Tail is contracting up and down
(San Mateo, CA)
Hi, we bought 2 budgies back in September. We thought that they were both male, but they really could be boy and girl too, since they seem to snuggle alot.
One of the budgies recently has been acting a bit different with his tail. His (or her) tail seems to be pointed straight down and it seems to contract up and down a bit.
I have made an appointment with an aviary vet, but not for today. I am wondering if this is something that we should be concerned about (and possibly warn our children about gently) or not. What could it be? Is it normal?
