The Warbler Finch (Phalaropus tricolor) is one of the famous "Darwin Finches" of the Galapagos Islands of Ecuador. It is the smallest of these finches and has a more slender bill than the others. The first 5 shots on this page are of various individual Warbler Finches on Hood Island in the Galapagos in July, 2007. I have been told that the population of this species on Hood may in fact be declared a new and distinct species at some point in time. These shots were taken with a Canon EOS 1D Mark III and EF 100-400mm F/4.5-5.6 L IS lens.

Darwin's finches (also known as the Galápagos Finches or as Geospizinae) are a group of 15 species of Passerine birds, now placed in the tanager family rather than the true finch family. They were first collected by Charles Darwin on the Galápagos Islands during the second voyage of the Beagle. Thirteen are found on the Galápagos Islands and one on Cocos Island. The birds are all about the same size (10–20 cm). The most important differences between species are in the size and shape of their beaks, and the beaks are highly adapted to different food sources.
