Songbirds are the main group of birds in the order Passeriformes. They are the suborder Passeri, sometimes called 'oscines' (Latin for songbird). They are a genuine clade.
There are about 4000 species of songbird. Their syrinx (vocal organ) is able to produce varied and beautiful singing. They are a very successful group of birds, in fact they are the dominant birds on Earth today.
It seems songbirds evolved 50 million years ago in the part of Gondwana which later became Australia, New Zealand, New Guinea and Antarctica. They then spread around the world.
