The pied avocet is a relatively large wader about 40cm long with a wingspan of about 70cm. It feeds on various invertebrates in water and on mudflats, caught with its distinctive upturned bill (Wikipedia, general species account).
It typically nests in colonies of 10 to 70 pairs on islets or dikes near water, laying usually four eggs in a simple, shallow scrape in the sand. The sources read give no plumage or range detail, and do not name Bhutan, so its occurrence there is flagged for checking.
