Hello, I have a canary that flew in our home 1 year ago. She used to do this from time to time but rarely and it stopped after 2-3 seconds and then all was fine it seemed; She eats normally, drinks normally and she's always on her highest perch (where she always sleeps), she also goes to the bottom from time to time. She is very active and nothing changed in her behaviour besides this: https://streamable.com/nub7dx now she does it constantly and she used to scream from time to time but now all she does is a faint sound as if she lost her voice.
