Interesting Facts

 The scientific name of the Dusky Thrush commemorates the German naturalist Johann Andreas Naumann.

 It has two distinctive subspecies, T. n. naumanni, and the more northerly breeding T. n. eunomus. These are sometimes given specific status as Naumann's Thrush and Dusky Thrush respectively.

 A group of thrushes are collectively known as a "hermitage" and a "mutation" of thrushes.
