grassquit

plural grassquits

1. Any of several small tropical birds now placed in the tanager family Thraupidae (but previously in Emberizidae), common in the West Indies and in countries of Central and South America around the Caribbean Sea.

   The molecular work also makes a compelling case that Darwin's finches were originally grassquits.

   1988 [1948], David Lack, Notes (for 1988 edition), Darwin's Finches, page xv, Steadman (1982) suggests that Darwin's finches are so closely related to the South American blue-black grassquit (Volatinia jacarina), that all 14 species plus the grassquit should be considered congeners within a new genus, Geospiza.

   The current guess is that it was the wonderfully named dull-coloured grassquit, because this is the bird with the closest genetic code to the Galapagos finches.
