My cockatiel's wing is bleeding. Is it serious? Should I separate?

Thanks for reaching out about Buddy and including photos. This is evident of trauma, could this bird be getting scared in the cage and flying/hitting the cage bars? Decreasing stress will hopefully allow to calm down. If suspect injury or appears painful, a veterinary visit is recommended. Good luck.

If there is no visible injury but Kody still seems agitated, giving him a chance to rest and relax by keeping his cage quiet and dark may help him to settle back in. I would keep an eye on him, and if he stays agitated or doesn't return to normal after 24 hours, have a vet take a look to make sure there isn't an injury or issue causing his distress.

Thanks for reaching out about Oscar and including photos. Did you have wings trimmed recently? This appears to be a contusion on the tissue close to the vent (but not) that happens when cockatiels jump/fall, wings are over trimmed and they hit the ground hard. The tail becomes hyper-extended dorsally, ripping the skin. The wound needs to be cleaned, and systemic antibiotics can assist with infection prevention. A veterinary visit is recommended. Lower perches to 3-6 inches above the bottom of the cage, place a soft towel to lighten falling. Good luck.

Thanks for reaching out about Ozzie and including photos. Those primary feathers appear to have been trimmed, with the possible cutting of a blood feather. If not actively bleeding, a veterinary visit is not needed. Good luck.

I'm sorry to hear Baby got so startled! I would examine the wing he is chewing on/having trouble with to check for any injuries or wounds that may be obvious, and also limit his activity for a day to see if it helps with any minor injuries. If you suspect the wing is broken or there is a broken or torn blood feather, seeking veterinary care right away is best for treatment.

Trying to alleviate the cause of Daisy's stress may help. If she's in an area with a lot of noise or foot traffic, moving her to a calm, quiet room may help. Making sure she isn't being harassed by other people or pets, and that she has access to food, water, and perch space if she's housed with other birds can help. Toys that encourage chewing, preening or activity can also help alleviate boredom and redirect the chewing behavior to those instead of herself.

Poor Grey! If the bleeding has stopped, I would keep an eye on him and If he has any trouble breathing, there is a large visible wound or crack on the beak, or he isn't eating or drinking, then I would seek veterinary care ASAP as these are all signs that the issue is more serious and requires treatment by a veterinarian.
