The term 'Brown Songbird' encompasses three species of birds: the LARK, WREN, and THRUSH. The LARK is a small, brown bird with a melodious song, found in open country across much of the Old World. The WREN is a small, brown bird with a loud, complex song, found in Europe, Asia, and North America. The THRUSH is a medium-sized, brown bird with a beautiful song, found in woodlands and gardens across much of the Northern Hemisphere. All three species are known for their beautiful songs and are a delight to hear in the wild.
