Chapter 4 & 5 Test | Ecology Quiz - Quizizz Crescent Lake is about six miles north of Gig Harbor heading up Crescent Valley Drive to 152nd Street. Darwins finches, named after Charles Darwin, are small land birds, 13 of which are endemic to the Galapagos Islands. With their diversity of bill sizes and shapes, each species has adapted to a specific type of food; the ground-finch (Geospiza) has a thick beak adapted to feeding on a variety of crunchy seeds and arthropods, whereas the warbler finch (Certhidea olivacea) developed a slender, pointy bill to catch tasty insects hiding between the foliage. Ms. McNew and her team captured more than 1,000 individuals of two Darwin's finch species, the medium ground finch, Geospiza fortis, and the small ground finch, G. fuliginosa (Figure 1). These rare finches are only found in a small area on Isabela. There are 11 species pictured in all, each with a slightly different type of environment it occupies.
