the parents died from a bacterial infection in the crop (heaven knows how the chick survived). 2) Because there is an extremely dominant sibling starting to kill and/or starve the other chicks just prior to fledging. 3...

Johan S

In your version, shouldn't there be two enzymes? One from b1_a, B_b, the other from B_a, b2? :?: I think what you are meaning is that your single enzyme consists of a single protein. In my meaning, an enzyme consists of two of the same proteins chained together. You have a binary system with resolut...

Johan S

I have many other interests in my life than to read all about all the possible science which affects other creatures. This is an IRN forum and this thread is being used to discuss a second Blue alllele in budgerigars. Not interested. No man, Willy. 80% of my post covers parblues for IRN. You only n...

Johan S

Madas, you are correct only under the assumption that an enzyme is made of only a single protein in the chain. But that doesn't explain the budgerigar results. "If the enzymes produced by this series of alleles consisted of only a single protein chain then there would be no ‘Mutant 1’ Yellowfa...

Johan S

Madas, I believe the section "Protein structure" in the original article attempts to cover your query. Keep in mind, I'm not a geneticist, so I could very easily incorrectly use the terms. Further to this, I don't dare pretend to understand how the chain - DNA - protein - enzyme - psittaci...

Johan S

Willy, because at the heart of the matter, no matter the species, we are all a result of some very similar biological process. Today, however, I would like to state for the record that there is a grey area caused by our basic definitions in simple genetic models. When we define a blue mutation, we a...

Johan S

Bravo Johan. Apology accepted. There is no place for sarcasm on this forum and I am allergic to it. Ask Recio. I was guilty of it sometimes on Terry's forum but I was truly exasperated at the posts by the Mad Cow and the Caveman and yet silence from Terry who could have stifled it, not with reprima...

Johan S

Hi Ben, for me there are two. :D #1 Love green, green is your friend The very first thing to realise is that disregarding the green series is a mistake (I mentioned "mistakes of the past", I will elaborate shortly). I fully agree it sounds completely counter intuitive to breed parblues in ...

Johan S

Mike, the following might be of interest to you. If Emerald was structural logically Grey would destroy that structure also. Wrong. Willy has generalised too much. The barbules consist of at least three regions of structure. The center where melanin is deposited, the spongy zone and the cortex (oute...

Johan S

I have not seen a mature DF indigo cock. Does the same phenotypic difference still hold, i.e. no psittacin in the neck ring (i.e. only black and white)? My mature df Indigo cock was killed by a hawk, major set back. It had a small amount of colour in the neck ring. Why should it not? The hen is all...

Johan S

Willy, I'll try not to go off the beaten path in this thread. I agree with the first statement. Then: The hetero. Emerald IRN has psitticin so it cannot have 2 Blue genes. If we look at this statement, this is where the difference of opinion lies. I will stick to the facts, but please correct me if ...

Johan S

Me too and i am not convinced it is a deep. I am sick of this doubting. Read my lips, the bird was bred from a Deep. Ron is not a stunned mullet. I will tell him that he will not be believed until he puts it with a Dark Green also, he will probably say "tell them get mated". You wonder wh...

Johan S

What's stuck up your cloaca today Johan? Johan you know where to stick those Deep feathers I sent you. Dear Willy, I sincerely hope that you feel better after that little outburst. Perhaps now you can show us a picture of a proven green / emerald to convince the open minded that it is indeed recess...

Johan S

In saying this, I am also mindful of the statement on this thread that an Emerald Green Alex exists that was difficult to identify as such. But then it still could be a rec. mutation of the blue locus. Some ADM rec. pied splits show yellow feathers in the flights. But this mutation is commonly acce...

Johan S

In fact as I am convinced that Cobalt is a dead end I am going to get rid of most of them. Cobalt starts destroying the structure as does a Mauve when more than 2 structural mutations are present (not counting Blue). Johan has DF Violet Cobalts and can confirm this. They do tend towards mauve, yes,...

Johan S

Hi Willy,

I have not seen a mature DF indigo cock. Does the same phenotypic difference still hold, i.e. no psittacin in the neck ring (i.e. only black and white)?

PS: We can bash one another in the other topic, this is a friendly question simply to learn, no harm meant.

Johan S

Recio, if this effect is due to structure, it must be because of violet. We have a cobalt NSLino and no matter how closely I've looked, I've not seen this effect. However, a friend of mine have bred two ino birds from a violet cleartail line. If one is a cock, we can assume NSL ino, and hopefully vi...

Please have a look at this article on structural colour in birds. This quote is the clincher: These fundamental modifications cause violet and blue light to be selectively reflected from the feather surface in the case of violet/blue feathers, while white feathers reflect all visible light. In shor...

Johan S

Does the concept of emerald possibly being a structural gene necessarily mean it will be co-dominant and should we therefore be able to see some evidence of it in the green series? Would it also mean that a different yellow hue or tone might be produced by it compared to that seen with turquoise? M...

It reminds me something :wink: Perhaps you'd like to elaborate. :idea: And Ben... Not far enough out on the left wing yet. There is some more room to explore! :lol: I haven't seen the response I have been looking for. Winning bid still out. But Ben is closer than Recio, I think. My intention never ...

Johan S

Ben, you got the obvious part, but not the "hidden gem". Not yet, but I have full confidence you'll get it with just a tiny bit more encouragement.

Johan S

Ben, you are cheating to save time! :lol: But, there is an important point hidden in this little exercise. Who is going to guess it right first... :?: Willy, when reading the original post again, you'll see that the intention is to guarantee it. The puzzle is that homozygous parblues should be ident...

Johan S

Hi everyone, here is a puzzle with a couple of different approaches to solve. However, I'd like to know what you think the best approach is. The goal, we want to breed a homozygous turquoise from a collection of birds with parblues available. However, we have no guarantees to which birds are heteroz...

To me the pic of the emerald cock IRN posted by you earlier is a Blue Emerald Molussus, the image I have posted of an EmeraldBlue has obvious psitticin in its feathers. Yes or no? If yes it cannot be an Emerald Blue as Blue by definition removes all psitticins. If there is a Green Emerald in Alex t...
