If your cockatiel suddenly starts convulsing, it can be a very alarming experience. Prompt action is crucial. Several factors can cause seizures in cockatiels, and understanding them can help you provide appropriate first aid.
Potential Causes of Seizures in Cockatiels
One of the most common causes of sudden seizures in cockatiels is a deficiency in vitamin B, particularly Vitamin B1. However, heatstroke can also be a contributing factor, especially during hot and humid weather. It's essential to identify the signs of each issue to respond effectively.

Vitamin B Deficiency
A deficiency in Vitamin B1 can lead to a range of symptoms, including loss of appetite, weight loss, weakness in the legs, unsteady gait, decreased activity, reduced vocalization, ruffled feathers, and muscle paralysis. These symptoms can start in the toes and spread upwards to the legs, wings, and neck. In severe cases, a cockatiel might suddenly experience full-body convulsions, often described as "stargazing" with the head tilted upwards and tail sticking up.
First Aid for Vitamin B Deficiency
Immediate supplementation of Vitamin B is essential. For severe cases, intramuscular injections of 10mg of Vitamin B1, administered daily or every other day, might be necessary. For milder cases, adding Vitamin B supplements to their food or water is a good approach. However, ensure that the medicated food or water is not left out for too long as Vitamin B1 can degrade upon exposure.
Heatstroke
Heatstroke is another frequent cause of seizures or convulsions in cockatiels, especially in humid and hot environments. Due to their dense plumage, cockatiels struggle to dissipate heat effectively. Symptoms of heatstroke include panting, rapid breathing, puffed-up feathers, semi-extended wings drooping low, and closed eyes. In severe cases, the bird may lose consciousness and exhibit short, convulsive episodes.
First Aid for Heatstroke
Move the affected cockatiel immediately to a cool, well-ventilated area. Gently mist the bird with cool water every few minutes. If possible, transfer the bird to a room with air conditioning. While the bird may recover quickly from the heatstroke, it might show signs of anorexia, lethargy, and weakness for a few days, making it susceptible to other diseases. Keep a close watch on the bird's behavior. Make sure your bird’s cage is in a cool, well-ventilated area, away from direct sunlight. Always provide ample fresh water, and watch for signs of heat stress during the summer months.
