Only hummingbirds and some insects - bumblebees, dragonflies, a couple of others. It's because of the way they move their wings. Most birds gain lift with the downstroke, and minimize the drag created by the upstroke. Hummingbirds actually make an almost figure-eight in the air with their wings, allowing them to get lift (and control direction) on BOTH the upstroke and the downstoke. Because they are always getting lift no matter where they are in the stroke, hummingbirds have complete control of acceleration and momentum in any direction. It also allows bumblebees to grow to ridiculous proportions - they could never fly if they simply used the downstroke as a only power stroke.

No, backward flying in small birds is basic, yet often in basic terms via small birds. The skill mandatory to do it via larger birds makes it greater problematical. The buzzing fowl is often wrongly attributed to be the sole fowl able to flying backwards, yet truly the buzzing fowl is basically the main in demand fowl which hovers and flies backward so elegantly employing its very own skill. See the reference for yet another backward flying fowl.
