The hamsa (Sanskrit: हंस haṃsa or hansa) is an aquatic migratory bird, referred to in ancient Sanskrit texts which various scholars have interpreted as being based on the goose, the swan, or even the flamingo. Its image is used in Indian and Southeast Asian culture as a spiritual symbol and a decorative element. It is also used in a metaphorical sense with the bird attributed with the mythical ability to extract milk from a mixture of milk and water or good from evil. In Hindu iconography, hamsa is the vahana (or vehicle) of Brahma, Gayatri, Saraswati, and Vishvakarma.
