If the air sac mites wasn't enough,i have now found out that what I thought was my Goulding finch male dancing is infact stargazing! he dosnt do it all the time but for a while every day he twirls his head around and upside down

Is this true? and has anyone else experienced this? my mate is very kind and has said he will sort me out another pair of birds at some point, hes also very confused as hes never had these problems before with his finches, I'm not having the best of luck with my return to finches.
On the plus side though my society finches are doing very well and seem happy as lary
