T h e woods bordering the eastern sides of the Andes in Peru and Ecuador are the localities inhabited by
this fine species, which differs from all its congeners in the black colouring of its throat and in the
strongly contrasted markings of its bill. It is a rare bird in the collections of Europe ; but fine examples
form part of the Royal Museum at Berlin, and in that of the late Earl of Derby; and were also contained
in the collection of Prince Massena at Paris, now removed to Philadelphia in North America. The specimens
from which my figures were taken were procured by the celebrated traveller Dr. Tschudi during
his researches in Peru.
The figures are of the natural size.
