Whitethroat is an old-world migratory bird that is divided into two broad classifications, the lesser whitethroat, and a more commonly visible species known as greater whitethroats. The greater whitethroat is popularly referred to with the name common whitethroat. It is a medium-sized warbler with a long tail and is distinguished from the lesser whitethroat species by some typical physical differences. As they are spread over a large territory, whitethroats are also known by some other common local names like hay jack, beardie, and nettle creeper.
