Hello I have two cockatiels and in the last two months or so she has been doing this thing that looks like a yawn but she does it repeatedly and she does not do this everyday but like one a week or so when I put the water in front of her she sometime drinks a sip and sometimes she doesn't I have seen videos of other birds doing almost the exact same thing but I don't know if this is okay I any knows what it could be let me know I know their is a possibility that it could be that she is pushing food down and she also does this at around this time ( the late afternoon )
Any help is highly appreciated
