blue head gouldian???

[bernd76287]

Interesting about the blue eyes You know the sky isn't really blue...it just looks blue due to the light reflecting and how we perceive it
Same with bodies of waters, ice glaciers, fog... all depends on the lighting...
Seems in all of nature blue is only possible with light

... and if we consider, that every creature has his own active zone of seeing (I mean the "light spectrum" we can only wondering.

I don't know how they know this, but they say (in the same books mentioned earlier) that Gouldians can see ultra violet colors, so they see each other different than we see them
I think the fusion bar really plays into this because every hen that gets a glimpse of my fusion bar goulds they get smitten with him immediately
I also think this has a lot to do with the hen picking their mates.
Even if we think the colors we put together look awesome... they can see things that we simply can't.

They know because of the types of cells in the retinas

Humans have three types of color receptor cells (cone cells) which is why what we have is called "trichromatic color vision."

Some birds have up to four cone cell types, and pigeons are thought to have five.

What we see versus what other animals see is determined by the wavelengths that the cone cells in our eyes can process, which for humans is wavelengths between 380 to 740 nm "the colors of the rainbow" basically.

Bees can't see into the red spectrum but they can see ultraviolet, because their cone cells register a different band of wavelengths than ours. So basically their wavelength reception is shifted back in the spectrum, but they are also trichromatic.

Just got interested whether the feathers of RHs are different!

1: RH DF Yellowback
2. RH normal
3. Tanagerine

I see differences in the melanines, deepness of red and the length of the feathers.
What do you think?

Now I took some feathers from a RH or YH silver =4
As you can see the color is not at the end of the feathers!!!

The picture of the 2 RHs shows father and son.
The mother was a RH blue.
The father a RH split blue, split cinnamon.

I got an USB-Mikroscope!
Very interesting what you can see!?

[CandoAviary]

Awesome Photos I haven't been able to get the pics from my microscope to come out without being blurry... I'll practice when I have some free time...if ever
It is amazing the diffence in the length of the black head feather. The tangerine is almost modified like the mosaics in canaries... both in width and color saturations. Interesting

[lovemyfinch]

Amazing
Is it just me, or would this mean that the tangerine is probably a YH with the modification of the colouring as the edges closest to the shaft is yellow?

[bernd76287]

I will take more pics in order to understand better the color of the gouldians.

Looks perhaps like in the "tangerine" there is some amount of melanin reduction in the feathers?? It seems like that might account for the difference in color?

I couldn't see this! But I am no expert only curious. I presume that the difference in color comes from the inhibition of processing yellow lutein in red xantanxanthin!??
YH Gouldians are orangehead because there are brown phaeomalins in the headfeathers too or ... ???; therefore RH silvers have this salmon called headcolor????
But please tell me if I am wrong. I add an picture of a RH.

Bernd, I seem to get a lot of odd balls in my bunch but the three that are pictured above were swapped at a bird fair... I found them different and unusual but the broker couldn't tell me much , actually nothing on the background genetics... thought I would figure it out... but haven't....
I just really am intrigued by the slight differences in these mutations, but am just a new student in genetics... that's wht I am always asking Tiffany... she has much knowledge in genetics

Perhaps Tiffany knows anything!??
Here a picture of the brothers. The belly has a normal dark yellow color.
If this variation is inheritable you could get OH with light orange color?????
Would be interesting!

I Bernd!
Amazing birds! "Superbes"!!!
Question: For you, are they Seagreen or not? And if not, how can we call them? Because they seem to have caracteristics of "Seagreen" (nice intense seagreen back...) And in many pictures of seagreen, the red head seem to be "Tangerine"...like if the color is "washed" by blue genes...
The question probably is: what is really a Seagreen... Weak green back split blue? Green back with strong blue split? Dark factor inhancing blue split? For you, are they automatically split to blue or it is some other distinct genes (nor green or blue but "seagreen"...)?
