So i have a red whiskered bulbul, and it was sick awhile back. Ever since it recovered, i noticed that it experiences something that looks like a seizure to me everyday. This has been ongoing for the past 2-3 weeks, and I'm not sure what it is. It's tail would move up and down violently, wings would flap and its mouth would open and flick its tongue up and down, while seemingly gasping for air or make some sort of squealing sound. It has happened quite often but it doesn't appear to be sick or have any changes to its appetite, so I'm not sure if it's experiencing seizures or if it's supposed to be normal. It's my first bird, and I do not have any experience.. Thank you for your time
