Spotted
The Medium Ground-Finch is a common and highly variable member of Darwin's Finches, found throughout the Galápagos Islands. It possesses a conical bill of intermediate size, allowing it to exploit a wide range of seeds and insects.
Where to spot
Endemic to the Galápagos Islands, widespread on most of the larger islands, including Santa Cruz, Isabela, Santiago, and San Cristóbal. Found in various habitats from arid lowlands to humid highlands.
How to spot
Look for its medium size and a bill that is intermediate between the Small and Large Ground-Finches. Males are black, females streaky brown. Observe its ground-foraging behavior. Listen for its buzzy, often repeated song, similar to other ground-finches but slightly deeper.
When to spot
Active year-round. Best observed during early mornings or late afternoons when foraging activity is high.

This species is a classic example of natural selection in action; its beak size and shape can rapidly evolve in response to changes in seed availability, demonstrating remarkable adaptability.
