Definition

Noun: 1. A type of stork characterized by a distinctive bill: An openbill is a bird belonging to the stork family (Ciconiidae), genus Anastomus. Its most defining feature is a bill with a noticeable gap or groove between the upper and lower mandibles, which only meet at the base and the tip.

Advanced Notes
