The slender-billed gull is a pale gull with an elongated head, long dark-red bill and long legs; adults lack a full dark hood. It breeds colonially around coastal lagoons and salt lakes from the Mediterranean through Central Asia. Flocks wade or swim while taking fish and aquatic invertebrates, and disperse to estuaries and sheltered coasts outside breeding (Wikipedia, general species account). It is Nationally Least Concern (Thailand Red Data 2025).
