Seizures in Macaws: Causes, Emergency Care, and When to Call a Vet
- See your vet immediately if your macaw has a seizure, even if it stops quickly.
- Move your macaw to a quiet, dim, padded space and remove perches, toys, food, and water until balance returns.
- Common causes include lead or zinc toxicity, head trauma, low calcium or low blood sugar, liver or kidney disease, infection, heat stress, and less commonly a brain disorder.
- A seizure lasting more than 5 minutes, repeated seizures in 24 hours, collapse, trouble breathing, or known toxin exposure is an emergency.
- Bring a video of the episode, a list of recent foods and household exposures, and any chewed metal items or toys to your appointment.
What Is Seizures in Macaws?
See your vet immediately. A seizure is a sudden burst of abnormal electrical activity in the brain. In macaws, it may look like falling from the perch, stiffening, paddling or jerking of the wings and legs, loss of balance, vocalizing, defecating during the episode, or a period of confusion and exhaustion afterward.
Seizures are not a disease by themselves. They are a sign that something is wrong, and in birds that "something" can range from toxin exposure to metabolic disease to trauma or infection. VCA notes that birds often go through an aura phase, an active seizure phase, and then a post-ictal recovery period that can last minutes to hours.
Because macaws are curious chewers, heavy metal exposure is a major concern. Lead and zinc from cage hardware, toy parts, clips, chains, paint, or household items are well-known causes of neurologic signs in pet birds. Even one seizure deserves prompt evaluation, because birds can hide illness until they are very sick.
Symptoms of Seizures in Macaws
- Sudden loss of balance or falling from a perch
- Body stiffening followed by wing or leg jerking
- Paddling movements or uncontrolled flapping
- Temporary unresponsiveness or staring
- Vocalizing during the episode
- Defecation during or right after the event
- Post-episode weakness, exhaustion, or confusion
- Restlessness, agitation, or poor coordination after the seizure
- Head tilt, tremors, or repeated brief twitching between episodes
- Collapse, trouble breathing, or repeated seizures, which are severe emergency signs
Not every collapse is a seizure, but any sudden neurologic episode in a macaw is urgent. Worry more if the event lasts longer than a few minutes, happens more than once, follows chewing metal or paint, or is paired with weakness, green droppings, vomiting, trauma, or breathing changes. A video can help your vet tell the difference between a seizure, fainting episode, toxin exposure, or another neurologic problem.
What Causes Seizures in Macaws?
Macaws can seize for many reasons, and several are treatable if found early. One of the most important causes in pet birds is heavy metal toxicity, especially lead or zinc. VCA lists lead and zinc ingestion among the more common causes of seizures in pet birds. Sources can include galvanized wire, cage clips, chains, bells, costume jewelry, curtain weights, paint chips, pennies minted after 1982, and some imported toy parts.
Other possible causes include head trauma, overheating, low blood calcium, low blood sugar, severe liver or kidney disease, atherosclerosis related to poor diet, and infections that affect the brain or nervous system. Birds on unbalanced seed-heavy diets may be at higher risk for nutritional problems, while birds with access to unsafe household items may be at higher risk for toxicosis.
In some cases, your vet may not find a single clear cause right away. That does not mean the episode was harmless. It means your macaw may need stepwise testing, close monitoring, and sometimes treatment aimed at both seizure control and the underlying problem.
How Is Seizures in Macaws Diagnosed?
Your vet will start with a careful history and physical exam. Expect questions about the exact timing of the episode, diet, supplements, recent falls, new toys or cage parts, access to paint or metal, and any changes in droppings, appetite, or behavior. If you have a video, bring it. That can be one of the most useful tools in the room.
Initial testing often includes bloodwork to check glucose, calcium, electrolytes, and liver and kidney values. VCA also notes that blood chemistry testing helps assess metabolic causes, while imaging may be used to look for metal particles or other internal problems. Whole blood lead or serum zinc testing may be recommended if exposure is possible.
Radiographs can help your vet look for swallowed metal, enlarged organs, egg-related issues in females, or signs of trauma. Depending on what your macaw is showing, your vet may also discuss infectious disease testing, fecal testing, or referral to an avian specialist for advanced imaging and hospitalization. Diagnosis is often a process of ruling out the most dangerous and most treatable causes first.
Treatment Options for Seizures in Macaws
Spectrum of Care means you have options. Here are treatment tiers at different price points.
Budget-Conscious Care
- Urgent exam with your vet or emergency triage
- Safe stabilization advice for transport
- Basic physical exam and weight check
- Targeted history review for toxin, trauma, and diet risks
- Limited diagnostics such as focused blood glucose/calcium check or a single-view radiograph when available
- Outpatient supportive care if the seizure was brief and your macaw is stable
Recommended Standard Treatment
- Urgent avian exam and neurologic assessment
- CBC and chemistry panel with calcium, glucose, and organ values
- Radiographs to look for metal, trauma, or internal disease
- Whole blood lead and/or serum zinc testing when indicated
- Injectable or oral medications to control active seizures if needed
- Fluids, heat support, nutritional support, and short hospitalization or observation
Advanced / Critical Care
- Emergency hospitalization with continuous monitoring
- Repeated anticonvulsant treatment for cluster seizures or prolonged seizures
- Oxygen, IV or intraosseous fluids, assisted feeding, and padded cage care
- Chelation therapy and serial metal testing if lead or zinc toxicity is confirmed or strongly suspected
- Advanced infectious disease workup and specialist consultation
- Referral imaging or other advanced diagnostics for complex neurologic cases

Questions to Ask Your Vet About Seizures in Macaws
Bring these questions to your vet appointment to get the most out of your visit.
- Based on my macaw's history, what causes are most likely right now?
- Do you suspect lead or zinc exposure, and should we do radiographs or metal testing today?
- Which blood tests are most important first if we need to prioritize the cost range?
- Does my macaw need hospitalization, or is home monitoring reasonable after this episode?
- What emergency signs mean I should come back immediately tonight?
- If seizures happen again, what should I do during transport and what should I avoid?
- Are there diet or supplement changes that may help if calcium, glucose, or organ disease is involved?
- When should we recheck bloodwork, radiographs, or metal levels?
How to Prevent Seizures in Macaws
Not every seizure can be prevented, but many risk factors can be reduced at home. Start with the environment. Check cages, play gyms, chains, clips, bells, hardware, and household items for lead or zinc. Avoid access to paint chips, stained glass supplies, fishing weights, pennies, batteries, costume jewelry, and unknown metal parts. If your macaw is a strong chewer, routine safety checks matter.
Diet also plays a role. Feed a balanced, species-appropriate diet rather than relying on seeds or high-carbohydrate human foods. VCA notes that nutritional imbalance and atherosclerosis can contribute to seizure risk in birds. Ask your vet whether your macaw's current diet supports healthy calcium balance, liver health, and body condition.
Prevent trauma and overheating whenever possible. Supervise out-of-cage time, reduce crash risks around windows and mirrors, and avoid heat stress during travel or warm weather. Regular wellness visits with your vet can help catch subtle weight loss, organ disease, or toxin exposure before a crisis happens. If your macaw ever has another episode, keep a seizure log with date, time, duration, video, and possible triggers.
