He’s mad at him

Hi, we’ve had Mr. Gray since Dec. 2023. He’s our daughter bird. He used to go to my husband and land on his head and my husband would have him step up on his finger. And they would talk and play for awhile. Then my husband got sick congestive heart failure; now Mr. Gray will land on his head and go into attack mode. Sometimes he’ll step up onto his finger seem normal then attack mode. Also sometimes when he flies to my husband head he has claws out beak open like fighting mode. Why now is he doing this?

Thank you for reaching out to Ask Lafeber. It’s very common for a cockatiel’s behavior to change when a major change happens in the household, especially when a person they are bonded to becomes ill or their routine shifts. Mr. Gray likely associated your husband with positive, predictable interactions before his health issues, and now he may be reacting to changes in your husband’s scent, posture, energy level, or movements, which can confuse or unsettle a sensitive bird. Cockatiels often show this confusion as defensive behavior—flying in with claws out, beak open, or switching suddenly from stepping up to “attack mode.” This doesn’t mean he dislikes your husband; it usually means he’s unsure and overstimulated. The best approach is to rebuild trust slowly with calm, predictable interactions: have your husband speak softly to him, offer treats from a distance, and avoid letting him land on his head until he is reliably calm again. Short, positive sessions can help Mr. Gray relearn that your husband is safe and familiar.
