Fam. I. TURDIDÆ, or THRUSHES.
Eight species of the almost cosmopolitan Thrush-family are known to
occur in the Argentine Republic. Of these, five belong to the
widely-spread genus _Turdus_, and are closely similar in structure to
our European Thrushes. The remaining three are Mock-birds (_Miminæ_)--a
group restricted to the New World, and sometimes considered more nearly
allied to the Wrens. They are remarkable as splendid songsters.
Burmeister includes in his list a fourth species of _Mimus_ (_M.
thenca_), as found in the Mendoza district; but there may be some
error in this, as _M. thenca_ is only known to us from Chili west
of the Andes.
