Geospiza is a genus of bird in the family Thraupidae. All species in the genus are endemic to the Galápagos Islands. Together with related genera, they are collectively known as Darwin's finches. Although in the past, they were classified in the bunting and American sparrow family Emberizidae, more recent studies have shown they belong in the tanager family.
Etymology
The genus name Geospiza derives from the two Ancient Greek words γῆ (gê), meaning "earth", and σπίζα (spíza), a catch-all term for finch-like birds.[1][2]

Hybrids
A purported hybrid species (informally nicknamed "Big Bird") endemic to Daphne Major and formed almost four decades prior by hybridization between a vagrant Geospiza conirostris and a Geospiza fortis was also reported in 2017, though it has yet to be formally described.[4]
