I decided to take a video of my budgies bonding, preening and kissing.
I hope you guys enjoy.
I appologize for the poor quality, i couldn't get my HD camera inside the age so i had no choice but use my mobile phone.
Freki and Loki: Budgies bonding and kissing - YouTube
I am very much almost certain that Frost is a recessive pied, but I am not 100% sure because her wings and stripe color throw me off a bit.
Loki, I just downright have no clue. I've not seen a picture of any budgie that looks like him that states what kind of color mutation it is.
