Passeriformes:
A passerine is a bird of the giant order Passeriformes. More than half of all species of bird are passerines. Sometimes known as perching birds or, less accurately, as songbirds, the passerines are one of the most spectacularly successful vertebrate orders: with around 5,400 species, they are roughly twice as diverse as the largest of the mammal orders, the Rodentia. |
