Amazing as it might sound, ornithologists are still discovering, on average, five or six bird species that are completely new to science each year. What's more, these aren't all just obscure brown birds on tiny islands-- witness the bizarre Bare-faced Bulbul from Laos (2009), spectacular Araripe Manakin from Brazil (1998), or gaudy Bugun Liocichla from north-east India (2006).
