The correct spelling of the word "moorbird" is actually "moorhen" with the phonetic transcription /mʊə(r) hɛn/. The "r" in parentheses indicates that the "r" sound is optional in some dialects. Moorhens are waterbirds that are commonly found in wetlands and are known for their red bills and yellow legs. They are also referred to as marsh hens or swamp chickens. Despite their name, moorhens are not related to chickens but are actually part of the rail family.
