Polydipsia is an excessively large water intake. Its occurrence in captive birds has been recorded, although it is a relatively rare abnormal behaviour.

Causes

Toxins

Polydipsia can be the result of a bird having ingested a toxin, or overconsumption of natural substances. For example, in pet birds, crackers, snack items, chips, fast foods, and canned vegetables (unrinsed) if eaten in sufficient quantities may cause a mild salt toxicity (5-10 times requirement) and subsequent polydipsia.
