Finches are small birds, and are active and fun to watch, and quiet when it comes to vocalization (chirps and peeps that most people find easy to tolerate).

Although small, they need a fairly large cage in order to have flight room (the length of the cage is more important than the height). All finches are social and should be kept in pairs - and a male and female pair will usually breed quite readily so you may want to consider keeping only females. They are good for watching but not for handling.
