Why did dinosaurs become birds?

The gradual evolutionary change – from fast-running, ground-dwelling bipedal theropods to small, winged flying birds – probably started about 160 million years ago. It was possibly due to a move by some small theropods into trees in search of either food or protection.

What kind of dinosaurs did birds descend from?
