I have a female and male pair of budgies. Smirky, the female one, seemed to get along with Moon, the little male, for the first 3 days i've had them. They preened and regurgitated in each other's mouths and stuff like that. They seem to have a love/hate relationship going on, Moon is very Beta and Smirky is very alpha. I've been told that Smirky is a "Dominant Yellow face", so that must be it. But Smirky enjoys being regurgitated into by Moon a lot and Moon enjoys getting preened by her. Every now and then for the first three days they made this little noise when they fought occasionally for more space and turns to eat but they always worked it out in the end. In another thread, I was asking about Smirky being positioned somewhere on the cage because Moon already was on a swing and Smirky really wanted to get on it with him but couldn't. The last three days she's been sleeping on the high wood perch and Moon has slept on the swing next to it. Today was strange, Smirky keeps making these "ACK ACK ACK ACK" noises. There seems to be no fighting going on, she makes them for no reason, whenever they do fight they make a different noise like a little squeak. I've read that the "Ack" noises means she's angry, but I can't seem to figure out what shes angry about. She seems to be picking on Moon alot more for some reason but then suddenly cuddling with him and wanting to be close with him. She is always picking at Moon's tail for some reason, like playing with it but it might not be playing. I have two food bowls and two water bottles in there. I feel like they are still fighting over the swing, but I really have no idea, so I might remove it and buy a bigger one for them. Moon is very quiet and occasionally chirps a tiny bit whenever Smirky does the "call" chirp. Oh yeah, Smirky flaps her wings vigorously sometimes whenever she does the ack ack noise, and Moon does this as well, except without doing the noise and less times than she does. I am worried their relationship is harmful or something. In the past hour it's been calm, they are both resting on the highest perch preening, not much has happened. Any tips?
I simply think that both are just settling into their new surroundings, and budgies are all individuals often with very different temperaments. As they are a mixed sex pair, you need to read the "stickies" from this site on preventing breeding, particularly regarding not placing any items in the cage that could stimulate nesting behavior. They're both beautiful young birds.
It takes budgies time to settle into their new environment and determine the "pecking order" so to speak. It isn't unusual for one budgie to be more dominant than the other.
All the behaviors you've described sound perfectly normal. Be sure you take the time to read all of the Budgie Articles and Stickies at the top of each forum section.
Doing so will ensure you learn a great deal about your birds, their behavior and how to give them the best possible care for their health and well-being.
Sounds like your birds are just settling in and sorting out their pecking order as was mentioned above. If it was real fighting, that would be a different story. What you are describing is normal.
When someone told you that you have a “dominant yellow face” that was just referring to the color genetics.. dominant pied, yellowface. Not dominant as in personality. Although it seems that might be the case here .
