The Red-billed Leiothrix (Bird)

The red-billed leiothrix is a member of the Leiothrichidae family, and it is native to southern China and the Himalayas. It's most distinct features include its bright red bill and the dull yellow 
ring that circles its eyes. The back of the red-billed leiothrix is a dull olive green, and it has a bright yellow-orange throat with a yellow chin. While females are not as vibrant as males, they 
still maintain their dull olive green coloring on their backs. When juveniles first hatch, they have black bills but they eventually turn red once they reach adulthood. In recent years, the red-billed 
leiothrix has been introduced in various parts of the world - most notably in Japan where small populations of them have been living in the wild since the 1980s.

 

The red-billed leiothrix is a common cagebird that goes by various names, such as the Pekin robin, Pekin nightingale, Japanese nightingale, and Japanese (hill) robin. It is not actually native to 
Japan (although it has been introduced and naturalized there), contrary to its last two names.This species was formally described in 1786 by Austrian naturalist Giovanni Antonio Scopoli and placed in the binomial name Sylvia lutea. It is now placed together with the silver-eared mesia in 
the genus Leiothrix that was introduced in 1832 by English naturalist William John Swainson.

 

The scientific name for this plant is a combination of the Ancient Greek words "leios," meaning smooth, and "thrix," meaning hair. The specific epithet, "lutea," is from the Latin word for 
saffron-yellow. Scopoli originally specified the type location as China, but it was later restricted to the mountainous regions of Anhui province.
