??? what's a cockteil?
Living one day at a time;
Enjoying one moment at a time;
Accepting hardships as the pathway to peace;

What's special about their mating?

I think for most birds, reproduction occurs by the males fertilizing the egg externally after the female has laid it. correct me if I'm wrong.

I would say correct, that's why I'm asking what is special about them?

thats not true at all, birds fertilize eggs internally - sperm transfer through touching cloaca

As far as I know there is nothing unusual about a cockatial's mating process. They mate the same way as other birds. Also to my knowlege there are no fully terrestrial eggs fertilized externally. Perhaps some of the invertebates do?

u cannot externally fertilise an egg with a shell so it became necessary to evolve internal fertilisation which would allow the sperm to get into the egg before shell formation :roll:

Hi

Fertilization is definitely internal in birds via cloacal insemination and fertilization occurs even before the shell is processed around the egg...........thats what I studies way back about 5 yrs..........dont think things have changed much since then........

Fertilizing eggs

Post by mofmars3 » Sun Jul 30, 2006 1:07 am

Wow...I thought I was the only one who used to believe birds fertilized eggs externally...My cockteil keeps laying them and they sit and sit, diligently...No little birds, ever...He won't touch her...He does hump his perch though...I wish he would get smart but this is like the 5th batch that I know he won't figure it out now...Any advice? :D
