Among the vegetation behind Gardner Beach on Hood Island (or Española), the finches are especially active. This species is most likely the large cactus finch (Geospiza conirostris). It nests among the pads of giant opuntia cacti and depends on the plant for food (nectar from flowers) as well as food. This species is found only on two other islands.
"A most singular group of finches, related to each other in the structure of their beaks, short tails, form of body and plumage." Charles Darwin Voyage of the Beagle 1845
