SOME OF DARWIN’S FINCH’S ORIGIN OF NAME BY DISTINCTIVE TRAITS ESL: TEACH THE TEACHER Geospiza conirostris GEO = Earth Spiza= Española Con = With Rostris (Rostra) = Face Geospiza fortis Geo = Earth Spiza = Española Fortis (Fortisimo) Geospiza magnirostris Geo = Earth Spizo = Española Magna = Large Rostris (Rostra) = Face Geospiza diﬃcilis Geospizo = Española Diﬃcil = Diﬃcult Darwin classified this finch based on the bird’s origins from the Galapagos Islands, located oﬀ the West Coast of Ecuador. It is unknown why he used the word rostra meaning face. Possibly because he used this bird as the original, for all others to be compared to. Darwin classified this finch based on origin and for the birds very strong (fortisimo) beak and vocal range. Darwin and Gould classified this finch based on the same geography as the others but noted that this finch had the largest face of the 15 finches of the islands. Can you guess why Darwin with the help from his Orinthologist friend, John Gould, named this bird? It is unknown. However, ornithologists have described this bird as “aggressive with a painful beak” (Audubon Society 2002).
