Hello, I'm here because my 7yr old cockatiel had similar symptoms and we rushed her to a ER. She was weak, keepjng her beak open, 1 eye open (other partially closed). But still responding to my touch. As soon as the nurses took her in, they called back in 3mins saying she went into cardiac distress. I can't believe she's gone so soon and want to wake up tomorrow with this whole thing a bad dream. I still want to know what happened with her. Any ideas on what could've lead to her collapsing and gone so auddenly? I'm beating myself up as to whether I should've taken her to the ER although I know I couldn't have lived knowing she's suffering. Thanks!
