Answer 1

The correct option is A Humming bird

A bind which can fly backwards.

Answer: Humming bird.

The only bird which can fly forward and backward without relying on wind is humming bird.

These birds have an unique wing structure and muscles which give them high level of flight control. They produce $25\%$ of weight support during upstrike and $75\%$ during a down strake with its wings making a figure.

Eight motions.

Humming birds stroke their wings forward and backward, pivoting at one hundred and eight degrees(${108}^o$) about theur shoulders to rotate their wings. They generate lift for both toward and backward stroke, with their wings tracing a horizontal figure. Eight with each beat. A minute turst changes the wing angle and direction of flight.

Figure: Eight motion:

It is a type of motion in which the wings traces the path in the shape of eight. Even our star sun follows figure eight motion.
