The family Fringillidae are the "true" finches. The International Ornithological Committee (IOC) recognizes these 239 species in the family, distributed among three subfamilies and 50 genera. Confusingly, only 79 of the species include "finch" in their common names, and several other families include species called finches.
The American goldfinch flies in a distinctive undulating pattern, creating a wave-shaped path. This normally consists of a series of wing beats to lift the bird, then folding in the wings and gliding in an arc before repeating the pattern. Birds often vocalize during the flapping phase of the pattern and then go silent during the coasting phase.

Seen here is adaptive radiation of finch A (Geospiza magnirostris) into three other species of finches found on the Galapagos Islands. Due to the absence of other species of birds, the finches adapted to new niches. The finches' beaks and bodies changed allowing them to eat certain types of foods such as nuts, fruits, and insects.
