What can cause seizures in birds?

Seizures in birds can be caused by a variety of factors, with low blood sugar (hypoglycemia) and high stress being among the most significant. Birds have a high metabolic rate, and their energy levels are closely tied to their blood sugar. When a bird experiences low blood sugar, it can lead to neurological symptoms, including seizures. High stress can exacerbate existing health issues or contribute to unstable metabolic conditions, leading to similar outcomes.

Factors such as excessive exercise, overfeeding, and feather loss may impact a bird's overall health and well-being but are less directly linked to the acute neurologic events like seizures. For example, while excessive exercise can lead to fatigue and possibly other health issues, it is not a primary cause of seizures in birds. Overfeeding may lead to obesity and related health complications, yet it does not typically influence seizure activity directly. Feather loss might indicate stress or health issues, but it does not independently cause seizures either. Therefore, the combination of low blood sugar and high stress stands out as the primary cause of seizures in birds, making it the correct answer in this context.
