About the Thick-billed Siskin
The thick-billed siskin (Spinus crassirostris) is a species of bird in the family Fringillidae, the finches and euphonias. It is found in Argentina, Bolivia, Chile, and Peru.

The thick-billed siskin has two subspecies, the nominate S. c. crassirostris (Landbeck, 1877) and S. c. amadoni (George, W. G., 1964). Some birds with colors intermediate between those of the two subspecies are postulated to be a third subspecies.
The thick-billed siskin is one of the larger members of genus Spinus and has the eponymous thick bill. It is 12.5 to 14 cm (4.9 to 5.5 in) long and weighs about 19 g (0.67 oz).
