Albino Cockatiel


So I think we're going to try and breed an Albino next year. It's a bit complicated because there is no single Albino gene in cockatiels. The bird equivalent to the animal Albino, is the Lutino cockatiel shown to the left. Lutino have a sex-linked gene that prohibits the creation of melanin in feathers. Thus creating a bird that lacks all black or grey coloring.

Unfortunatly, cockatiels have to types of coloring: melanin and lipochromes (which produce the yellow and orange coloring). So, in order to produce an Albino you must combine the two genes. This is where it gets a little interesting genetics wise because while Whitefaced cockatiels ( cockatiels that lack lipochromes or yellow coloring) are recessive, Lutino's are sex-linked.

Then there's another curve ball when trying to figure it all out. Where as in high school biology we were taught that XX was the female and XY was the male, it actually is opposite in birds and its the female who is XY and thus chooses the gender of the offspring.

So the goal is to get a cockatiel with both White face and Lutino genes.

Baby Update


All five babies are growing quite fast and looks like all of them are pearled. This photos is a bit old so right about now they're just about ready to hop out of the nest and flex those wings in our big aviary. Can't wait!

Heads Up


Decided to take those eggs out today. Just as I had guessed, the parents had not been sitting on them. The new hatchlings look to be doing good and are just starting to put out pin feathers.

Caught this picture of Cinnamon the other day, a beautiful pearled cockatiel that I hand fed a few years ago. I think I may have surprised him a bit :D

Surprise!



Just finally got baby Elvis to start eating seed, and what do you know, I look in the nest of one of our whiteface and pied/pearled pair and there's not one, not two, not even three but five little hatchlings! ARGGG! Luckily, these two are our best pair parent wise so I'm thinking I'm going to keep them in there. They look to be about 10 days old, well-fed, and 2 of them are whitefaced.

I decided to put some eggs from another nest. The parents rarely sit on them and although I held a light to them and they look to be fertile, I think I waited a little too long :{ I'll give it a few more days and see what happens as I watch the new arrivals.
